Exemplary and forward-looking neighbourhood

The Metzgergrün quarter is set to change significantly and develop into a contemporary neighbourhood without losing its original character. A modern residential neighbourhood with around 500 new flats and generous green spaces will replace the 27 ageing terraced buildings from the 1950s. Quiet inner courtyards, a lively public centre, high-quality and differentiated open spaces and a new network of paths create an exemplary and forward-looking neighbourhood.

Our design organises the flats into six blocks that form manageable neighbourhoods. Each block combines three- to four-storey terraced buildings and point houses around a green inner courtyard. Along the road and railway line, an L-shaped, elongated block shields the development.

Public living room for curious people

The library of the city of Dornbirn is a place of exchange, encounters and intergenerational learning. As a kind of public living room, it is intended to promote reading and language skills, the exploration of digital search methods and new forms of communication. Curious people with similar goals meet here and can immerse themselves in the material or engage in dialogue with one another.

Set in a park, the oval pavilion with a façade of 8,000 stylised ceramic books is an independent form and stands in stark contrast to the rectangular buildings in the surrounding area. The starting point for the design idea was a beaten path that ran diagonally across the meadow. We placed the library building on this path so that it runs lengthways through the two-storey atrium.

Compact quadrangle with large patio

Demolish or renovate? This question often arises when it comes to the further development of school buildings from the 1970s. The Lycée Evariste Galois in the Paris metropolitan region no longer meets current requirements and is bursting at the seams due to strong demographic development.

With a holistic approach to the environment in mind, we decided to restructure and extend the building. Based on the qualities of the existing building, the individual parts will be reorganised and combined to form a communicative whole.

The new, green schoolyard forms the heart of the ensemble and connects the various functions. It is shaded by a curved canopy on slender supports, through whose large, circular openings daylight floods in and trees grow. We have extended the U-shaped school building into a compact quadrangle with a large patio.

Striking alternative to the "Uniform Alpine style"

The Gourmet Hotel "Rote Wand" goes back to an inn next to the church, which has developed into an impressive hotel complex with six houses. We have been overseeing the regular modernisation and expansion phases since 2007. The long-term development concept is based on high-quality architecture and local craftsmanship.

Connected by a common base and the Red Corridor, the six buildings form a resort that is surprising in many respects. The Dependance and the Appartement house are also connected underground to the main building. The Dependance replaces a demolished guesthouse, and we also took this opportunity to make a correction. The cross-gabled buildings from the 1970s facing the valley above the church were replaced by longitudinal gabled buildings facing the slope on the eaves side. The gourmet restaurant "Altes Schualhus“ was added in 2015 as the last building block for the time being.

Zug, once a small hamlet with a church, schoolhouse and a few farmhouses, lies somewhat off the beaten track. In contrast to most other high Alpine tourist destinations, the village has managed to retain its rural atmosphere. This is mainly because, even during the decades of development from a farming village to a holiday resort, the buildings of the old set the standard for the new. Thanks to its dominance in the village, the "Rote Wand" hotel complex makes a significant contribution to the typical townscape and formulates a striking alternative to the widespread "Uniform Alpine style".

Growing office ring with great appeal

The legero united campus in the south of Graz consists of two round buildings of different sizes. The larger office ring can be extended by a further floor at any time. This fulfils the client's wish for a company headquarters that "grows with the company" and can be expanded in stages, without creating a temporary structure, a torso. The smaller cylinder houses the shoe outlet.

Generous glazing, the façade made of bronze-coloured, anodised aluminium that shimmers in the sunlight and the lushly planted inner courtyard blur the boundaries between inside and outside. The result is a campus as a place with its own identity and great charisma, a dynamic yet harmonious composition, at all times and in all phases of construction.

Living and working in the south of Favoriten

The "An der Kuhtrift" site, previously used as a car park, is located directly next to the Therme Wien spa and the Oberlaa spa gardens. An innovative, mixed-use building complex is now being built here with flats and offices as well as shops and a park & ride facility at the base. The somewhat lost-looking urban space is now structured by two solitary buildings and conveys an urban flair. The rounded triangle of the office tower forms the prelude. At the other end, the trapezoidal head building with commercial housing and restaurants and the entrance to the supermarket characterises the square in front of it.

Between these two towers is a plinth with commercial and office space and an intensively landscaped roof garden. Above this, three residential buildings of different heights and sizes "float" on a mezzanine floor. On the lower building in the centre, the residents have access to a shared roof garden. Apart from the concreted plinth, all components are designed as a timber hybrid structure. The unused roofs are greened and extensively covered with PV elements.

