Adolf-Kolber-Strasse, Köln , 2023

The composition of three basic types, the “Laubenhaus” (arcade house), “Zeilenhaus” (row house) and “Punkthaus” (point house; multi-storey building with a central circulation core), allows for the response to various requirements in terms of urban space and the adjustment of the housing mix according to demand. The slightly increasing building height allows both the required room schedule to be realised with a minimal footprint and the preservation of the impressive tree population. An opening between the buildings promotes air circulation between the park and the street. A tall buildings adds accents, the balconies are turned outward, dividing the urban space, and the slightly set-back “Laubenhaus” creates a forecourt for the day-care centre.

A coordinated colour scheme for the façades, as well as a modular grid with various infill options, window heights and balustrades, gives the buildings their own character and recognisability despite high seriality. The proposed building volumes are modular and planned as timber hybrid constructions. The structural system consists of precast concrete floor slab elements with solid wood columns. To ensure recyclability, adhesive connections are avoided. The façade is conceived as a timber frame construction with infills of mineral wool insulation and planking on both sides.

The redesigned open space serves as one of the most important public areas in the neighbourhood. It connects the green spaces of all construction phases. The publicly accessible, connecting green corridor provides high-quality recreational areas for all residents, including various play areas, a community meeting point and areas for urban gardening.

KAEPSELE, Leinfelden-Echterdingen , 2022, 1st Prize

As part of the IBA’27 Stuttgart Metropolitan Region, a quarter with the highest ecological and social standards is to be created on the Goldäcker area on the outskirts of Leinfelden-Echterdingen. The new neighbourhood is conceived as a showcase project for a sustainable society. This uniqueness should also be perceptible in the architectural expression. Sustainability should not appear as an applied feature but rather be understood as an inherent component of the architecture. The houses are like small power plants, drawing their energy from the sun and the ground, and reusing materials from previous construction projects. The goal is to develop a resilient quarter that can be flexibly used by future generations according to their needs and over an extended period.

The fundamental concepts of the existing master plan are embraced: the integration between the city and the landscape, the central core, and the intermediary building heights towards the existing structures. By slightly turning the repeating buildings, intriguing urban spaces intertwined with the landscape are created, guiding visitors into the quarter. The layout of pathways constantly generates new visual connections. The buildings are consolidated with a minimal footprint, allowing for adequate greenery and ventilation despite a dense room programme. The staggered arrangement of the buildings with corner apartments provides views into the distance.

Campus Golzheim, Düsseldorf , 2023

The Golzheim Campus transforms existing and new buildings into a forward-thinking quarter with a central green space. The existing structures are continued and complemented.

The buildings of the music college and the district government office jointly present a new face for the area facing Kennedydamm. The ensemble of buildings naturally integrates into the surroundings and establishes a direct dialogue between the two new uses. The central campus square extends between the two new buildings. This large, central and high-quality outdoor area serves as both a place to linger and a communication area. By referencing the prevailing façade lengths, the new buildings blend into the evolved cityscape. The perception of the structures is pleasant, and the human scale is preserved. The staggered heights of the buildings continue and complement the character of the dense and diverse environment.

The decision is consciously made to forego additional state-related uses in order to take advantage of the opportunity to de-seal the area and create a spacious, continuous outdoor space. The green corridors also represent an added climatic value for the neighbouring areas by creating cooling fresh air currents. The compact positioning of the new buildings along existing green structures allows many trees to be preserved. The second blue-green ring is extended by connecting it to the overarching cycling and pedestrian network. The further urban development involving the construction of the district government office will incorporate the existing structures.

Due to the planned relocation of Beiersdorf AG’s corporate headquarters, a new residential quarter is to be developed on the company’s site, which is situated in the middle of the lively Eimsbüttel district, between Unnastrasse and Quickbornstrasse, and currently not accessible to the public. One focus is on the design of the streets, alleyways and squares of the new quarter, which will blend in perfectly with the neighbourhood. An individual design canon, applicable to all the individual building sites, strengthens the specific characteristics of the quarter and thus creates identity and recognition value. It includes differentiated specifications for building volumes and façade design along Quickbornstrasse and Unnastrasse, for alleys in the quarter and for the Y-shaped residential alley. The new buildings along Quickbornstrasse and Unnastrasse feature typical elements such as the three-part division into plinth, middle section and attic zone and the vertical rhythms of the façades achieved by means of projecting bays and balconies. Red brick typical of Hamburg is used in a variety of colours as an expression of high-quality living. Diverse, variable and contemporary residential typologies are designed to enable living in every phase of life in the new Beiersdorf quarter and to guarantee diversity. Large family flats, dwellings for singles, cluster flats, assisted living, studios for students, subsidised housing and special soundproofing typologies ensure a good mix of uses. A balanced ratio of extensive greening, green areas and roof terraces makes it possible for residents to use the rooftops and promotes biodiversity in the urban space.

The direct juxtaposition of living and working is both space-efficient and creates a feeling of generosity: rooms used for working can serve as an extension of the living space during leisure time (and vice versa). A total of 8 serially connected sections provide 15 residential units, with each section comprising two stacked 3.5-room studio flats with a connectable workshop/study.

Meltingport Hafencity, Hamburg , 2022, 2nd prize

In the HafenCity, currently the largest inner-city development project in Europe, a new meeting place for work, living and accommodation is being created on the construction sites 103/104: the “Meltingport” at Baakenhafen. The focus is on networking the various uses and their players. Inspired by the architecture of Hamburg’s Kontorhäuser – historical office buildings – and the Speicherstadt (the listed warehouse district), the new buildings integrate into the urban environment. The red brick façade is characterised by a functional expression of the different uses combined with playful design elements: horizontal and vertical bands, coloured highlights using green glazed bricks, different window sizes and “accessories” such as coloured shutters. On the ground floor, the otherwise very clear separation of uses becomes blurred. Thus, the courtyard is the epitome of the “Meltingport” and provides an interactive connection point where different people come together. With a restaurant, rooftop bar, fitness and wellness area, and a small stage in the lobby, the hotel has many opportunities for networking among visitors. Innovative research and work concepts – such as the Data Café, a Startup Hub and co-working – are accommodated in the office building. By providing common rooms and small stores, student housing in the south part of the complex offers a good mix of private and public meeting places for the approximately 200 residents.


The exhibition pavilion on the redeveloped Hopfenmarkt is an analogy to a roofed excavation site. It spans the “incision” into the underworld, where the foundation walls of Hamburg’s first settlement are being uncovered and will be open to visitors in the future. Its orientation follows the underground rampart, thus evading the “above-ground” directions of the Hopfenmarkt and the church ruins with a slight twist. At the same time, the pavilion represents a reminiscence of the market halls, which existed here for a long time. The minimalist spatial schedule consisting of an entrance area with a cash desk and a small café/bar, as well as the associated ancillary uses, is housed in a hall of light that illuminates this special place like a lantern in the evening hours. Two mirror-symmetrically arranged staircases take visitors down to the exhibition area and, at the end of the tour, lead them back up into the foyer and to the newly designed park. A pavilion architecture in timber construction: a typical construction method for temporary buildings, wood as a traditional and archaic building material. The new building plays with the factor of time, wants to refer to the fleetingness of history, to the overlapping of different historical layers at this place and thereby acquires its very own identity as a counterpart to the stone ruin of the Church of St. Nicholas.

Directly on the banks of the Aare, between Erlinsbacherstrasse and the Kraftwerkskanal, a mixed-use and sustainable development with 60 to 70 rental flats will be built from 2024 onwards. The twin houses of the new chain of buildings are positioned in such a way that heterogeneous spaces are created in between, ensuring permeability and open spaces. The ground floors accommodate community rooms, a day-care centre, and commercial units. A bistro is also planned to provide a meeting place for the new residents and enrich the neighbourhood. All the buildings have been moved away from the noise-critical area facing the Aare, meaning that costly noise-reduction measures are no longer necessary. The three- to four-storey houses are designed as timber frame constructions with staircases made of prefabricated clay cast elements. The use of concrete as a building material is to be avoided to the greatest possible extent. A ground-source heat pump in each building and photovoltaic systems integrated into the roofs and façades supply the residential ensemble with energy. All flats boast views to two or even three sides and thus benefit equally from the attractive riverside location. The living concept is based on a simple system of use-neutral rooms around a central living space. This makes the same type of flat work for a family with many children, for a couple working from home or even for people sharing a flat.

Integration into the cityscape, added value for the community, green working environment, resource-saving construction.

For an office building on Invalidenstrasse, Berlin, we are planning two efficiently shaped buildings using as few materials as possible, resulting in an ensemble of diverse townhouses. It is accessed via a shared central entrance adjacent to the green courtyard. The sculptural terracing of the office buildings creates a lot of space for greening the inner courtyard and merges the new project into the existing ensemble. The multifunctionally usable floor plan typology, in the style of 1920s factory buildings with bundled installations and pure usable space, allows for long-term user flexibility.

This project is based on the underlying question of what is the difference between village and city. Two houses that resemble each other but are different in size are joined together to form a single unit. They are vaguely reminiscent of a farm: a residential building with a farm building next to it. The roofs leaning towards each other create a pseudo-symmetry and ambivalence in their legibility. Something new is created here in the familiar, and the individual merges with the big picture. The outdoor spaces are differentiated into different levels of openness to the public and focus on the central village square. The housing mix is characterised by diversity and ranges from studio apartments to a three-storey cluster flat. The entrance halls with adjoining laundry rooms serve as meeting places, and overarching uses such as a multi-purpose hall, a day-care centre or the small sacred room create a well-dosed public realm oriented towards the village square. Voids, maisonette typologies with galleries and recessed patios form exciting spatial sequences and attic flats with very individual characters.

Gröninger Hof, Hamburg , 2021, 1st Prize

Where cars used to be parked, vibrant living, working and a diverse togetherness will soon be possible. A stacked urban landscape surrounded by plenty of greenery – all under one roof in the centre of Hamburg’s inner city – is an enormous opportunity with exemplary character! Thus, the repurposing of the multi-storey car park is much more than just the conversion of an existing building, but above all a contemporary expression of social and ecological change. The typology of the traditional Hamburg Kontorhaus with a narrow inner courtyard is taken up and combined with the idea of a vibrant green space that emerges from the building’s interior as a meticulously designed roof and terrace landscape.

The hybrid uses are enveloped by well-proportioned façades, urban and prestigious towards Neue Gröningerstrasse, quoting familiar elements from the existing building and the immediate surroundings, while a completely independent world opens up in the inner courtyard. The open ground floor integrates the public streetscape, welcoming visitors and residents alike. The large, roofed entrance area creates added value for the entire neighbourhood through the variety of possible uses. Access to the apartments is provided via two lateral entrances and the central inner courtyard, where one moves in a circular pattern along spacious arcades, each of which is connected on the narrow sides by lifts and open staircases. The “high point” of Gröninger Hof is the generous roofscape with further communal uses such as a laundry room, sauna and fitness room, and a rooftop garden with a play area and flowerbeds.

Kaarst is diverse and entertaining, full of flair and familiar atmosphere. We focus on four core ideas to promote these valuable characteristics: four characterful themed squares, curated diversity of uses for the commercial areas, clear address generation, promotion of pedestrian traffic, cycling and public transport. In terms of urban planning, the new building masses fit naturally into the evolved cityscape, creating spatial edges and the density necessary for a city centre. Four squares emerge. The buildings naturally redirect the flows of movement along the green axis. The squares are distinguished by their individual characters; they are deliberately assigned specific uses in order to strengthen them. In the future, pedestrian and cycle traffic in particular will be promoted. The number of above-ground parking spaces will be reduced, whereas the existing underground car park at the roundabout will be extended along Maubisstrasse to accommodate a significantly larger number of cars. The underground car parks underneath the new buildings together with the Mobility Hub and the promotion of public transport will also help to ensure that sufficient parking spaces are available for visitors. The market square literally rolls out a carpet for urban life. The ornamental paving of the square naturally connects its northern and southern parts. A variety of uses are conceivable on the open square. The music pavilion is a stage for small music events at weekends, which create an atmospheric attraction for Kaarst’s town centre.