10 institutions under one roof

Located in one of Innsbruck's most prominent squares, the House of Music serves as a centre for open cultural exchange across all age groups and genres. The unifying theme is music. The complex spatial programme accommodates several music institutions, concert halls, numerous ancillary rooms, administration, catering, a national music library and outdoor terraces with views of Innsbruck and the Alps. The new building provides the city with a sustainable centre for music, theatre and all kinds of cultural events and also positions Innsbruck internationally as a "city of music".

The austere cube is vividly structured by atriums and incised loggias, terraces and recesses and blends in sensitively and yet excitingly with its historical surroundings. The surrounding historic buildings and three protected trees with the Leopold Fountain on the forecourt are reflected in the glass surfaces.

A contemporary interpretation of local architecture

With the "Seegut am Tegernsee", a new neighbourhood is being created directly on the lakeside promenade. It is divided into three areas: the hotel in the north, the residential development in the south and a public area with an inn and cultural barn in the centre. The ensemble is embedded in an extensive and varied green space concept. The architecture and arrangement of the 25 individual building blocks pick up on the local architectural style, transform it in a contemporary way and integrate the Seegut harmoniously into the surrounding landscape.

Most of the buildings are designed as sustainable timber constructions. The heating and cooling requirements are covered by thermal lake water utilisation. The project is being planned and realised by three teams of architects - Maier Neuberger, Innauer Matt and Dietrich Untertrifaller. Enea Landscape Architecture is responsible for the design of the connecting bracket of the outdoor facilities.

Aiming high with wood

A mosaic is made up of many individual pieces that fit together harmoniously. Colourful, modular, lively and connecting - this is also what the Moosaik urban quarter at the entrance to Starnberg is to become. At the centre of this district, we are building a timber office tower. Called Moo 6, it complements the surrounding ensemble of buildings with its height and presence and forms the unmissable centrepiece of the quarter.

The restaurant area on the ground floor with its large terrace creates a link between inside and outside. The flexibly divisible office units on the upper floors attract a wide variety of users and thus ensure diversity and vitality.

Uncompromising cluster school

The Unterdorf primary school in the municipality of Höchst in Vorarlberg is a radical and uncompromising realisation of the modern "cluster school". Cluster school means teaching in small groups, flexibly usable rooms and varied open spaces, preferably with an outdoor connection. We have housed four identical clusters for 200 pupils in a simple, elongated, ground-floor wooden building on the east side.

At the centre of each cluster is the common room, topped by a high truncated pyramid with daylight streaming through the skylight. Gardens and outdoor classes with direct access from each cluster blur the boundaries between inside and outside and integrate nature into the learning environment. Special classes and the administrative offices are located opposite on the west side, connected to the lowered gymnasium by a spacious assembly hall. Parts of the outdoor areas are available to the local population as a freely accessible play and leisure area.

With 940 points, the school in Unterdorf received one of the highest scores ever for a new building in the Municipal Building Pass of the state of Vorarlberg.

A congenial addition

The new, multifunctional Hall F for 2,000 visitors is a congenial addition to Roland Rainer's imposing Wiener Stadthalle. Built in a key urban location, the hall sends a clear signal to the outside world with its cantilevered body. Below the cantilever is the modern foyer, which provides access to the various halls (banqueting hall, rehearsal stage, large hall). The outer shell consists of aluminium panels that extend into the interior of the building.

The crystalline, polygonal building fills the empty space between Hütteldorfer Strasse and the Stadthalle, whose struts are reflected in the glass north façade of the new building. This precise positioning optimises the previously rather unsatisfactory urban situation and defines the adjacent square and street space.

We won the international competition held in 2002 with a project that was convincing in terms of form, function and urban planning.

Flexible working in a wooden office

In the Swiss municipality of Baar, we are constructing the innovative NEXUS office building. The sustainable timber hybrid conserves resources through renewable, reusable materials and a consistent cradle-to-cradle concept with minimal use of reinforced concrete. Recycled concrete is used wherever possible and we prefer to use wood from the region for the timber construction. A sophisticated low-tech system takes care of heating, cooling and ventilation and, together with efficient insulation, reduces consumption during operation and therefore costs over the entire life cycle.