In HafenCity, the City of Hamburg has the unique opportunity to realise urban living on the waterfront in the former port with direct access to the city centre. Baufeld 98 is in an attractive location at Baakenhafen and Baakenpark. Between Baakenallee and Peterskai, a ‘string of pearls’ of meandering solitaires will be implemented, creating small forecourts along the street and more private spaces towards the water. The result is a ‘breathing’ development that is formed by the public space between the buildings and thrives on the visual references to the harbour basin. As part of this meandering structure, we are developing a building cubature for Baufeld 98, which will feature an expressive silhouette towards the water. A greenhouse on the rooftop is a transparent green crown that forms the building’s identity-generating signet. The façade facing Baakenallee, on the other hand, has a classical urban appearance with a harmonious symmetrical rhythm comprising bay windows and balconies.

The former site of Heidelberger Druckmaschinen and the municipal utilities is located on an enclosed area between the roads Alte Eppelheimer Strasse and Kurfürsten-Anlage, in the middle of the lively Bergheim district. Its seclusion, which does not allow any public passages, shields a “terra incognita” from the outside and divides the quarter at this point. Our design reverses the current situation of the enclosed area: pathways and visual axes open up the new residential quarter, interlocking it with the adjacent urban fabric in a north-south direction towards the river Neckar. In an east-west direction, the specially created “alley” acts as the backbone of the new car-free quarter and connects the station forecourt with the new local square in front of the public utilities. The chimney, now used as a lookout tower, will become the new “landmark” for a place of change. The new identity will be symbolised by the redesigned boulevard, which begins with the solitary building of the Print Media Academy on the station forecourt and ends in the new centre – the local square. Its design is based on generous European promenades with old trees – on the one hand a circulation axis, on the other a lively place to spend time in the middle of the city. An attractive area for both pedestrians and cyclists is created. Small shops and cafés flank the promenade and generate a lively atmosphere.

Like many other villages, Kaltbrunn is characterised by a heterogeneous, disparate settlement pattern and the linear expansion of the village centre along two development axes. We believe that the linear placement of the buildings and the proposed courtyard typology offer an opportunity to develop the village centre inwardly and, at the same time, to preserve the linear structure of the ribbon-built village. We regard the much-criticised heterogeneity of settlement structures in agglomeration communities as a potential. Our aim is not to create harmony and uniformity with a large-scale building, but to transform the unmediated small-scale juxtaposition of three different building types into a high-contrast coexistence. The surrounding street spaces, with which the new building blocks enter into an individual dialogue, determine the morphology. In contrast to this, the semi-public centre forms a public courtyard that, with the floating roof of the community hall, can become a pulsating heart of the housing development. Individually tailored, innovative and needs-oriented forms of housing allow for a variety and mix of uses. This ensures a socially and economically stable and lively estate in the long term. Extra rooms for rent, music, laundry and common rooms are available, which, in addition to the circulation zones such as arcades and exterior staircases, provide spaces for encounters. A crèche, a café and a youth room expand the amenities on the estate level.

We propose a tower without a plinth, so that as much space as possible can be freed up for public space in the densely built-up area. The tower is staggered upwards in four segments. The lowest edge makes important horizontal references to the neighbouring development. The inner logic of the high-rise building is based on the idea of a vertical neighbourhood. For this purpose, three storeys each are merged via a central, open centre. This piazza is the arrival point, distribution space and gateway to the apartments. A total of 10 neighbourhoods with about 22 residential units each are created. Resident profiles with similar needs are grouped together. The variety of apartment typologies is only made possible by the innovative structural concept and the consistent separation of primary and secondary structures. Two tubes inserted into each other are designed as load-bearing elements. The “tube-in-tube principle” of the famous steel frame constructions from 1950s Chicago is thus translated into a future-oriented construction made of the renewable raw material wood. Bracing is provided by the two interconnected tubes.

Kiosk for the new Enge harbour promenade, Zurich , 2021

  • Architecture: Duplex Architects, Landscape architecture: Vogt Landschaftsarchitekten AG, visualizations: Vivivd Vision

The kiosk does not want to be more than it is. It is not a sculpture or an object seeking attention but carefully placed functional architecture. A place where you can get something to eat, with two integrated toilet units. It doesn’t pretend to be either big or small, it simply stands there. The kiosk has a lengthwise orientation, like the promenade itself, and seeks the proximity of the large pagoda trees that fill one end of the harbour promenade. The sloping “nose” stretches out towards the open space, a canopy offers shelter. On the other side, one is welcomed by a bench. There is no back, the small building is accessible from all sides. Facing the lake, generous glass display cases offer enough space to present small delicacies. The lift-up windows can be opened individually so that – depending on the season – one, two or even three people can work side by side. In the cold season, only the two front windows are open so that the interior does not cool down too much. When there is a big rush, the length helps to ensure a speedy process. The roof construction offers space for a robust wooden roller shutter, which provides a secure barrier at night and in winter months. In the evening, the kiosk can be closed in a few easy steps. The roof is detached from the building structure and mounted on the wooden substructure. The glass strip makes the kiosk appear light and permeable from both sides. Thanks to the parallel flanks, the building blends in well with the building lines without completely subordinating itself to the flow of movement. After all, this kiosk on the new harbour promenade is allowed to have a little edge to it.

Bell Areal, Kriens , 2020

  • © architecture: Duplex architects; visualisation: ​indievisual AG

Like many other Swiss agglomerations with an industrial character, Kriens is distinguished by a heterogeneous, disparate settlement pattern and the linear spread of the town centre along a development axis. We see the opening up and urban development of the Bell grounds as an opportunity for developing the depth of the town centre and, at the same time, maintaining the linear order of the former ribbon village. In our view, the much-criticised heterogeneity of settlement structures in agglomeration communities is a potential. We are not aiming to create harmony and uniformity, but to transform the direct juxtaposition of different settlement types into a high-contrast coexistence. The surrounding streetscapes determine the morphology, and each of the new building blocks enters into an individual dialogue with them. The new centre with park and halls is interwoven in terms of urban space and function with differently designed stepping stones to the area. As plaza-like access points, they offer public services tailored to the context and therefore also mediate functionally between the two worlds.
The partial conversion of the Bell factory is intended to express both the diversity required for the development of the Kriens town centre and the identity of Kriens’ industrial history.

Gebuur, Antwerp , 2020

  • © Architectur: Duplex architects and BRUT; visualizations: Asymetrie

“Gebuur” or in English “neighbourhood” develops urban living for families: here you will find everything a family is looking for, from space to flexibility, within the social fabric of the city and a green environment. In other words, “Gebuur” is a generous response to the needs of families in the city. The flexibility of the building and the variety of functions in the common areas offer more than a traditional single-family house – whether in the city or elsewhere. “Gebuur” focuses on special spaces that complement one’s own home: the “Werft” (the common hall), the “Lochting” (the roof garden) and various “Veurdielen” (communal spaces). These areas are shared either with one’s family, one’s immediate neighbours or with all the residents of the building block. Thanks to an intelligent stacking of single-family houses, each flat in the “Gebuur” has its unmistakable presence, with an emphasis on identity and appropriation. The transition between public space, collective supply and private flat ensures a feeling of coming home. Each flat has a high-quality private outdoor space in the form of loggias, terraces, French balconies or gardens. The gardens located internally combine to form the courtyard, a collective green space, its scale matching that of the building block. Like classic front gardens, they are the green décor that all residents can enjoy together. At the same time, it also provides a unique view of the Cadix neighbourhood. The courtyard is a safe play area for children and an informal meeting place for residents, similar to that found in residential areas outside the city.

Despite the given depth of the site, we are proposing a self-contained, point-like building—a solitaire of five stacked cubes tapering upwards and prominent in every direction. The ground plan with the shape of a free quadrangle is derived from the immediate urban context of street, building alignments and visual axes. The differentiated heights are in dialogue with the different building heights of the heterogeneous surrounding developments. This building is intended to counteract the mono-functional concept of high-rise buildings by creating a new vertical urban quarter featuring a broad mix of uses. Each of the five cubes houses its own programme, allowing the functional diversity of the building to be experienced in its design. Besides being quiet places for residents to spend time, the spacious terraces and roof gardens serve as communal gardening and cultivation areas in a dense urban context. A balanced ratio of extensively and intensively planted roof gardens enables the integration of various aspects of the local climate and the promotion of biodiversity in the urban space.

Im Gut, ZÜRICH , 2020

  • Architecture: Duplex Architects, visualizations: Paulina Bonowicz

Both building sites have at least one façade that is exposed to noise. While on site A the south façade cannot comply with the limit values at night, the north and east façades on site D are affected by street noise. The floor plans therefore differ according to the situation. On the northern building site, the interplay of the floor plan arrangement and the volumetric design of the buildings results in an exciting typology for housing with noise exposure: a generous sequence of rooms consisting of living, dining and cooking areas extends between the street and the garden, allowing ventilation of all rooms via the quiet façade. Large balconies extend the living space into the garden. The volumetric measures, such as bay windows and loggias, on the southern building site achieve an effective noise protection effect. The open room sequences always link two façades facing in different directions at the corner. This allows the rooms exposed to noise to be ventilated via the quiet side. The long building length facing the noisy Gutstrasse requires an additional measure: two-storey laundry rooms and additional uses such as home offices, music and playrooms create an attractive inner neighbourhood. The small apartments are grouped into communities of 12 units around the shared infrastructure.

Bundeswehr High-rise, Bremen , 2019

  • © Architektur: Duplex Architekten, Visualisierung: Ponnie Images

The Bundeswehr high-rise building in Bremen’s Bahnhofsvorstadt district is situated in an inner-city location, but is surrounded by main thoroughfares and thus literally washed around by traffic. Our design modifies the current situation of the solitary high-rise building into an urban ensemble of clearly defined street and courtyard spaces. The vertically structured high-rise building is complemented by a horizontally structured plinth. A very narrow, ring-shaped building, which encloses a courtyard of maximum possible size, surrounds the existing high-rise like a bracket without changing it structurally. This creates an inner courtyard that screens off traffic noise and creates a quiet, green internal world. The residential courtyard serves as a lively centre and meeting place for the complex. A variety of playgrounds, recreational and communal areas are created. The symbiosis of both buildings results in an identity-forming ensemble that can assert itself in the heterogeneous urban environment. At the same time, the striking high-rise building remains both recognisable and functional.

Areal Rietwisen, Elsau , 2019

Topography and water are the most striking landscape parameters of the site, a dialogue between tranquillity and flow, including the flow of traffic. These characteristics influence our urban design for the Rietwiesen project in Elsau. In the heart of the meadow landscape is the quarter’s square with a large fountain and play area, which is embedded between the ground floors that attract the public, such as the community centre, the shop and the studios. The day nursery is located near the new community playground with a large climbing structure. The Wiesenplatz is situated in the immediate vicinity of the Riedstrasse as a communicative bridging place to the community of Elsau. Different public open spaces are designed to create places with different atmospheres, where the most diverse forms of living, working and dwelling are given a natural point of reference and location. The open spaces are closely linked to each other by loose spatial sequences, thus achieving an intensive mixing of the residents in their everyday activities. The different building types ensure a varied repertoire of forms of living for different ways of life. Varying degrees of privacy are offered. Contrary to the predominantly public outdoor spaces, which provide for activity in the quarter, the residential corridors of the houses, as semi-private living and circulation areas with adjoining additional uses, such as washroom, music room or craft room, serve the house community. The loggias are the private retreats of the flat-sharing communities.

Beiersdorf is restructuring its factory premises in Hamburg-Eimsbüttel to make the company’s headquarters fit for the future, both in terms of architecture and organisation. The concept reverses the current situation of the closed perimeter development: The new residential quarter opens up and interlocks with the adjacent urban network of the Eimsbüttel district. A large square in the centre of the residential area serves both the new residents and the neighbours from the district as a lively, urban meeting point. As an urban counterpart to the Park am Weiher, it creates identity and links the existing with the new. Green paths and differentiated courtyard layouts create a high quality of living. The size and cubature of the new buildings are based on the nearby block structures dating from the Gründerzeit period. The result is a breathing perimeter development, which is formed by the public intermediate space, opens up towards the edges and interlocks with the urban and green spaces. Based on the building type of the Hamburger Burg, the spatial expansions create varied sequences in the public space, provide insights into the depth of the residential blocks and enable good lighting conditions in the apartments.