The well thought-out space concept creates an attractive, modern working environment, promotes dialogue and networking and offers maximum flexibility. This allows the building to adapt to its tenants and future developments. The four differently dimensioned wings of the cross-shaped building are freely accessible via four axes. The clear structure with a central access core and circumferential walkway with attractive views allows for easy routing. Plenty of daylight and light-coloured wood as well as large areas of glazing with views out and through create a pleasant working environment. The park around the building and the roof terrace with views as far as the lake invite people to linger.

Living on the car park

The Dock-1 building site on the Rhine Canal (Petit Rhin) marks the start of the redevelopment of the "Citadelle" harbour district. The mixed-use project with 83 flats on a multi-storey car park interweaves various functions and creates a communicative place around mobility-related spaces.

Visible from afar, from the Parc de la Citadelle to the Vauban Bridge, the building blends into the urban context and characterises its identity as an "eco-district". Situated between the two harbour basins, Dock-1 is an atmospheric place with a strong identity and a direct connection to the city and water – ideal conditions for a high quality of living and a new form of urbanity.

The powerful large form makes a strong gesture to both sides. A five-storey multi-storey car park is stretched between two cross-shaped, elegantly balanced residential towers, above which are further flats with shared, spacious terraces on both long sides. The centre of the project is a high hall on the ground floor, designed as a pedestrian gallery, which can be used for a variety of purposes.

Kuku 23 – Living in the art & culture quarter

A new residential district was created along Gastgebgasse in Liesing, in the immediate vicinity of the Sargfabrik cultural centre and the Atzgersdorf educational campus. Four blocks of flats and the studio building offer space for 430 subsidised flats, workshops, studios and a dance and music school.

We developed the concept for the Kuku 23 residential quarter with the aim of providing low-threshold cultural activities, especially for children and young people. After all, Vienna's southernmost district needs more art and culture.

The buildings are divided into individual "houses", visually separated by naturally lit joints. This allows for varied roofscapes, better lighting conditions and a more human scale. The studio house mediates between the coffin factory and the school campus and, with its two-storey passageway, leads over to the open-plan residential development. The special feature of the studio building is the open supporting structure, which is broken down into individual column slabs and enables a variety of room programmes.

Habitat with typological and social diversity

Our concept for Kleineschholz integrates a wide variety of living and building types, with a focus on affordable housing. The typological range of the building structure and the mix of rental apartments, condominiums and building groups ensures the desirable social diversity. Families and singles, children, young and old, locals and newcomers live here. Craftsmen, self-employed professionals and service providers work here. Together, they form a stable, self-regulating social structure made up of different responsibilities, life cycles and local connections.

The western edge of the Stühlinger district in Freiburg is mainly characterised by large administrative buildings, which are well frequented during the day but leave the streets empty in the evenings and at weekends. The urban redevelopment will create dense residential neighbourhoods that will allow for diverse, lively use, enliven the district and ensure safety.

An identity-forming ensemble of old and new

The Rudolf Steiner School in the Maurer Schlössl, founded in 1964, is Austria's oldest Waldorf school. The lower school and after-school care centre were housed in a small old building opposite, which could no longer meet the requirements of a modern school: poor building fabric, too few and too small classrooms, no gymnasium.

The new building blends harmoniously with the existing historical building - we have avoided any sharp breaks between old and new. The auditorium, the dining hall with garden orientation, the sunlit, sunken gymnasium, the after-school care centre, the kindergarten and the roof terrace form the main elements of the clearly structured room programme.

The majority of the remodelling and extension work was concentrated on the southern side facing away from the street. On the street side, the character of the old building was retained and visually enhanced. The small extensions at the rear were demolished and replaced with spacious, naturally lit foyers and access areas. The new building with gymnasium and classrooms adjoins the rear garden in an L-shape. Its large, dark roof extends onto the existing building and is therefore also visible from the street.

Farmhouse outside, museum inside

On the hillside to the west of the village centre, there are two small museums in a historic, carefully maintained farm house from the 16th century. The old residential part serves as a local history museum. The new Angelika Kauffmann Museum fills the former agricultural wing and is accessed via the barn and threshing floor. A wide sliding partition can be pushed aside and the museum is open. When it is closed, the modern wood and glass construction is no longer visible.

The exhibition hall was inserted into the barn as a flat-roofed "building within a building". Space-forming elements define the exhibition hall, but also evoke the former farm building – a sophisticated architectural dialogue.

With their meticulous work, the craftsmen – rooted in local tradition yet are familiar with the latest technology – put the finishing touches to the project. All the parts fit together and blend into the long building history of the house.

From the barracks to the creative quarter

On the site of the former Luitpold barracks, the Creative Quarter Munich is being established, a colourful, mixed-use district characterised by social and ecological sustainability. Living and working will be combined with art, culture and knowledge, with a focus on the community. The neighbourhood is divided into four different areas, which are interconnected but can be developed independently of each other.

We have designed two buildings with around 350 flats for the "Creative Platform North" site. Along the newly emerging main axis, the central Romy-Schneider-Platz, which connects the Munich University of Applied Sciences in the south-east and the urban cultural area in the north-west, we proposed to programme the ground floors with public uses. Under the inviting, large arches and arcades in the base area, cafés and small shops are to enliven the neighbourhood in future.

Wooden school, sports hall and library

The new school and the multi-purpose hall were built in two phases ten years apart. The spatial concept of the L-shaped building comprises three main functions: School, sports hall and library. Completed in 2003, the school was built in timber construction in a record time of 18 months and was the first school building in Austria to fulfil the strict passive house guidelines.

Ten years later, the new multi-purpose hall replaces the gymnasium, which was in dire need of renovation. Precise planning, a compact organisation of the programme and a high degree of prefabrication allowed for a short construction time and optimised costs without making compromises on design and quality.

With this pilot project, we have proven that resource- efficient construction is very well possible in harmony with high architectural standards. The school building has received several architecture and energy-saving awards, including the State Prize for Architecture and Sustainability.

"Light, freshness, generosity"

To this day, the slogan of the 1972 Munich Olympic Games still applies to the TUM School of Medicine and Health in Munich's listed Olympic Park. The two-storey timber building, 185 metres long and 153 metres wide, forms the new, striking address for the Faculties of Medicine and Sport and Health Sciences.

The 19 metre cantilevered canopy is a special timber construction made of prefabricated box girder elements that was assembled without the need for complex auxiliary scaffolding. It was important to us to fulfil the diverse requirements of the users in the best possible way. All functions - 14 sports halls, 12 lecture theatres, 15 diagnostics rooms, 5 workshops, 300 offices, cafeteria and library - are combined under one roof in the bright, lightweight timber construction.

The two streets – "Rue intérieure" in the building and "Rue extérieure" for the outdoor facilities –are the defining element, they serve as ameeting place, an access zone and a place of communication.

Focus on social sustainability

On the "In der Wiesen Süd" site in Liesing, we worked with ARTEC to build an attractive residential complex with 310 flats, five studios and a residential community for young people. The main challenge was to develop a cohesive neighbourhood that promotes joint activities between the neighbours across building sites and thus enlivens the area.

We designed the northern area with three buildings that form a central, quiet square for the residents. The bends in the two solitary buildings open up the area to the south and promote permeability.

A circumferential band of loggias and the full-surface glazing bring light and openness into the flats and offer expansive views of the park and the city. A particular highlight is the light-flooded atrium, which is remarkably spacious for a subsidised residential building. A variety of visual connections ensure attractive and communicative access to the individual floors.

New splendour, also behind the scenes

Built in 1889 in the neo-Renaissance style as a bourgeois counterpart to the Burgtheater, the theatre offers 850 seats and the famous Red Salon. The aim of the urgently needed renovation and remodelling work was to offer the audience contemporary comfort, establish modern safety standards and improve efficiency. We therefore extended the stage area, reorganised the audience area and ensured accessibility and safety.  

The façade lighting also makes the new old splendour of the building visible from the outside. To improve the thermal quality, the richly structured plaster façade of the theatre was cleaned and renovated in agreement with the Federal Monuments Office. The entire listed building and its original character were retained.

Wood, exposed concrete, fresh red and lots of glass

The all-day school north of the 3,000-strong community of Broons in Brittany is one of the most important educational institutions in the region. 570 children aged between 11 and 14 from 29 municipalities attend the school. The three-storey school wing stretches across the entire width of the site and is bordered to the west by the single-storey canteen, whose flat green roof merges gently into the lawned landscape.

Together with the outer wall, the school wing and canteen enclose the schoolyard. The entrance, protected from the weather, is located on the narrow street side. The two-storey timber construction of the classroom wing rests on a concrete base, which houses the event rooms, library and administration. A promenade running parallel to the street forms a pleasant and safe footpath from the town centre to the school outside.