‘Togetherness and coexistence’ – great importance is attached to living together in Burkwil. The centre is the ‘village square’, which is surrounded by the buildings and serves as a sheltered yet open place where people can both meet each other and spend some time: a small cobbled square with a fountain and a bench in the shade of a beech tree. All paths through the quarter converge at the ‘village square’. The houses are accessed centrally via the traffic-calmed ‘village road’ and the shared, semi-private arcades. These connecting arcades separate the public from the private space. Around 100 residential units for up to 180 people of different ages are to be built on the 19,000m² site.

Rempart des moines, Brüssel , 2019

The redevelopment of „Rempart Des Moines“ is a unique opportunity for Bruxelles downtown area to embrace diversity and integrate within the same gesture different city aspects. The main intention of the project is addressed to develop an heterogeneous housing offer, capable to react to the complexity of the context. We choose to produce diversity within the project creating a multitude of situations: from living on the ground floor or at the treetops level, shared gardens or urban „Piazza“, narrow streets and common rooftop terraces. The connection between house scale and city scale plays a crucial rule in the project, those intermediate spaces such as courtyards, streets, terraces and community rooms generate proximity and belonging of people to their neighborhood. The project uses density as the essential quality for urban life. This proximity offers the opportunity to create a place for people establishing contact between neighbors and neighborhood. Main topic of the program is to develop 340 social and affordable apartments, together with various public or common functions: a public Sports Hall, seven Community rooms for the neighborhood inhabitants , a Kindergarden, an Old peoples home.

New Replacement building Kalchbühlstrasse, Zürich , 2019, 2nd prize

For the construction of a new replacement building for the Wohn- und Siedlungsgenossenschaft Zürich (wsgz) in Wollishofen, we are looking for a distinct urban figure that blends into the context without being too conformist with the existing neighbouring developments but instead conveys an independent and self-contained sense of serenity. The new building is finished with a smooth façade towards the street and interlocks with the green space via rucksack-like projections at the back. The beginning and end of the row are developed from the context, so that the southern end is designed as a pointed ‘nose’ and the northern end as a ‘head’. The building, which is mainly perceived in a longitudinal movement, is thus given two characteristic and recognisable ‘faces’ that will give the place a new identity.

A prominent, curved external staircase leads to the distinctive, planted arcades, which provide access to all the apartments. The green, very deep terraces serve both as access areas and private outdoor spaces – a “garden arbour” for the residents. The occupants themselves design and cultivate their “front gardens” so that the various plantings create a colourful façade impression. A system of green trellises and curtains forms the actually visible façade, providing sufficient privacy and, at the same time, solving the solar protection issue. The apartments are accessed as if through a greenhouse. The architecture is only the background, while the façade of the building literally grows through the appropriation by the residents. Therefore, the structural façade can be inexpensive and simple. The floor plans have been optimised so that a circulation area is no longer required. As a result, the apartments, some of which are very small, have well-proportioned and spacious rooms.

Housing Development Am Lichtenauerweg, Hamburg , 2018, 1st PRIZE

We propose an open and permeable residential development as a strong and at the same time distinctive urban figure. The rows of houses meandering on the north-south axis open up to the north with residential courtyards, while the green courtyards are oriented to the south. This allows a clear view of the landscape from almost every apartment. The new estate is characterised by a gentle height differentiation from the south to the north and adequate densification in the heterogeneous quarter. The three- to four-storey building volumes make reference to the row structures of the existing neighbouring development, but create more clearly defined exterior spaces. A variety of defined open spaces is decisive for a high-quality living environment. They create room for neighbourly communication and maintaining social contacts, but are also intended to provide opportunities for retreat and security. With a versatile sequence of outdoor spaces, our design creates a varied quarter for the new residents.

Housing estates of the 1950s to 1970s, Hamburg , 2019

  • © Hamburgisches Architekturarchiv

In the 1950s and 1970s, the Hamburg housing market was under great pressure. It was primarily cooperative housing companies that provided answers to the model of the respective decade, from the structuring concept of the structured and loosened up city of the 1950s to the model of “urbanity through density” of the late 1960s to the early 1970s. The estates of these decades are characterised by a low building density, unsatisfactory open spaces, and a need for modernisation of the existing building stock; from today’s perspective, they call for restructuring and upgrading. The aim of the procedure is to develop approaches and ideas for 14 Hamburg housing estates in close cooperation with the Hamburg housing cooperatives. Experimental and innovative approaches to solutions should be generated that enable discussion and provide transferable starting points in order to generate added value for the city as a whole and to show development options for the quarters dating from these decades.

Petit île, Brussels , 2019

The Petit Ile project in Brussels comprises a total of 397 apartments, 13,500 square metres of shops, studios, office space and two schools. The design of the quarter was developed by Multiple, pool, AAA and Duplex Architekten, resulting in a wide variety of different residential typologies on the site, which meet the various requirements for contemporary living. Although the new quarter represents an urban ensemble with a high density, the rising buildings as solitaires convey a certain permeability. The edge of the block is framed by the continuous base level, the urban spaces are clearly defined. Uses oriented towards the public enliven the ground floor zone. The privately used courtyards serve as meeting points and as the centre of the block, the green gardens on top of the buildings invite common occasions.

Swiss Embassy, Addis Ababa , 2018

In the garden landscape that surrounds the building on the embassy grounds the new message is set as a sculptural volume. The building opens up in certain points, allows exciting insights and views, and mediates between the intimate inner courtyard and the garden. The exterior space is clearly laid out (security) and nevertheless creates very different atmospheres for the respective building sides and uses. The compact building volume makes it possible to preserve many of the trees on the site, two are worthy of protection and therefore replanted. Due to the pulpit-like vertical extension, the building is also visible from Jimma Road and sets a striking symbol towards the city. Bringing together various embassy functions in one building directly supports contact between the individual embassy departments. The heart of the building, the green inner courtyard, invites both to focus and to exchange ideas. Meetings are encouraged by the all-round circulation paths and internal stairs. Orientation is easy due to the clear building structure. The embassy’s garden is seen as a kind of showcase for Switzerland’s virtues and interests as well as for its commitment to Ethiopia. It makes statements on the topics of understanding nature, cooperation, and cultural landscape. The climate, which is conducive to horticulture, as well as the obvious expertise of the gardening staff is appreciated.

Buchholzer Grün, Hannover , 2018

The new residential estate “Buchholzer Grün” with its central green space is accessed via street spaces resembling village greens. These are lined with elongated building blocks in which a wide variety of building types and forms of living are developed. Cluster 4 in the southwest comprises a 5-storey apartment building with subsidised housing, a 4-storey building block with condominiums as well as 10 terraced houses on the opposite side of the “village green”. The design idea is based on the development of a common leitmotif for the three buildings. This idea is primarily expressed in the façade design, but it can also be found in the floor plan typologies. The elongated 4-storey building is accessed from the “village green” via three staircases. It is characterised by a very efficient layout with spacious 1.5-3-room condominiums. For the most part, the units are planned as “push-through typologies” oriented towards two sides. Based on a system with uniform axial dimensions, 10 terraced houses are provided in four building units of varying sizes ranging from 100-160 m2 with 3-6 rooms. The efficiently organised interiors of the apartment buildings are enveloped by vivid façades.

Wydäckerring residential development, Zürich , 2018

The new building project is divided into four residential buildings, which together with the future school building enclose a spacious courtyard on the urban site. The clear definition of the four separate building volumes in the urban planning context ensures the desired permeability to the quarter’s green connecting axis, the Triemli footpath, and the other adjoining open spaces. The space-forming element of every apartment is the “Enfilade Room”, a generous linear connecting space that links all areas of an apartment like a spine. Due to the clear positioning of the Enfilade Rooms in the large building volumes, the apartments are oriented towards at least two sides and offer a variety of views. With its orientation, the Enfilade Room emphasises a wide view despite the proximity of the buildings to each other and thus creates added value for the apartments oriented towards the space in-between.

The underlying design principle is heterogeneity. Based on the diversity of developers, authors, and urban context situations, we look for a common denominator that gives the ensemble a design unity: Diversité dans l’Unité! The focus is not only on the block or building structure, but on the urban interspaces, i.e. streets, alleys, and squares. Across construction sites, individual design rules apply to these “strips”. In this way, their specific characteristics can be strengthened. It is required that the architectural expression of all buildings must relate to the area’s industrial past. The design means can be freely chosen and can be derived from completely different themes, e.g. from materiality, volumetry, construction, physiognomy, or the colour scheme. Each building site must make a contribution to the district, such as day-care centre, plant garden, or workshops.

New Replacement building Lacheren, Schlieren , 2017, 1st prize

The site is located in the Lacheren area on the northern edge of the town Schlieren. The quarter is characterised by two- to three-storey residential buildings. The two replacement buildings with 35 apartments harmoniously integrate into the existing layout of the quarter and the northern development. Due to the positioning in the urban context, almost every apartment has two sides with the greatest possible variety of character: on the one hand, the strongly structured, harder back facing Limmatstrasse, on the other hand, the quiet side facing the courtyard. The spatial structure is geometrically dissolved into free forms by means of wall slabs, while the individual rooms remain rectangular and static. The architectural expression of the building is manifested in the duality of the façades: The street façade is designed as a compact system with continuous strips. The slightly golden shimmering glass stripes create a subtle play with the classic themes of horizontal façade structures. Analogous to the horizontal elements on the north side, the vertical structuring elements are designed as panes coated with golden fleece on the rear. These serve to generate solar energy, but, above all, they are design elements which, depending on the incidence of light, lend the courtyard a different atmosphere at any time of day or year.

ITU Headquarters, Geneva , 2017

Connecting the world starts with in-house communication. Internal exchange is a major challenge for a company with 700 employees. The core idea of our design is a central, multi-storey space that enables orientation, connections, and eye contact between the various departments and workplaces. A wide range of special rooms such as a piano room, a workshop, a prayer room, a fitness room, or the outdoor terraces provide different meeting places and cause people to move between the storeys. Ultimately, the aim is to create a working environment where both concentrated work and a simple and relaxed exchange of know-how among all employees is possible.

Heidelberg Convention Centre, Heidelberg , 2017, honorable mention

This building is intended to become a meeting centre of regional and international importance on the former “wasteland” behind the station, thus creating an identity-building focal point for the new Bahnstadt district. The distinctive cubature, which is characterised by dynamic lines, lends the new conference centre a solitary character and thus does justice to its leading role in the Bahnstadt. Typologically, it sets an urban counterpoint to the high-rise buildings of the hotel on the station forecourt and of Schiller International University. The extra-high storeys create a unique scale, which, in keeping with its function, sets the building apart from the surrounding residential and office buildings. Towards the southern station square, the appearance of the new conference centre is welcoming and open. A striking recess in the building cubature creates a prestigious forecourt in front of the main entrance, which thanks to its clear urban layout extends the station square across the street. To the west, the conference centre forms a clear boundary to the green area of Zollhofgarten.

On the 42,000 m2 site of a former glass factory in Bülach Nord, 550 new apartments will be built for around 1,700 residents between 2018 and 2022, plus 27,000 m2 of commercial space. Altogether, the ensemble comprises 20 mainly 6-storey buildings, including a hotel, a retirement home, a high-rise residential building, a commercial building, and an office building. The high urban density calls for special architectural measures. The overall concept therefore focuses on the meticulous design of the urban outdoor areas. As a point of contact between the buildings, they will determine neighbourly cohesion. The urban planning concept is based on a system of radial streets that are, as with a linocut, cut out from the building mass. At various intersections, squares are created whose character is largely determined by the use of the adjoining ground floor. A lively and intact quarter is based on the balance of diversity and unity. Its unmistakable urban pattern, the “urban fingerprint”, gives the Glasi Quarter a recognisable identity. At the same time, it provides a stable framework for diversity. The special feature of the architectural design is that the individual buildings subordinate themselves to the leitmotif of the overall concept, but at the same time, develop characteristic peculiarities in their individual expression. A wide range of residential typologies opens the Glasi Quarter for different user groups - for young and old, for couples, singles, and families. Special solutions are also available, e.g. for living in old age or large shared flats for patchwork families living together. In addition, a substantial proportion of commercial use is planned. Living and working take place in the immediate vicinity and ensure a healthy mix of different uses.