Between transparency and unity

The new sports hall on Alter Postweg (the old postal route) in Vaihingen an der Enz was built as a compact, functional and very economical hall construction using timber elements. Only the parts in contact with the ground are made of reinforced concrete. The building is divided into a three-court sports hall with spectator area, a three-storey functional area and a multi-purpose wing with foyer.

All functional areas are united under one roof. We utilised the sloping terrain and built a large part of the hall into the slope. This meant that the functions could be spread over several levels, while the hall remained suitably low on the street level.

The flat façade made of perforated and black-brown anodised aluminium meander sheet runs across the entire building and protects the areas behind it from view and sunlight. The interplay with the large window areas creates an exciting contrast between transparency and openness, which also supports the functionality of the building.

Bright.Robust.Innovative.Open

The innovative "Neues Landgut" district will be built near Vienna's main railway station in Favoriten by 2026/27. The 9-hectare site will be home to 1,500 flats and an educational campus, surrounded by attractive green spaces and recreational areas.

Under the title B.R.I.O., we developed together with PLOV Architekten, a socially, ecologically and economically sustainable project with 176 subsidised flats for our building site. The differentiated, socially balanced housing mix comprises 88 smart flats, family flats and floor plans suitable for shared flats. One focus is on the special needs of single parents.

B.R.I.O. is a robust timber hybrid element construction. The optimised support grid enables a high degree of prefabrication and economical use of materials thanks to the low ceiling thickness. This construction method and the use of timber and recycled concrete save around 20 per cent CO² compared to a conventional reinforced concrete building.

Clay, wood, bamboo, basalt

Building a school in Mayotte means dealing with many issues on several levels in a completely different way than here in Europe - in an educational, but also in a socio-economic and ecological sense. This is why we decided to combine the expertise of Austrian and French architects and our local partners in Mayotte for the new construction of the Lycée Tani Malandi.

The large-scale project with space for over 2,000 pupils includes classrooms, sports facilities, a school restaurant with kitchen and a boarding school. The fluid combination of these functions creates an inspiring space for working, eating, sleeping and relaxing. Local materials such as bamboo, wood, clay and basalt integrate the school into the culture and nature of the island.

The individual functions of the school are divided into several buildings of different sizes, which are arranged almost parallel to each other and staggered in height on the flat hill.

Hotel tower and residences made of 75 per cent wood

The mixed-use eco-neighbourhood La Cartoucherie with a total of 3,100 flats, 6,000 m² of commercial space and public facilities such as schools, sports and leisure facilities is being built on a former industrial site on the left bank of the Garonne. We built the "Wood'Art" complex there with an eleven-storey hotel tower and two residential complexes an award-winning project as part of the national Adiv'bois competition in France. The buildings are 75 per cent timber construction a topic that is also very important in France. Wood is used wherever it makes the most sense.

The hotel and the residential buildings were constructed from two-dimensional, prefabricated timber modules. This construction has a very positive effect on energy performance and the indoor climate, while also reducing waste and speeding up construction times an essential prerequisite for building in densely populated cities.

A high-rise on a traffic island

DC Tower 3 on the Donauplatte (Danube plate) in the north of Vienna completes the ensemble with the two office towers DC 1 and DC 2, designed by Dominique Perrault, and offers 832 flats for temporary living. On several levels, the 100 metre high building is connected to the existing Donaucity quarter and the transport network by public squares and paths and forms the end of the previously incomplete Carl-Auböck-Promenade.

The protrusions of the three-dimensionally shaped and aluminium-clad façade elements find their counterpart inside in cosy alcoves that frame the view of the Danube and the city from the rooms. Aluminium slats structure the façade in the base storeys, while the tower is clad in aluminium panels from the ground floor upwards.

The narrow plot – little more than a traffic island, surrounded by Wagramerstrasse, the motorway slip road and the underground line – presented us with major challenges during the planning phase. However, the attractive location on the Danube with a view of St. Stephen's Cathedral and the prominent neighbourhood with UNO City, the Perrault Towers and Harry Seidler's skyscraper were worth taking the risk.

Like a city on a small scale

The renowned Festspielhaus on Lake Constance has been modernised, reorganised, greatly expanded and developed into a multi-purpose cultural, social and economic centre of international standing. The project impressively demonstrates how an unsightly conglomerate of buildings from the late seventies can be transformed into clearly structured and graceful architecture.

Thanks to extensive and precise pre-planning and prefabrication, we were able to realise the complex construction work, carried out in several stages, without interrupting operations. In the first stage, which lasted until 1997, the workshop stage, lakeside foyer and lakeside studio as well as an administrative wing were built.

In 2005, the festival theatre was renovated and extended. Guests are now greeted by a light-flooded glass façade and an inviting forecourt instead of grey concrete. The main foyer, Great Hall, foyers and lakeside gallery were redesigned and the building's technology was modernised. From 2022 to 2024, we refurbished the outdoor grandstand and Seebühne (Lakeside stage), updated the technology of the workshop stage and built a new multi-purpose building.

Respectful conversion of a listed building

The Zacherlhaus, designed by Otto Wagner's student Josef Plečnik, is one of the most important Viennese architectural monuments of the early 20th century. The conversion of the listed building into a bank branch required extensive interventions on six floors – from technical rooms in the basement to the customer hall on the ground floor and offices on four floors. In addition, the roof terrace on the rotunda was made accessible for the first time and can now be used for events.

In 2023, the customer hall needed to be extended. We converted the adjoining corner premises, which had previously housed a shop, in the same design. This gives Hypo Vorarlberg a somewhat broader presence on the street and more urgently needed space.

We developed a coherent overall concept that complements the existing building to create the Omicron Campus.

Six very different courtyards now zone and illuminate the new three-storey square. On the ground floor, foyers, meeting, storage and laboratory rooms adjoin the green atriums. The offices on the two upper floors can be adapted flexibly to the team sizes thanks to easily removable partition walls and benefit from the view outside.

Timeless beauty in wood

On a mountain meadow above Dornbirn, we built a timeless, beautiful house in wood and glass. Conscious of tradition and at the same time straightforwardly modern, it shows respect for the landscape, but without any false rustic flair. With its clear cubature, flat pitched gable roof and wooden outer skin, the building blends into the surrounding landscape with the same respect and restraint as the traditional farmhouses in the region.

Wood is the dominant material, inside and out. The floor-to-ceiling glazed rooms are orientated towards the south-west with beautiful views of the countryside and the valley. Exits at ground level lead to the loggia in front, which is adjoined by the garden.

A house for energy and environmental education

The "Rubina" multifunctional building on the site of the former Nibelungen barracks in Regensburg is a new centre for the care and education of young people. The complex is divided into two square buildings. Surrounded by spacious outdoor areas, they stand freely on a shared platform and allow views of the surrounding greenery.

The first building houses the energy education centre, offices for the energy agency and scientific rooms for MINT for Kids. The second houses a kindergarten. Rubina is an acronym for Regensburg, Umwelt, Bildung, Innovation und Nachhaltigkeit (Regensburg, Environment, Education, Innovation and Sustainability) and its facilities absolutely live up to this name.

Growing from the centre

The rural area, the village, needs effective concepts for positive development and a viable future. The small Salzburg community of Moosdorf should grow from the centre outwards. With the "Innviertlerin" project, we are expanding the existing village structures. A food market, a hotel with a bakery and café, restaurants, flats for singles, couples and families as well as offices and surgeries all contribute to a lively village life.

The concept consists of five houses of different heights loosely grouped around a lively "village square". From north to south, the functions gradually shift from public to increasingly private use.

Dense programme under a dynamic shell

In small towns like Cormeilles-en-Parisis, 17 km north-east of Paris, club sport plays an important role in social life. The new sports centre offers local teams, recreational athletes and schoolchildren optimal training and competition conditions. The dense programme includes a competition hall, multi-purpose hall, dojo and fistball room. Open and protective at the same time, the uniform and dynamic shell harmonises urban and human scale.

With its flowing silhouette, the sports centre makes a striking statement at the entrance to the town, and yet blends unobtrusively into the loosely built-up residential area. Thanks to the lowered playing field, we were able to keep the building height moderate. Cleverly placed kinks modulate the length of the building, and a simple twist turns the ribbon-shaped roof into an attractive canopy that extends protectively over the entrance and forecourt.

The planned building offers space for production and storage areas as well as office space for around 140 employees on two basement floors and four upper floors. The special feature of the b2 Development Centre is that it is designed to grow with the company. If required, the first floor can be extended, adding 40 workstations to the offices on the second floor.

Living and working in Feldkirch

In Feldkirch Altenstadt, the former Hilti & Jehle site is being developed into a liveable and future-oriented living space - the "Viertel vor Feldkirch" neighbourhood. Covering an area of almost 30,000 m², the neighbourhood combines different living environments such as housing, living and working and thus conveys a dynamic, urban lifestyle. The diverse mix of uses and high-quality architecture make the neighbourhood a living space with a high quality of stay and a meeting point character for generations. The flexible utilisation programme can be adapted to future requirements and developments at any time, thus ensuring a long life cycle.