The sculptural building comprises various floor plan typologies for today’s urban residents. The studios share a common patio. The apartments with 2½, 3½, and 4½ rooms are characterised by attractive visual connections across the apartments. The bathrooms are situated along the façade and invite to relax. By including the bays, all apartments are organised around the corner and benefit from a two-sided orientation. The façade of the distinctive building is clearly structured by a horizontal division into base area, standard floors, and attic floors. The generous glazing on the ground floor opens up the building to the surrounding streets and provides ideal conditions for uses close to the public. Balustrade strips of varying heights made of polished, terrazzo-like artificial stone, window frames with anodised metal panels, and fine metal railings cover the building as a braided envelope, lending the façade a high-quality, almost textile look. Due to the spatial depth of the façade and the fine detailing, the impressive building volume nevertheless appears elegant and light and appropriately blends in with the cityscape.

In the north-east of Basel, on the site formerly used as a freight station, the Erlenmatt Quarter is being built, a lively district providing a high residential quality for all strata of the population. A multifaceted coexistence and community of lifestyles and neighbourhoods, complemented by public, social, and commercial uses. The buildings and facilities on the site are planned, built, operated, and renewed in a resource-saving manner.

The new building adjoins the silo building constructed by architect Rudolf Sandreuter in 1912 to the south and joins the row of buildings along Signalstrasse. Based on the feasibility study decided in 2013, a student residence for 99 inhabitants with commercial use on the ground floor was built here. The hostel is operated by the Association for Student Housing (WoVe), which provides students with functional and inexpensive accommodation. Students will live in 16 shared flats with 4 to 7 residents each. In addition, 3 separately accessible 1.5-room gallery apartments are offered.

The flats are grouped in two wings around the common heart of the complex, a semi-public courtyard on the first floor. This can be reached via a staircase from a public passageway running straight through the building. The unroofed courtyard is 7.80 m wide and over 50 m long. The apartments are accessed via an open staircase, arcades and footbridges that span the courtyard. In front of the entrances to the apartments and eat-in kitchens, the circulation area is expanded into a lounge area. The use of these open spaces enlivens the courtyard and makes it a place of encounter and communication.

Buchegg Estate, Zurich , 2011–2018

In 2010, the Waidberg building cooperative decided to demolish the existing 1930s housing estate and to replace it with a new building. A competition procedure was initiated for this purpose. The topographical col Milchbuck - Bucheggplatz is a high-quality residential area with a homogeneous development structure, which is divided by a main traffic axis. Three angular buildings occupy the perimeter with a minimal footprint. The buildings accompany the streetscapes along Hofwiesenstrasse, Rötelstrasse, and Seminarstrasse; typical local building lengths are thus created. At the same time, the houses form a distinctive appearance towards Bucheggplatz. By moving away from the building line, the head building focuses on the centre of Bucheggplatz and already strengthens its presence in its current state. The noise pollution affecting the site becomes a design generator. The development of the façade is minimised, creating an urban street façade towards the noisy outside area. More public spaces such as kitchens, extra-high dining rooms and stairwells enliven the street fronts and form a hard “back” that protects private living areas. The floor plan is twisted to avoid direct views into the apartments opposite and to create a feeling of expanse. Towards the south, the apartments in front of a large, contiguous open space shielded from the noise of the streets open up to the expanse of the city.

The guidelines of the master plan demand strong, traditional urban planning references, while the intended uses rather require identity and independence. Eleven semi-public courtyards and distinctive streets penetrate the Limmatfeld, while at the same time the residents’ need for individual retreats must be taken into account. The project reacts to this starting situation by arranging the five buildings of the BEP cooperative around a maximum sized shared courtyard. Without causing a hard break, the public “outside” is juxtaposed with a semi-public “inside”.

More than living, Zurich , 2009–2015

On the Hunziker Areal in Zurich, a total of 450 apartments, shops, restaurants, workshops, artist studios, day nurseries, and a guesthouse have been developed. Our vision was to create a piece of city instead of an estate. Urban density is required where squares, alleys, and green zones determine the qualities of the public space. An exciting sequence of outdoor spaces and public-oriented uses on the ground floor invigorate the quarter. In addition to the wide range of common rooms, individual retreats are also becoming increasingly important. It’s exactly this tension that makes up the special feature of this project: on the one hand, security and privacy and, on the other hand, the wide range of opportunities to be part of the community. On the urban planning level, it is the interplay between development and open space elements such as paths and squares; the counterpart in the apartments is the interaction of common rooms and private areas.

Within the scope of a study assignment, proposals for the conversion of the site of the former Rüttimann furniture factory in Siebnen are developed. The buildings on the site were built between 1880 and 1980 and are now vacant. Some of the buildings and the skywalk that crosses the cantonal road today form an ensemble that has a high identity-forming character for the town. Mainly residential use is planned, next to it a smaller part for service and commercial uses.

Zukunft Wohnen (Future of Housing), Cologne , Since 2015, 1st prize

In a workshop procedure initiated by the City of Cologne, ideas were sought for urban re-densification and new housing concepts. For our project in the lively district of Cologne-Sülz, we are focusing on four fundamental areas of inner-city re-densification:

Adequate densification. Gentle increase in height through the addition of one full storey and densification inside the block edge development. Instead of FSI and attic regulation, a three-dimensional outline is defined, which determines the maximum building volume.

Revitalisation of the urban space. For the overriding interaction of the block edge and the common scale, the expression has to consider a three-part building structure. Rhythmic design of the street alignments through differentiated openings, materials or colour schemes according to the principle: “same same but different”. The assignment of public uses at the intersection and in the workyard is decisive for the character of the urban locations and is therefore binding.

Activation of the courtyards. Revitalisation of the inner courtyards through differentiated outdoor areas such as the family garden and workyard. User- and location-oriented appropriation through self-organisation and participation for high resident identification, long-term tenancies, low fluctuation, solid neighbourly integration. Identifiable presence of the rear buildings and commercial areas through distinctive courtyard entrances.

Demand-oriented themed houses. Creation of novel, innovative and demand-oriented, not only standardised housing models, as a contemporary response to social developments (family housing, senior citizens’ housing, cluster housing, rentable additional rooms, outbuildings); integration and inclusion of groups with special needs such as single parents, senior citizens, etc.

Roselius-Allee residential quarter, Bremen , Since 2016, 1st prize

The main objective of the design is to give the entire area an identity-building spatial centre. We are developing a central square that is situated slightly asymmetrically on the site’s north-south axis. Eleven elongated, two- to three-storey saddle-roof houses providing 105 residential units with south-facing orientation are positioned at the front of this square. Due to their diverse gable sides, they form a lively and diverse line of façades on the square. The clearly designed green centre offers play and recreation opportunities for all residents. The asymmetrical arrangement of the square within the overall complex allows an optimal connection to the southern access road as well as a subsequent development of the northern or north-eastern area.

New "Verteilzentrale" Quarter, Pratteln , 2017

An attractive and lively quarter is to be developed on the site of the old Coop distribution centre (“Verteilerzentrale”), located directly next to the railway station in Pratteln. The program includes various residential uses, commercial use and a new school complex. Ten teams were invited to participate in the one-step study.

Suurstoffi Zug, Rotkreuz , 2017

The almost completed “Suurstoffi” quarter is located in the immediate vicinity of Lake Zug, embedded in an impressive landscape and well connected due to its proximity to the Rotkreuz railway station. For the final stage, we propose two buildings of different sizes within the perimeter, which are spatially offset from one another along their longitudinal axis. The volumetric design of the two buildings differs just as much as the appearance of their façades. The longer volume of the two takes up the alignment of the neighbouring building and continues it in a straight line along the park. On the one hand, this simple urban-planning positioning creates a clear, adequate front facing the park, which has an impressive appearance due to the significant recesses on the upper floors, and on the other hand, it forms an appropriate forecourt towards the road located north, which represents a constructive connecting point for a possible further development of the area in this direction.

Quarter on Moosrosenweg, Hamburg , 2017, honorable mention

The aim of our design is to give the entire area a spatial centre. The Moosrosenweg is the backbone and identity-creating centre of the new district. We propose a dense, urban-looking quarter with clearly defined street, square and courtyard situations. The sizes and cubic volumes of the new buildings are based on the block structures of the pre-war period, but at the same time seek a dialogue with the existing buildings. This creates a “breathing” block structure that is formed by the public space in-between, opens up to the edges and interlocks with the green areas. The result is a sequence of different squares and streets. The entrance to the quarter is flanked by three head buildings, which enclose a lively forecourt with public uses and catering facilities, located in second row and thus protected from noise.

Legler Areal, Glarus , 2017

The Legler Areal is an industrial ensemble dating from the 19th century. It is located in the Glarnerland region in the Swiss Alps, about an hour’s drive from Zurich. The industrial weaving mill was founded in 1856 by Mathias Legler. Around 1910, a modern spinning mill was added, which was in operation until the 1960s. The weaving mill, by contrast, was finally closed in 2001. Since then, most of the buildings have been vacant. In this study, we examine the possibility of a co-working retreat on the Legler site. The vision is to create an inspiring place in a quiet environment shaped by nature, where modern forms of work and contemporary relaxation as well as exchange and retreat are all equally accommodated. The Legaler Areal should become the ideal place for digital nomads, artists, company workshops, events and celebrations, yoga retreats but also for outdoor enthusiasts and weekend tourists.

Windisch Recruitment Center, Kunz spinningmill Windisch , 2017

Within the scope of the site development of the Kunz Spinning Mill in Windisch, a usage study for assisted living was carried out for the Rohn building, which was previously used as a recruitment centre. The building was completed in 1960 as the last building of Roland Rohn’s spinning mill ensemble. Integrating the new uses into the existing building structure only requires minor modifications. There is space for 48 rooms along the north and west façades. Six residents each form a living group, which is assigned its own common room. In addition to group accommodation, areas for workshops, staff and administration, utilities and common rooms are planned. The gym in the basement is to remain.

City Entrance Slüterstrasse, Rostock , 2017

For centuries, the city gate “Petritor” shaped the silhouette of Rostock’s old town. Its demolition destroyed this harmonious ensemble and thus a piece of the city’s historical identity. In order to close this huge gap in the evolved city structure, the construction of a new city gate has the task of restoring the historical structure of St. Peter’s Church, city wall, and the small townhouses of the old town, which are staggered on the slope, with contemporary architecture. The city gate once again plays a central role in the newly created urban ensemble with its strong cubature of reddish brick, which takes up the proportions of the original Petritor. As in the past, only the shape of the roof is varied. The closed brick envelope dissolves into a filigree network of brick pillars and precast concrete lintels along the east façade. This inviting gesture shapes the unmistakable appearance of the new Petritor at the eastern entrance to the city. The wide passageways and the large loggia on the upper floor are part of a façade composition of differentiated openings that plays with the themes of security and transparency. The office and residential buildings are constructed in the style of Rostock’s townhouses as simple plaster buildings with punctuated façades.

Weissensee Quarter, Berlin , 2016, 2nd prize

The new Weissensee Quarter is a very special, small and urban world. The location between two cemeteries and the loose housing development as well as the school calls for an urban design with strong internal relations. The precise positioning of eight residential buildings of very different sizes allows both the formation of an identity-forming community centre and a differentiated reference to existing urban structures. Interspersed smaller structures and pavilions complement the urban figure, which is new in its context, and break up its scale. A public road connection runs through the site. The common space is structured by means of a sequence of square-like situations. The newly created outdoor areas connect with the existing green space and thus strengthen the overall context, which is strongly shaped by nature. On the property, the public thoroughfare interlocks with public and private green spaces. The ground floor is designed as a primary community-building zone. The exterior space not only connects with the network of public paths—the houses themselves also interact with the sequence of outdoor spaces.

Canteen Comprehensive School, Greven , 2016

Embedded in the new school park, the canteen is to assert itself as an independent building in a heterogeneous environment between the school buildings and the housing estate of single-family homes and, at the same time, create a spatial termination to the north. We propose a light pavilion with a distinctive roof, which has its own identity and simultaneously in its expression refers to and reinterprets the large roofs that are characteristic of Greven. The exterior and interior merge, the roof structures the building and defines hierarchies: underneath the “big roof” is the central dining hall, which extends across niches, for example the stage, up to the façade. The serving functions such as kitchen, storage and technical rooms as well as toilets are grouped around the hall, while the foyer and entrance area are oriented towards the school. The canteen as a meeting place for the school community is conceived as a market hall where pupils can meet for a meal and exchange news and information. The intention is to spend the lunch break here in a relaxed, secure atmosphere. The bright dining hall with its calm, clear ambience also offers the school a versatile room for celebrations and events.

Marckmannstrasse, Hamburg , 2016

The quarter on Marckmannstrasse in Hamburg-Rothenburgsort is a heterogeneous ensemble of post-war residential buildings and low-rise warehouses. The aim of the design is to create a dense, urban-looking quarter with clearly defined street, square, and courtyard situations. The size and cubature of the new buildings are based on the block structures of the pre-war period, but at the same time seek a dialogue with the existing buildings. As a result, the building heights develop, on the one hand, from urban planning considerations to frame the street space and, on the other hand, from reacting to the existing building opposite (staggering). Clearly defined public outdoor areas as well as attractive inner courtyard situations for semi-public and private use are laid out. However, we avoid reconstructing the typical closed block edge of the Wilhelminian period. The solitary character of the independent, compact building complexes remains clearly recognisable. At the same time, the permeability of the structural arrangement generates numerous visual references between the buildings, connects them with attractive open spaces and thus unites them to form a strong, identity-generating urban ensemble.

Creative Blocks 82, Hamburg , 2016

The public uses along Versmannstrasse and the pedestrian axis are decisive for the character of the urban planning location. They enliven the urban space and interact with it. The workshops located along the façade, the restaurant facing the waterside, and the bar attract visitors to the heart of the manufactory, a place with an impressive atmosphere for presentations and encounters. The inner courtyards and roof terraces are made accessible to the residents as private outdoor spaces. The visual connection of each apartment to the water and thus the orientation towards the south and the view was the main leitmotif for the organisational division of the buildings. The various buildings have clearly recognisable typologies: co-living with spacious and well-positioned meeting and circulation areas, common areas grouped on the ground floor and oriented towards the city as well as small apartments turned towards the harbour, subsidised residential units designed as a noise protection type with arcade access and robust, flexibly usable room-to-room principle, and condominiums with a generous façade structure and a flexible room layout.

Canteen Turmweg School, Hamburg , 2016

Nestled in a park-like setting with old trees, an ensemble of detached buildings constitutes the primary school on Turmweg. In this heterogeneous architectural environment, the new canteen is to assert itself as an independent structure and simultaneously reconfigure the schoolyard towards Hallerstrasse. We propose a clear, hall-like building that acquires its own identity through a distinctive roof landscape. The simple, elongated volume blends unobtrusively into the surrounding buildings. Only the view to the gable façades brings out the exciting, characteristic silhouette of the roof, whose dynamic movement accompanies the access route from Hallerstrasse to the schoolyard. The roof structures the building into three recognisable functional areas—the “supply area” on Hallerstrasse with kitchen, delivery and ancillary rooms, the extra high dining hall in the centre of the building, lit by a lantern-like band of skylights, and the covered entrance area in front of the building, which opens onto the schoolyard. Following the idea of a market hall, the new canteen is conceived as a meeting place for the school community, where pupils meet for a meal and exchange news and information. The canteen also serves as a meeting point during breaks, allowing activities under the large canopy even in bad weather. Here, parents pick up their children after school, and people meet for a chat.

Different living in old age, Oberrieden , 2016, 2nd prize

The tranquil atmosphere of the “Winkelhalden” residential development is to be disturbed as little as possible by the new buildings. The heterogeneous urban planning approach divides the entire construction volume into acceptable units. The new silhouette leaves enough room for the neighbouring buildings so that their lake view is only marginally affected. Active, self-determined living and habitation in old age is defined by the choreography of public uses throughout the complex. A bistro as well as studio and music rooms are located around the “Piazza”. The networks of paths through the outdoor space ties the whole ensemble together. The landscaping concept for the estate is a nature-orientated design that uses landscape elements to create an exciting outdoor space. The houses are accessed via the common, semi-private loggia layer. The continuous, open pergola turns into a meeting place. Due to the hillside location, each house can be entered on two levels: from the upper section of the slope, with an outdoor space to be designed in a participative manner, and from a side entrance on the lower level, with the assigned common room and launderette. The structural concept of the lever bar system allows several apartments to be combined into larger units. The individual living units are conceived as a modular system.

Living at the Hartenberg Park, Mainz , 2015, special mention

Located on the Hartenberg plateau, the property extends deep into the green park. The buildings follow this movement. Folds and protrusions anchor the buildings and create squares and courtyards. Specific omissions and recesses take up the granular layout of the surroundings: the building volume concentrates on seven compact row buildings typical of the area, and two large connected residential courtyards are created inside. Contrary to the surrounding park, the character is bright and open. Loosely scattered groups of trees and a coherent network of paths are the few but atmospheric structures that characterise the place, structure the elevation of the folded walls and generate spatial depth. Apartments with extra high kitchen areas benefit from the view to the park and the inner courtyard. The neighbouring buildings C&D are laid out with 2-3 residential units sharing a circulation core, so that the resulting apartments are oriented towards 2 sides at least. The buildings E, F & G are very efficiently organised with one core serving 3-5 residential units. Diagonal visual connections create exciting sequences of rooms that make the apartments appear larger.

“The Hunziker Areal was realized in 2014/2015 as a pioneering building and housing project. It is a beacon project for non-profit housing construction and is committed to the goals of the 2000-watt society. The exhibition room at Genossenschaftsstrasse 13 has dedicated a multimedia exhibition to this process since 2007. It is also considered a living archive and is to be continuously developed and complemented. The exhibition acquaints visitors with the guiding principles of the “mehr als wohnen” cooperative building association: How do you build for the 2000-watt society, and how do you live in the energy-saving buildings? How do residents of the quarter participate? Text, image, and video contributions in which residents, planners, and contractors have their say address these questions. The exhibition features a wide range of publications, first-hand reports, media articles, and background information on non-profit housing construction, cooperative projects, architecture, and urban development. An exciting fund for students and specialists, but also for those interested in general. The exhibition can be visited during the opening hours of the reception.” (More than Living)

Cities Connection Project, Barcelona–Zurich , 2016

  • © The Cities Connection Project

The “Cities Connection Project” (CCP) is a project of architects Nicola Regusci and Xavier Bustos from Barcelona, which creates synergies between architects, cultural institutions, authorities, and universities in European cities. With Barcelona as a meeting point, the focus is on the organisation of exhibitions, conferences, and other “connections” in two European cities that are distinguished by their special architectural and cultural traditions.

Guest House University of Hamburg, Hamburg , 2015

The new guest house of the University of Hamburg is to be built in the immediate vicinity of the listed Museum of Ethnology. The triangular site is located in a high-quality urban conservation area, which was severely affected by destructions during the Second World War and planning mistakes in the post-war period. The new building therefore plays a key role in the effort to strengthen the prestigious appearance of the Wilhelminian style district, part of which is under a preservation order. The urban figure we propose occupies the northern corner of the property along Feldbrunnenstrasse and Mollerstrasse with a distinct gesture. As a result, the new building keeps an appropriate distance from the Ethnological Museum and creates a spacious garden with a high recreational quality in the southern part of the property. The building is structured by deep courtyard-like recesses, similar to the typical urban principle of the Hamburg “Schlitzbauten” (multi-storey residential buildings with a T-shaped ground plan and lighting slits on the rear side), so that its volume adapts to the proportions of the small-scale villa structure of the neighbouring development.

Am Mühleberg, Berlin , 2015, 3rd prize

The site “Am Mühlenberg” was developed in the 1950s in the typical style of post-war modernism. We modify the existing structure with the help of adaptors to achieve a new urban ensemble with clearly defined streets and courtyards. The existing buildings remain legible and functional. The heights of the new buildings are oriented by the adjacent houses or result from urban planning considerations to define the street space. At the same time, clearly discernible outdoor typologies are created. These include rather introverted but walk-through courtyards of different character, a continuous alley system, partly car-free, partly as residential paths with visitor parking spaces, and a sequence of distinctive public micro squares.

Department Store Façade Design, Kiel , 2015

The new department store is situated in a prominent inner-city location. With the planned restoration of the “Small Kiel Canal”, the building will not only flank Berliner Platz but also form an important part of the inner-city silhouette along the new waterway. We propose a high-quality, prestigious, clearly structured façade design that focuses on the north façade facing Berliner Platz. In order to clearly define the square in terms of urban planning aspects and to make the building’s façade facing the square clearly discernible as the main elevation, we have dispensed with the rounded cubature of the present planning status. Instead, an arcade zone is created on the ground floor at Berliner Platz, which emphasises the show facade of the department store and creates a generous entrance area as a transition between the public square and the new second main entrance to the store.

In the summer of 2015, around 1,200 residents moved into the thirteen houses of Project N°1 of the “Mehr als Wohnen” building cooperative. “With Other’s Eyes” is a film project with which we accompanied this historic moment: From close proximity, we watched the emerging neighbourhood grow. Shortly after they moved in, we communicated in writing as silent directors with the residents of “our” houses over a period of six weeks. In the form of directing instructions, we asked them to explore the various locations of their new home by filming them. They are the actors in this film: protagonists and cameramen at the same time (click here for the trailer).

For the film premiere at Architektur Galerie Berlin, a pop-up cinema was built instead of a museum presentation. The two synchronised projection rooms allowed a real cinematic experience, where all attention was focused on the film. The foyer in-between featured two works by Piet Hein van Eek. The Dutch furniture designer arranges seemingly worthless material into artistic objects of utility. Lamp and counter were produced especially for this exhibition and are just as much “serial unique pieces” as the professionally cut raw material in our participative film project.

Mythenquai, Zurich , 2015

Along Mythenquai, the massive base level with its commercial uses is the dominant element. The common base encloses two 6-storey filigree residential buildings like a bracket. The differentiated building heights and the projections and recesses of the residential levels add a rhythm to the street profile of the elongated building volume, as is typical for the façade design of many industrial buildings along Mythenquai. The horizontal division into base, upper and attic floors also continues the design canon of the surrounding buildings. In order to provide access to the lake through the long building volume, the division of the upper floors into two clearly separated structures is another striking design element of the western façade. On the lake side, the building appears to be a staggered ensemble, which, depending on the viewpoint, seems to consist of individual structures. At the same time, the staggered lake façade creates an enlarged façade design that makes it possible to provide every living room and bedroom with a lake view. The positioning of the buildings creates a narrower urban outdoor space towards Mythenquai and on the lake side— also along the entire length of the property—a larger outdoor space for the residents, which visually extends the Savera Park.

Haven Island, Wilhelmshaven , 2015, 3rd prize

In projects involving living by the water, we play with the concept of inner-city density: the vastness of the harbour basin is deliberately given a counterpart of urban spatial structures. Accentuated distribution of densities creates not only connecting bottlenecks but also differentiated open spaces, which are essential to keep a district together. The design is thus a kind of antithesis to conventional residential areas. There are no semi-private backyards, but the greenery, the recreational areas and parks (concentrated and decentralised) are part of the urban outdoor space. The north-south alleys form a network of viewing axes to the sea, while the west-east axes connect the squares scenographically. The “mistakes” in the system or the omissions create small squares and points of attraction. Public life is focused around these spaces and a new quarter full of character and variety emerges. The buildings are dimensioned in a way to allow, depending on the apartment mix, four to six residential units with a shared circulation core. 80% of the apartments are oriented to two sides and overlook both the harbour basins and the squares. In addition, there are tension-filled connections from the corner of the apartments into the alleys and along the main axes.

Artland Grammar School, Quakenbrück , 2015, special mention

The existing urban situation is characterised by the coexistence of different building types—resulting in an unsteady spatial structure without a clear layout. Our design integrates into the one- to two-storey buildings, supplements and reorganises the existing building parts and clearly structures the exterior spaces into public and semi-public areas. “Continued construction” is the central idea of the design, which characterises the approach to the existing building structure of the main and adjoining building in floor plan, façade, and structural concept. The existing building, in which the spacious corridors and long routes are particularly striking, will be gutted and reorganised. The new building adjoins the existing building and expands it with new spatial constellations that give the whole a new identity.

Bauhaus-Museum, Dessau , 2015

The Bauhaus Museum is a filigree, three-storey building on the north-eastern edge of the city park. Following Dessau’s old city structure from before the Second World War, a prominent location will be newly occupied. With its elongated shape, the building frames the streetscape along Kavalierstrasse and at the same time defines a clear transition between city and park. The differentiated “head of the building” at the intersection Friedrich-/ Kavalierstrasse as well as the slight recess from the street alignment emphasise the new museum as a special cultural place in the cityscape. Thanks to the compact design, the extent of interventions in the park is limited to minor measures that anchor the museum in its surroundings.