We have set up a BIG ROOM for the integral planning process. The special thing about the BIG ROOM is that not only the architects, but also the clients, specialist planners and contractors sit together in a physical space on site. This means that all steps can be coordinated quickly and easily. With our integrated way of working, we achieve better quality, fewer change loops and more efficient processing. This way of working is also the subject of our dossier "Working like yesterday, planning for tomorrow?"

Supermarket with social housing on top

In view of rising land prices that are unaffordable for social housing, we have developed a multifunctional urban building block with prototype character. The special thing about this project is that it is not social housing with an integrated supermarket, but a supermarket with social housing on the roof.

The three-storey complex includes 60 flats with private gardens, terraces and balconies and blends harmoniously into the small-scale development of the neighbourhood. Above the plinth, a façade band with generous openings serves as privacy and noise protection for the flats above. The east-west orientation of the four rows of flats creates a varied interplay between residential courtyards, arcades and the gardens.

Versatile holiday home for families

The REKA holiday village is located on a gently sloping site in the foothills of the Alps in eastern Switzerland. The 50 flats for families with children in the three L-shaped wings are built to the Minergie-Eco standard using local timber. They are docked in a comb-like fashion to four interconnected communal buildings with reception, event rooms, indoor pool, kindergarten and petting zoo.

Like a buffer, they shield the residential buildings and inner courtyards from the noise and dust of the cantonal road. A subway provides safe access to the play areas and the swimming area on the Urnäsch river.

Working below, living above

The Belval site, which covers around 120 hectares on the territory of the city of Esch-sur-Alzette and the municipality of Sanem, is regarded as a pilot project for the conversion of former steel sites in Luxembourg. On Lot 40, we are building a striking mixed-use complex with attractive space for offices, shops and services at the base.

Above this, the residential storeys are positioned in such a way that in the centre the park-like roof of the base forms a quiet, green inner courtyard for the residents. The interplay of different heights and window openings creates an exciting, rhythmic structure and at the same time ensures a strong urban character.

Ecological material, economical construction

The multifunctional sports hall forms a community centre in the heart of Bon Lait, an urban development area in Lyon. The spatial programme consists of a triple sports hall for various ball sports, a training hall for martial arts, dance and gymnastics as well as a meeting room and offices. The sports hall is available to schools, clubs and amateur athletes in the neighbourhood and is a meeting place for the local population throughout the week. The building is impressive proof of the effectiveness of timber architecture in an urban context.

It is not only renewable raw materials such as wood and straw that make the building sustainable. It is above all the interplay of ecological materials, economical construction, uncomplicated building technology and comfort that has been achieved here with optimal utilisation of daylight, natural ventilation and surfaces that appeal to the senses.

Distinctive, kinked silhouette

A swimming pool with a 25-metre and practice pool as well as a three-court sports hall including a bouldering wall, sprint tunnel and spacious ancillary rooms - the construction project of the municipality of Gräfelfing at the Lochham school campus involves a lot of volume. We considered how this volume could be organised in the most compatible way for the surroundings and in the most functional way for the users.

The result is a single-storey, two-part building with a green flat roof, whose striking, kinked silhouette blends harmoniously yet confidently into the surroundings. The indoor swimming pool and lowered sports hall are arranged at an acute angle to each other and connected by a triangular, shared access area.

The asymmetrically cantilevered roof emphasizes the entrances and guides visitors into the hall. Narrow vertical slats accentuate the timber façade and act as privacy and sun protection in front of the generous glazing.

A multifunctional district centre for Taxham

Together with the Europark shopping centre, the three circular interwoven buildings form the future district centre of Salzburg-Taxham. The base houses restaurants, a health centre, sports and fitness areas as well as a bank branch and police station. At the same time, it serves as a base and access point for the newly designed SPAR centre.

Together with the differentiated offerings of the base, the neighbourhood square forms a lively, communicative space that invites people to linger. The open pathways on and through the square, together with retreat areas and niches, create ‘favourite places’ for a variety of interests. A free-standing pavilion with shops and a café also provides covered waiting areas for the bus station.

Work, research and living

For Siemensstadt 2.0, we created a coherent masterplan for the 70-hectare industrial site in the west of Berlin, part of which is a listed building. The aim was to develop a sustainable neighbourhood that meets high standards of architectural quality, sustainability and economic efficiency.

The closed industrial area is to become a lively neighbourhood with research and production facilities, 2,750 flats, a hotel, shops, restaurants and cafés, schools and kindergartens as well as spacious leisure areas. The residential component will be concentrated in three areas of the site. The typological diversity of its building structure and the mixed ownership of rental flats, owner-occupied complexes and construction groups ensures its desirable social diversity of residents.

From the hammer mill to a nature show experience

A former hammer mill from the 19th century was turned into a natural history museum and urban garden after it was closed down. We have added new buildings and extensions to the remaining historical parts with great sensitivity, taking up the industrial character of the existing building and interpreting it in a contemporary form. The project on the Rüsch-Werke site successfully represents the combination of modern architecture with historical buildings and the transition of an industrial site to public use as a museum and urban garden.

To ensure that the premises meet the requirements of a modern museum operation, we have constructed several new buildings and extensions to the existing buildings: Technology and storage rooms and offices at the turnery, a demonstration hall between the turnery and foundries, offices and exhibition areas at the new foundry. The industrial character of the existing buildings is reflected, among other things, in the Corten steel of the external facades.

A large event hall with piazza

The location of the TuFa at the boundary between the historic city centre and loose development with individual solitary buildings requires a sensitive integration, but also a self-confident, representative formation of the site. We have broken up and subdivided the lengths of the large new building volume with kinks and jumps in height. A piazza with generous steps welcomes visitors and leads them to the polygonal forecourt of the interim entrance. The main entrance remains at the rear of the building.

The new and existing buildings merge to form a homogeneous ensemble, united by structure and colour. The new building is clad with a rear-ventilated construction of anodised standing seam sheet metal – a nostalgic reference to the existing theatre building in Trier. The building opens up by sliding, folding or lifting the façade shell, revealing behind it insights, light or information and thus interacting with the surroundings.

An internal street will provide access to all the uses of TuFa 2025 (large event hall, small hall, textorium, access to the workshop rooms) and improve orientation for users. This also makes it possible to use the rooms in a flexible way and hold several events at the same time.

Residential concept of stacked bungalows

For this small residential complex in a quiet neighbourhood of loosely built single-family homes, we arranged two elongated cubes slightly offset from each other. This provides both the necessary privacy and unobstructed, expansive views. The architecture skilfully plays with the contrast of raw concrete and fine wood structure. The façade is extensively glazed and the balconies provide structural weather protection and thermal insulation in summer.

The emphasis on the horizontal, the contrast between closed and open areas and the targeted use of daylight create an unobtrusively elegant effect. To the north, an inviting, semi-public courtyard opens up the complex, while the play area is located to the north-east, separate from the private areas. The living concept is reminiscent of stacked bungalows that can be "walked round" on three sides.

21 flats instead of a detached house

Where there used to be a detached house, we have built 21 flats on the 2,400 m² plot. The three cube-shaped structures of the residential complex on the outskirts of Feldkirch blend harmoniously into the loosely built-up neighbourhood. The individual quality of living and the relationship to the landscape were key aspects of the planning.

We achieved the optimum ratio of built-up area to living space primarily through the shared central access platform for all three houses. This also allowed us to preserve the old trees and a large part of the existing garden. This was also a condition of the previous owner for the sale of the property.

A shield with a signalling effect

The elongated, 100-metre-long structure of the supermarket forms a large shape that clearly stands out from the neighbouring buildings. Unmissable, a building-length sign made of perforated trapezoidal copper sheeting, large parts of which can be lowered mechanically, signals "open" or "closed" to the customer. Behind the finely perforated screen, which also shades the largely glazed south front, the space is shared by the sales hall and a covered car park at ground level.

Our most important architectural means included economical construction, a clear floor plan, carefully defined proportions and the special effect of the perforated shield. This building is therefore also an example of how less is often more.

Striking head-end building redefines the square

The modern, sustainable office building on Zurich Central, one of the most important transport hubs in the city centre, is a chance to redefine this square in terms of urban development. Our design for the striking, trapezoidal head-end building forms the prelude along two important transport axes as "house on the square".

The grid-shaped, ceramic-clad façade appears elegant and simple, with refined details such as differently bevelled window reveals. Wide, deep supports compensate for the large, floor-to-ceiling glazing of the two-storey plinth and lend it a stability that inspires confidence. The three-part, narrow square façade with the recessed attic storey gives the building on Central a distinctive appearance.