Südmole Wine Pavilion, Mainz , 2015

In a newly emerging urban district, the question of identity-forming elements has a very special significance. It is important to create places for sensory experiences, objects that attract people’s attention. At the junction between the North and South pier, the inner harbour and the Rhine, the pavilion rearranges the spaces. By placing the extra high volume, it acquires the necessary weight. Like a lighthouse, it defines the anchor point of the different directions of movement as a new attraction. At the same time, it blends into its surroundings with its partly folded longitudinal sides so that inviting places are created.

Parish Centre, Hamburg , 2015, 3rd prize

The new parish centre merges with the existing building and presents itself as a staggered building volume with a cross-shaped ground plan and autonomous north, east, south, and west wings. With a prestigious entrance along Friedrich-Ebert-Strasse, it develops a new, dynamic silhouette. As a counterbalance to the adjacent small-scale development, the building avoids any suburban fragmentation. It occupies the corner of the site without hermetically closing it off. On the ground floor, a backlit foyer connects the event hall, restaurant, and chapel. A distinction between old and new is only visible at second glance—the inner courtyard with the surrounding cloister unites the building parts into a whole.

University Campus, Potsdam , 2015, special mention

The site of the university campus at the New Palace in Potsdam is located in one of the largest and most important parks in Europe. As part of the UNESCO World Heritage Site, its development is subject to the highest urban and architectural preservation requirements, which can only be met by the best possible integration of the building ensemble to be planned into the Sanssouci Park landscape. We propose the division of the building volumes into several “houses”, which unfold an extensive network of inner courtyards and small squares. The small-scale building ensemble with its finger-like ground plan structure literally interlocks with the surrounding park landscape. The new campus complex is architecturally oriented towards the outbuildings of the palace complex, such as the gardener’s house and the Kaiserbahnhof. Thus, these buildings develop as a reproduction of this building type from individually discernible “houses moved together”. This additive principle provides great scope for expansion and the future development of the university at this location. It is variable in its design form, allows many different uses and can therefore also adapt to future changes in the university operation.

Suurstoffi, Rotkreuz , 2015

“The building on construction site C will occupy an outstanding position in the Suurstoffi quarter due to its height and central location. The aim is that the building not only incorporates this aspect through its form, but above all through its energy concept, which is achieved through an intelligent mix of high-tech and low-tech. Since neither the location nor the view of the building constitutes a unique selling proposition in relation to the competing properties, the building itself must become this unique selling proposition. It is to be clearly recognisable as a residential building by means of a non-monotonous, lively and “green” façade and represent something unique in Switzerland. (Excerpt from the competition brief)

Sports facilities for the 2024 Summer Olympics Kiel, Kiel , 2014

With the Schilksee Olympic Centre, Kiel has proven its capabilities for more than 40 years. The grounds of the former naval pilot squadron in Holtenau give Kiel a promising opportunity for new, urban Olympic sailing competitions—modern, urban, and visionary. Due to further planning, Schilksee can once again become a new Olympic centre—providing an infrastructure that not only meets the requirements of 2024, but also shows future potential. The proven backbone of the entire complex becomes the starting point for the further architectural development: From the boulevard on the second floor, which is open to the east and provides barrier-free access as well as shops, restaurants and an integrated swimming pool, spectators have an excellent view of the harbour area in 2024, without interfering with the athletes’ preparations.

Inselspital, Bern , 2014, 5th prize

The “Herz Dame” project aims at the consistent recognisability of the base volume and ward tower. The construction area is fully occupied, which, on the one hand, ensures favourable conditions for horizontally organised hospital processes and, on the other hand, supports the clarity of the open areas defined in the master plan. The simple, compact structure also offers a good ratio of enveloping surfaces to volume and thus generates an energetically and economically favourable starting position. The central structuring element is a generous space punched out of the base. This internal hall brings daylight all the way to the entrance level and guarantees simple & orientation. Versatile views into and from the building support interdisciplinary communication. The hall is the actual place of arrival and becomes a hub for all patients and visitors of the future Inselspital—which allows or even requires such an expansive gesture to do justice to this significance. At first glance, the Inselspital presents itself to the visitor as an open facility and reveals a controlled transparency that creates trust.

Great Minster, Zurich , 2014

The Great Minster has to meet a wide variety of requirements. Besides its actual purpose as a spiritual meeting place, it is also an accessible landmark affording a generous view, an attraction for those interested in culture and Polke fans from all over the world, as well as an event hall for concerts. Like an instrument that is constantly exposed to different temperatures, it must now be “tuned” in order to create a harmony of the different requirements. We propose a catalogue of measures that can be implemented in modules. After each module, the effect achieved can not only be qualified by means of a scientific analysis procedure, but also quantified. Visitor behaviour, for example, is recorded by temporarily installed cameras and evaluated. The result supports the decision for the respective next step.

Südbahnhof, Hannover , 2014

The distinctive triangular geometry of the site reflects the project’s position as a nucleus between the block edge structure to the west, the industrial zone to the east, and the noisy, prominent railway line in the north. These built structures in the dispersed neighbourhood with atmospheric density characterise the plot. The proposed large form, designed as a block edge development, reacts to this diverse neighbourhood and strengthens the quality of its surroundings with contextual building sections. As a coherent figure, the building maintains a uniform expression and continues the tradition of the local settlement history. The newly proposed volume has the potential to assert itself as a sustainable identity-generating building in this heterogeneous environment.

Development Outline, Stellingen , 2014

At Sportplatzring, in the geographical centre of Stellingen, the spatial densification and the layout of precisely designed public open spaces are to create a place that will become the identity carrier and development engine of the district. Sportplatzring forms the backbone of the urban development. The widening of the road space creates places with specific spatial qualities and further enhances Sportplatzring. On the sports field area, we propose an urban figure consisting of elongated, expansive buildings that enclose these identity-forming places and continue the theme of the square in semi-public inner courtyards. The residential and commercial building on Stellinger Markt plays a special role. Two 175m long buildings are placed along the busy southern part of Sportplatzring, protecting the quarter from noise emissions and constituting the face of the new quarter. The buildings of the second construction phase on the school grounds are also in dialogue with the adjacent building stock. Here, we propose eight detached houses in the park with three full storeys and a recessed penthouse level.

Oberes Murifeld, Bern , 2014

The urban planning pattern takes up the two prevailing directions of the heterogeneous neighbourhood and thus mediates between the residential rows (north-south) on the one hand and the commercial buildings (east-west) on the other. The four-storey building rows allow good passage through the site, their meandering form generates a sequence of squares which become an important means of identification for the residents. Alleys and courtyards alternate, a variety of views from courtyard to courtyard and exciting spatial sequences emerge as you walk through the area in both directions. Access is provided along the east façade, so that on the west side a substantial proportion of private gardens is available for the apartments on the raised ground floor. The eight-storey “towers” create a volumetric anchoring of the urban fabric; they accompany Weltpoststrasse and mark the main entrance to the quarter. They are key points of orientation within the area and offer a good starting position for attractive apartments with a panoramic view.

Urban Living, Berlin , 2013

The property “Am Mühlenberg” was developed in the 1950s in the typical style of post-war modernism. All of a sudden, a group of free-standing housing blocks, which are surrounded by extensive green areas, rises in-between the neighbouring block edge development dating from the Wilhelminian period. The generous but undefined public space between the buildings allows neither urbanity nor privacy to develop and therefore remains largely unused. The existing buildings remain both comprehensible and functional. On the one hand, the project creates new living space within the inner periphery of Berlin and, on the other hand, modernises an “aging” residential area, which will lead to a mixing and rejuvenation of the local population. The size and cubature of the new buildings are based on the solitary character of the apartment blocks. The building heights make reference to the adjacent development or result from urban planning considerations to frame the streetscape. The readability of the existing road network is strengthened and clearly defined public outdoor areas and new courtyard situations are created, where semi-public and private uses are possible.

Conversion of a Silo, Basel , 2013-2016, 1st prize

As a witness of the city’s industrial past, the historic silo becomes the nucleus of the new development in Erlenmatt. A variety of public uses make it the centre of communal and cultural life in the quarter: gastronomy, common areas, local library, cinema, swimming pool, music school, and rehearsal rooms bring people together and have an appeal beyond the neighbourhood. The specific character of the industrial building with its differentiated horizontal layering is maintained and strengthened, vertical circulation and functional rooms are moved to the joint buildings. The central role of the building is also manifested in its relationship to the newly created space. The elegant paving of the square extends to the ground floor hall and blurs the boundary between interior and exterior: an ornamental pattern of asphalt and natural stone slabs is rolled out like a carpet in the exterior. The square becomes a living space, the house becomes a square.

Gastronomic Pavilion ETH, Zurich , 2013, 2nd prize

SBB agrees to transfer a station building / freight shed to the ETHZ for the symbolic price of one Swiss franc for use as a restaurant pavilion. The costs for dismantling, transport, and reassembly are included in the bidding consortium’s quotation. The transferred building is a representative of its time and demonstrates the changes in Switzerland as a technology location: In many places, route optimization, automation, and logistical progress deprive the former station buildings of their original purpose. The goods shed symbolises the networking of ETH, not only with regard to the reference to its original location but above all to the motif of the railway station as a place of arrival and departure. The question of sustainability is almost incidentally answered on a completely different level beyond the label: a second life cycle is given to an inconspicuous functional building that “has already lived a life before”.

ZHAW + Zusammenhalt, Winterthur , 2013

For this complex construction project, we choose an integral approach and see a unique opportunity for transformation. The heart of the “new building” is the reversal of the existing Hall 191 into a courtyard: The roof in need of renovation is removed, the old industrial façades form the internal face of the newly created outdoor space. A place that tells stories of its industrial past. It becomes a meeting place for students and lecturers of both faculties as well as residents and visitors of the area. The second design-generating element is derived from the issue of the interface between university and housing association: An internal lane dissolves the functional separation of the very different uses and simultaneously creates an immediate spatial cohesion. The scenic path along the alley starts with lobby and reception at the street and leads along the entire length of the building until it reaches its end point at the two-storey activity platform. This is also an ideal venue for events—with an attractive view across the tracks.

Mehr als Kunst (More than Art), Zurich , 2010 – 2017

The “mehr als wohnen” building cooperative is developing a new (urban) quarter on the Hunziker site in Zurich-Leutschenbach. Since the building site is a place without evolved structures and its own identity, phase 1 of the art and building project “more than art” focused on the fallow land and the dialogue with residents currently living on and around the site. The team of curators Grillo/Wagner concentrated on temporary participative and dialogical art projects. Parallel to the projects, a blog was initiated, which is maintained by Karin Freitag. The second project phase focused on the dialogue between architecture and art. The “Social Urban Zone” is an attempt to enhance the public space with targeted, minimal architectural interventions. The unusual “Trinkbrunnen” (drinking fountain) by conceptual artists Frank and Patrik Riklin from Atelier für Sonderaufgaben is the first and central intervention of an overall system in which the given maxims of “more than art” are reflected in the “more than living” project and put to the test. In spring 2014, two further minimal architectural interventions were implemented. All three measures are conceptually linked and are the subject of a complete test setup.

Inter-Community School Zurich, Volketswil , 2010–2014, 1st prize

The Inter-Community School Zurich was founded in 1960 and offers international education in English for children and young people between the ages of three and eighteen. As an extension of the existing premises in Zumikon, a second school complex is to be built in Volketswil. According to the client’s requests, the design has to be as flexible as possible to allow for possible adaptations to future requirements. Our concept is oriented towards the human scale and creates a diverse and inspiring environment with different spatial sequences in six individual buildings. We pay attention to a balanced emphasis of indoor and outdoor areas: in addition to being a place of arrivals, the courtyards are also dedicated to games and sports. With their varied characters, they allow very different uses and combine the surrounding buildings and classrooms into a single unit. Teachers and students will be able to identify with both single buildings and individual places.

Esplanade Nord, Biel , 2013, 2nd prize

The urban planning dimension of this building project demands an extraordinary architectural response. For the appearance towards the esplanade, we are looking for a striking urban motif that is, in the sense of an initial spark, evolving into an unmistakable identity carrier of the new urban quarter. The curved façade consisting of two alternating arch segments (A-B-A-B) adds a rhythm to the entire length of the esplanade. The vertical fluting sets a counterpoint to the dominant horizontal expansion of the initial urban planning situation. At the same time, it allows a considerable building depth, so that the entire volume can be realised in the eastern perimeter as a block edge development without any backyard building “in the second row”. All apartments benefit from the generously laid out courtyard. For the internal organisation, the dynamic façade generates a variety of visual references towards the public urban space.

On the ground floor of House A, a part of the overall “More than Living” project, we implemented the tenant’s fit-out for the Züriwerk Foundation. The studio employs up to 28 people with cognitive and/or multiple impairments in five work rooms. It offers those who, because of their handicap, cannot work in a productive way the opportunity to pursue an activity appropriate to their abilities and to participate in the newly created part of the city. The distinctive supporting structure of the apartments above, which is visible on the ground floor, proved to be a suitable layout for the operational and assistance concept of Züriwerk Foundation. The arrangement of the studios and the various lounge and break rooms reflects the interplay of private areas and common rooms in the apartments. The work rooms are connected by sliding doors. Generous glazing promotes visual contact and allows the occupants of the house to participate in the employment service.

Stadtstück, Schlieren , 2014

Our resident is an urban nomad. He is in his early 20s to late 30s and always on the go: an internship in Dubai, a new love in London, a summer in New York. It’s about keeping as many options open as possible. “… GEORGE ?” is a temporary home, a base camp for excursions to new adventures, the place to return to and be at home within seconds. Individualists and bohemians with a greater experience of life join in. The entire volume will be accommodated in a single building, 9.80 m deep and 500 m long. The building structure is—like a writing—inscribed in the perimeter and generates a lively empty space as a common internal centre. On the edges, the undulating backward and forward movement creates urban niches and gives the complex a distinctive, unmistakable appearance on all sides. The building site is accompanied on both sides by high-speed road axes; the basic figure takes up the theme of dynamics and, in a kind of turbulence, creates an adequate termination to the somewhat uniform rows of buildings from the previous development projects in the direction of the city.

Living in the Ried, Köniz , 2013

On the one hand, the vision of the master plan defines clear interfaces between the residential area and the landscape, and on the other hand, a high degree of permeability is required. We interpret the residential development as a series of individual city villas that serve as connecting links through their loggias. In this way, the building areas are precisely framed on the outer edges, while at the same time, various visual references are created between inside and outside. The expanse of the surrounding landscape can already be felt at ground floor level, a quality that will have a direct impact on the use of this courtyard, which is more than just a circulation area providing access: it is a place of encounter and community. The staggering of the building volumes on the “soft” inside supports the villa character of the individual houses and creates intimate places, niches, and retreats for the garden apartments. The terraced layout ensures a pleasant scale, while at the same time the courtyard is occupied and actively used on several levels.

Hochweid Retirement Home, Kilchberg , 2013

Elderly people in very different life situations find a home in the old people’s centre; this is reflected in the urban development figure: old people’s home and old people’s housing estate are perceived as separate institutions, but nevertheless appear as an ensemble in architectural terms. In accordance with their different housing offers, the planned extensions are, as regards urban planning aspects, integrated into the development in a differentiated manner. The new residential complex complements the existing facilities of the retirement home to form a courtyard that is enclosed on three sides. With its large, slightly sloping roof, the new wing blends in with the topography, while the view of the landscape from the upper floors of the existing buildings remains unobstructed.

In the area providing communal rooms, selective extra high areas give the new building its own volumetric identity. With a limited building depth of around ten metres, the apartments stretch from façade to façade as a spatial continuum; in accordance with the unobstructed view across the neighbouring houses, the main residential side and thus the orientation of the loggias changes from east to west. Living, eating, and cooking stretch out between the longitudinal façades, the loggia of the living area is oriented towards the corner of the building. An “open” room, which connects to the living area with a wide sliding door, reinforces the spatial permeability along the façade; the expansive view is the decisive theme and staged in an impressive manner.

Waldmeisterweg, Zurich , 2013

The project is based on a cross-shaped figure that tapers slightly towards the ends so that increased clearances towards the neighbouring plots are avoided. The result is a longitudinal building structure that accompanies the course of the road and leaves the necessary open space for the garden side. The “central risalit” on the street side divides the building volume into three unequal façade sections. Despite the massive densification, familiar building lengths of the immediate vicinity are taken up. In favour of a stronger interlocking, the south wing projects a little further into the green space. The top floor is so recessed from the main volume that the new building appears to have three full storeys plus a raised ground floor—with a building height of 11.5 m a moderate transition to the predominantly two-storey neighbouring development. The standard floor accommodates six residential units sharing one circulation core, which are laid out as four 4-room apartments and two small apartments. In total, there is room for 18 apartments and two studios.

School Fischbek Falkenberg, Hamburg , 2013, 2nd prize

The grounds of the Fischbek-Falkenberg School (Fischbek location) impress with their green park with an extensive bush and tree population. The architectural concept strengthens the park as the heart of the school landscape. New and old buildings naturally blend in to form an ensemble that defines the site boundaries and simultaneously creates an open and permeable interior space. The given heterogeneity is reduced by the uniform architectural vocabulary of the new buildings as a whole. As two-storey pavilions, the buildings subordinate themselves to the park with its existing trees. At the same time, their limited height allows them to harmoniously merge with the village-like environment. The cubature of the forum also integrate well into its surroundings in terms of expanse and height, as its narrow side opens up to the urban space. This results in a new, explicit presence: A spacious square is created, which clearly defines the entrance situation as an offer for the district to serve as a neighbourhood square, thus integrating the school more strongly into its social environment.

Seewies, Güttingen , 2013, 2nd prize

The building volume is divided into seven compact detached houses, so that all buildings can benefit from a view of Lake Constance. Two slightly different types of buildings, freely positioned on the site, ensure a relaxed variety despite the basic serial idea. Private gardens enclose the sculptured houses, each providing 8 - 10 apartments, like cushions. In between, a system of paths, squares, and alleys promotes the communal life in the quarter. The apartments on the first floor also have a direct connection to the garden via a “garden room” situated in the corners of the three-wing building types. It can be used either as an extended living space or as an autonomous unit in the sense of a “Stöckli”: as a guest suite, for the own start-up office or sewing studio, for the grandmother or a teenager. The volumetric recesses on the upper floors create generous terraces for the attic apartments—with magnificent views of the landscape around Lake Constance.

Bildungsmeile, Zurich , 2013–2017

Zurich University of the Arts (ZHdK) is moving to the newly designed Toni Areal in the western part of the city—the previously used areas between the main railway station and Limmatplatz will be available for new uses. The relocation also offers the opportunity to optimise the vocational schools located in this area today in terms of their operation and floor areas.

Wohnen am Hübelweg, Niederlenz , 2013–2014, 1st prize

“The project seeks a balance between village and landscape. The project authors therefore make the coexistence of density and expanse the overriding theme. A rather urban quality is consciously developed, which relates to the density of the core zone. […] In its architecture, the project takes up familiar images of village buildings and tries to integrate the distinctive building volumes in the rural context. The cultivated landscape that is structured with walls and terraces forms a concreted base for the new buildings. Above it, the buildings with a traditional punctuated façade are plastered. The modest yet characteristic architecture has an appropriate and identity-building effect.” (Excerpt from the jury statement)

Residential and Nursing Home, Frienisberg , 2013

The design is based on two different implementations of the same typological idea. In the “East” quarter, the main building forms a new, distinct address on Bernstrasse; on the west side, three “villas” are grouped around a village-like square, slightly elevated above the lake. The composition of the four elements monastery, main building, villa cluster, and barn defines the new village centre around Frienisberg’s central open space. Together with the historic buildings, the replacement buildings form an ensemble that continues the evolved village structure without competing with the monastery. The relocation of the centre also means an opening of the previously introverted institution to the outside world.

Eisweiher Areal, Oberwil , 2013

A comprehensive overall urban development concept for the Eisweiher site is to show structuring and design measures that contribute to the creation of an attractive district and high-quality living environment. The result is to represent an architectural density appropriate to the task, the place and the environment, a high-quality and functional access and circulation area as well as attractive outdoor spaces. This raises in particular the question of the architectural and outdoor character of the Eisweiher Quarter as a new component in the core area of Oberwil. (Excerpt from the competition brief)

Schütze Areal, Zurich , 2013

The Schütze Areal in District 5 is located close to the Escher-Wyss Square and is, despite its size, only noticed by a few. Travellers stay in summer, but at the same time the “urban wasteland” is an outdoor space for locals. In the future, Schütze Areal is to be a central meeting point in the district, but for this to happen, the site needs to be restructured and enhanced with attractive offers. With the concentration of the building volume at the eastern site boundary, a park area of maximum size is created, which joins the sequence of recreational areas typical of the area—such as Josefswiese, Turbinenplatz or the (…) Pfingstweidpark. At the same time, a heterogeneous courtyard with parking spaces, delivery zone, and work area will be laid out in the closed off block perimeter development.

Hotel Park and Seeallee, Heiden , 2012

The building site for the new hotel in Heiden is a sensitive place in the townscape. It marks the beginning and the end of the traditional spa promenade, which basically justifies a prestigious building for public use. Our design is derived from the silhouette of Heiden; the perspective staggering of simple cubic building volumes is incorporated into the project. By dividing the hotel into three individual units, its volume corresponds to its surroundings; familiar façade proportions of the typical classical Biedermeier houses are reinterpreted. The result is a modern building that nevertheless tells the story of the location. It is a distinctive building with a quiet character, which is able to integrate into the overall picture quite naturally and unpretentiously due to its peculiarities.

Letzigraben, Zurich , 2012, 3rd prize

The re-densification of districts offers the opportunity to make the city more tangible as a designed spatial continuum. The spatial dialogue of urban fragments turns the city and the district as a whole into an area of identification. The two sides of the perimeter are characterised by very different urban spaces, each with its own unique qualities. With the concentration of the building volume along the construction line at Letzigraben, the urban character of the streetscape is strengthened and Heiligfeld Park as the green centre of the district is extended up to the plot. The concave spreading of the volumes to the park side reacts to Steiner’s differentiated development and intensifies the orientation towards the park. In the dynamic context of open and enclosed urban spaces, the project seeks not only a balance between urbanity and greenery, but also between classification and independent identity.

Boarding School, Glarus , 2012

Until 2001, the Legler site in Diesbach was an active location for yarn and cloth production. The buildings date from 1856 (weaving mill), 1870 (spinning mill), and 1919 (new spinning mill). A special feature is the factory’s own hydroelectric power station, which has ensured energy autonomy right from the start and is still in operation today. The current owner intends to convert the site for a second use. For this purpose, the building stock is analysed regarding its suitability as a boarding school. The idyllically secluded location and the proximity to various recreational areas (Braunwald ski area, Lake Walen), and good connections to the greater Zurich area (1h without changing trains since 2014) are important advantages of the location. Three typological floor plan layouts are verified: A) conventional classrooms along a central corridor, which can be combined in pairs in the sense of “team teaching”, B) a group room concept as is currently popular in public schools, and C) an innovative teaching concept with open, informal learning zones and so-called “break-out areas”. Depending on the educational concept, about 100 - 250 students could be taught at the boarding school on the Legler site.

WAZ Media Office, Essen , 2012

The current building structures of the Essen-based media group consist of a series of building complexes of various construction methods and quality. An office structure that has been used for many decades and leaves little room for communication, openness, flexibility, and spatial changes is no longer in keeping with the times and the creative work of the company’s employee. WAZ Media Group has therefore decided to relocate its current location at Friedrichstrasse in Essen. […] With the help of an architectural competition, WAZ Media Group is looking for new building concepts that […] enable an individual working environment with most economical operation. (Excerpt from the competition brief)

House Shmerling, Gossau , 2010

A single-family home in the style of the 1970s is renovated, extended, and divided into two units. In the “east wing”, a living hall is built at garden level, while the building’s original concrete structure remains visible. On the upper floor, French windows open up the south-facing rooms towards a sun terrace. The interiors in the “west wing” benefit from the extra high living space that opens up onto two private terraces after the conversion. The existing gallery will be reactivated and converted into a library with a wall of books stretching along its entire length. The building is thus transformed into a cubic-modern house without completely concealing the distinctive characteristics of its original structure.

Kronenwiese, Zurich , 2010, 9th prize

The three sides of the perimeter are characterised by very different urban hierarchies. The project derives its specific shape in dialogue with the site conditions. The strong building completes the streetscape, follows the topography and forms a new, self-confident face towards the intersection with Nordstrasse. The balance between independence and classification, between a new identity and the continuity of the city is sought. At the rear, there is a large open space, protected from the noise of Kornhausstrasse and with an unobstructed view towards Limmat and Uetliberg. The duality of these two different sides becomes the generator for an independent apartment typology with flowing room geometries and a “soft” loggia layer.

High-rise Buildings, Baden , 2009, 4th prize, special prize sustainability

ABB’s industrial area, which was formerly hermetically sealed off, is increasingly becoming the service area of the City of Baden. According to an existing area study, two high-rise buildings with space for about 2,600 jobs are to be created on the last available sites next to the SBB tracks. Ideas for the layout of the Brown Boveri Square on the southern part of the site are also requested. We design a service machine with an elegant dress. A superordinate scale is introduced through a fine relief of the façade envelope to counteract the repetition of storeys and the 1.35m grid. “Airboxes” are integrated into the façade on each floor to process and provide supply air locally. In this way, we avoid space-consuming central plant rooms and raiser zones. On the outside, the boxes harmoniously integrate into the façade appearance and become an ornamental sequin motif. Energy is generated by offset photovoltaic elements on the slightly sloping roof surfaces.

Spinning Mill and Twisting Mill, Windisch , 2010

The former spinning mill building in Windisch is about 70m long and 27m deep. With the most sparing interventions possible, we transform the former production site into housing space, which benefits from the existing qualities: a field of filigree steel columns, framed by solid brick façades. With cabinet elements and few partitions, the wide field is divided and given a homely feel. The fixtures thin out towards the physical building envelope to make room for an enfilade. The staircases each provide access to 4-6 apartments as well as interior workrooms and storerooms. The existing structure is exposed and contributes to the formation of an identity for these special apartments.

Storytelling, Basel , 2010

In a professional context, the development of an architectural idea has become more and more a weighing of different and sometimes contradictory constraints. The optimum solution is sought between standards, laws, and efficiency requirements. This rationally comprehensible optimisation process leads to an increasing standardisation of the built reality. This development of uniformity is opposed by a very human need: the desire for individualisation because behind every standardisation is the threat of exchangeability, of one’s own disappearance. In architecture, too, art begins for us where we depart from rules and well-known systems of ordering. As architects, we have the responsibility not only to take an engineering science perspective but also to search for immaterial needs that are difficult to express in figures. We are looking for answers that give identity to places and buildings, houses should once again tell stories.

Hohlweg, Rapperswil , 2010

The floor plans of the apartments are organised around a central circulation core with a naturally lit stairwell. From here, four or five apartments per floor are accessed. Despite the great depth of the building, almost all apartments are oriented towards two sides and thus benefit from the varied views to the depth of the outdoor area. The heart of the apartment is a spacious hall. Here, guests are greeted and shopping is put down, here is the telephone or a comfortable armchair to put on one’s shoes. The hall is more than just a distribution room; it is the centre around which all rooms are grouped. This means, for example, that a 3-room apartment has a fourth room instead of a cramped corridor. Versatile spatial and route relationships and an internal circuit combine functionality with a feeling of generosity.

Dosteba, Bachenbülach , 2007–2014

The production hall, where semi-finished products for thermal insulation systems are manufactured, is extended. The rapidly growing company takes the opportunity to restructure the cluster-like building and to reorganise the complex flows of materials and staff. The new office wing also serves as a roof over the delivery zone and internally connects the gallery floor of the production area with the offices and staff rooms.

Findling, Baden , 2011–2014

For an apartment building in Baden, we designed a cubic solitaire on a narrow, triangular plot on a slope, which defies the architectural context and anchors itself in the slope. There is no staircase; instead, three apartments are stacked in such a way that they each have their own entrance. Each apartment is based on a cruciform basic structure, which is, however, individually interpreted: On the ground floor, a family apartment with a large kitchen, terrace and garden is laid out. Above is a loft apartment with a magnificent view to the Limmat Valley, and the attic apartment is based on a room-to-room principle with an internal private patio.

Schwamending Triangle, Zurich , 2011

The modernisation of a cooperative “Gartenstadt” in Zurich-Schwamendingen is confronted with completely different requirement in view of the globalisation of the economy and individualisation of lifestyles than was the case at the beginning of the Gartenstadt more than 100 years ago. The idea of a “better” city for the working class on a greenfield site was reduced to a land reform just a few decades later. It is no longer a social utopian social model that shapes the housing concepts, but the provision of affordable living space with qualities such as light, air, sun, and lots of green for everyone. Unlike today, density was not seen as a quality but as a necessary evil to create affordable housing. In these respects, the garden cities are in no way different from the satellite cities of the ideological adversaries of programmatic modernity. We propose an architectural and open spatial structure that is based on a few fixed parameters but still leaves sufficient scope to keep strategic options open regarding “uncertain” issues. Essentially, the following parameters determine the urban development proposal:

  1. Urban development on a neighbourhood scale. Adequate staggering of building heights and density.
  2. Neighbourhood clusters as identity-forming, manageable social units.
  3. Participation and sustainable development. Planned change management.

Industriestrasse, Luzern , 2011

A heterogeneous and fragile development with a rectangular pattern is the starting point for the development focus on Industriestrasse. We see great qualities in this evolved structure and thus potential for future construction projects: the maximum possible permeability has to be maintained for the dense positioning of living and working next to and on top of one another. This is the only way for future users and residents to network with the structures of surrounding quarters. The concept is therefore principally based on a harmonious balance of figure and site. In the dense plinth zone, we create empty spaces, paths, and squares. Above it rises an “airy” living environment. The six towers take up the familiar density structure of the surrounding development. Two basic types are designed with three respectively four apartments sharing one circulation core, which allow the layout of apartments oriented to two or even three sides and a variety of visual connections.

Balberstrasse, Zurich , 2011

The new buildings are to blend into the peaceful and tranquil atmosphere of the existing residential development on Balberstrasse. The building mass consists of three low and four taller volumes, which adapt to the basic urban planning pattern and try to optimally deal with the hillside location. Their construction method is designed to include a high proportion of wood in order to meet the requirements of the “2000-watt society” in an ecologically and energetically sustainable manner. The distinctive roof shape and the generous loggias tie the ensemble together. A dense network of paths connects the individual houses at various levels of privacy and leads past the cooperative rooms, such as the common room or the studios. The loggias serve as a switching zone between public and private spaces and become a place to meet.

Beyond rational, Zurich , 2010

“Showing objects, projects, and ideas from young architects now practicing in Zurich, the exhibition hopes to highlight not only the emerging voices of design but also the thoughts and trajectories that have resulted from contemporary tools and techniques. Liberated from the prosaic constraints of typical construction projects, and the functionalism that often follows technology, the exhibited works chart relationships between technology and design, whether high- or low-tech, whether material or immaterial, to speculate beyond just the rational. Duplex Architekten present material and spatial studies for current architectural projects, the results of a sensibility that embeds architecture within a culture of making.” (Jeannette Kuo, Curator)

East Side, Windisch , 2010

On the site east of the old spinning mill in Windisch, the design of Atelier WW proposes four linear building plots for new residential buildings. We dare a free interpretation within the specifications of the master plan and form a separate inner centre, a courtyard for the quarter with private gardens, which spatially incorporates the spinning mill building. The building lines are divided into seven clearly defined individual volumes to avoid long alleys. Their strictly serial structure promises an economic implementation. Special attention is directed at the attic floor: four 4 ½-room maisonettes are interlocked in such a way that each apartment is oriented to three sides. Generous terraces connect the apartments with the expanse of the former industrial area and the adjacent river landscape.

Gleis Nord, Lenzburg , 2010

The Gleis Nord project creates a new heterogeneous living environment in Lenzburg, embedded in an attractive green belt. The design responds to the current urban planning situation—on the one hand, the marked outline of the quarter and, on the other hand, the large-scale development—and defines the area to the north and west with a clear, recognisable outer edge. Squares and retreats are laid out, the green area interweaves with the urban space and provides a high quality of living. The residential buildings feature an individual design and different typologies: The “Genossenschaftshaus”, for example, has one circulation core for three to five apartments per floor, and the living rooms extend into the park via loggias. The senior citizens’ home, on the other hand, has arcades; the arrangement and size of the rooms give the residents the freedom to expose themselves more or less to the adjoining communication area. The family apartments are extended by rentable studios, small apartments, and cooperative uses. The public parking area can be used equally by all residents. Furthermore, common rooms, public-oriented uses, restaurants, kindergartens, and launderettes liven up the ground floor zones.

Limmatfeld Town House, Dietikon , 2010

On the basis of Hans Kollhoff’s master plan, apartments for around 3,000 people are being built on the former premises of the machine manufacturer “Rapid”. For one of eleven building plots, the Zypressenhof, we designed a town house as part of the 18m deep block edge development. We focus on a perforated façade with a classic three-part structure. Smooth, shiny ceramic surfaces alternate with a coarse-grained plaster finish. Folding sliding shutters made of ornamentally lasered metal sheets close the openings of the loggias like a thin skin, thus creating an exterior room with great intimacy for the apartments. The loggias can be fully opened up towards the kitchen and bring the afternoon sun deep into the building via a dazzlingly reflective longitudinal wall. The floor plan combines conventional elements with generously proportioned, open-plan living areas.

Multigenerational House, Winterthur , 2009

The given urban development situation shows exciting contrasts: The hybrid cluster regulations define strong urban planning references, while the intended residential use demands independence due to its exemplary character.

The project responds to this original situation by having two buildings form a common courtyard that is comparable in size and shape to Steinberggasse. Without causing a severe break, the public outdoor space is juxtaposed with a semi-public interior. The iconographic shed roofs refer to the industrial past of the site, connect the two buildings, and create a strong common identity.

Up to 35, Athens , 2009

In favour of a generous common area that can be used flexibly, the actual sleeping cells are reduced to basic elements: a bed, a closet, a window, and a door. Retreat to a private area is also ensured on a limited floor area—for reading, talking, making phone calls, and daydreaming. The heart of the house is a six-metre high reading room in the basement, where each student occupies a place. The generous glazing on the ground floor allows concentrated work in daylight and simultaneously offers a view of the street. A free-standing staircase leads to the semi-private upper floors. A loggia in the courtyard expands the front zone to the rooms and creates its own internal world.

School Complex Looren, Maur , 2008, 3rd prize

A large roof lies over a kind of retaining wall like a shell. The functional rooms are grouped behind this wall. The foyer, which opens up onto the forecourt, occupies the space between hall and rear. The roof itself is designed as a folding support structure, which is visible on the inside. In the model, we have checked the rich play of light of the finely folded roof geometry.

Felsenstieg, Schaffhausen , 2008, 2nd prize

Instead of filling the gaps along Lochstrasse like a dentist, the building site is “overprinted” with a group of four congruent building volumes. Familiar building lengths of the existing 1920s Karl Moser houses are taken as a reference, without denying their own time. The free geometry of the volumes enables economic access and circulation via a generous central staircase. The spaces in-between spread out an open area that varies between wide zones with views and intimate, densely planted areas.

House Emil, Bachenbülach , 2007–2010

A single-family house on a slope is extended by a residential unit through maximum lengthwise expansion. Both inside and outside, new and old remain distinguishable, but the interface is blurred by spatial overlaps. The focal point of the new apartment is the extra high living space, which brings the existing gable facade into the interior. In the tradition of Loos, a series of rooms with different characters are integrated into the simple, iconographic building volumetry. Two connecting elements hold old and new together like a bracket: On the north side, the roof opens for a continuous window strip; in the south, a loggia extends along the entire length of the building. It interferes with the semantics of the existing building and reinterprets what already exists. The annexe is constructed as a self-supporting timber structure. The walls and ceilings are prefabricated and placed into the in-situ concrete shell. The concrete shell gives the building its distinctive expression. The concrete has a stony appearance due to the admixture of crushed Jura gravel and white cement. Without any colour pigmentation, a light, warm and natural shade is thus achieved. In addition to the smooth surfaces showing the formwork pattern, some parts are sandblasted. The subtle interplay of different surface textures makes familiar motifs appear or disappear, depending on the light.
