Health Campus, Lausanne

The theme of the competition was a mixed- use development for a Health Campus in Lausanne. We chose an approach of creating a range of climatic zones, ranging from outside spaces over greenhouse-like in-between areas to regularly heated rooms in the centre of the buildings. In the lower part, big building blocks are created, while the part towards the forest is more open.

Area development, Speicher

Subject of the competition was a currently vacant site in Speicher, canton Appenzell Ausserrhoden. The site is owned by the municipality and will be provided for a residential development – a typical “urban sprawl task” in the agglomeration of St. Gallen.

As a spine of the development, we suggested a vertically oriented internal space that allows easy orientation for residents and guests. It also releases the view into the countryside and the village in regular intervals, in particular towards the village church. The buildings are arranged so that the views for individual apartments is optimized. Also, the buildings also are grouped into individual “homesteads”, improving identification for the inhabitants with their living environment and creating an address that is easy to find for visitors.

The design works with the three different typological principles Townhouse, Apartment, and Duplex apartments with studios. The focus is on family-friendly forms of housing. The bases of all buildings are constructed in solid concrete. The upper floors are clad in a horizontally structured facade of prefabricated wooden elements alluding to local building traditions.


We are looking for an intern in our office in Zurich, starting from now or by arrangement to work on building projects, competitions and studies ranging from the architectural to the urban scale.

The internship should last at least six months. Requirements are at least two years of architectural studies, high proficiency in drawing in CAD, image editing and graphic design, as well as good model making techniques. We expect precision, good communicative skills, proactive work, and the willingness to make an own contribution in a small and personal team.

Development Plan, Berne

After winning the Ideas competition in 2012, BHSF and Christian Salewski were commissioned with working out a development plan for the site. After having completed the first part, which will serve as a basis for submissions to potential developers, the second step will be taken by the end of 2014. The urban planning document is supported by more detailed studies about Landscape, the existing Güterstrasse 8 building, and Infrastructure.

On the site of around 22’000 sqm, 500-600 people will live and a further 200-250 people work upon completion. In total, 40’000 square meters of floor space will be realised on the site, which corresponds to a utilisation factor of 1.8. This means that the area will be built up with approximately double the density of the surrounding neighbourhoods. To serve this increased population, a supermarket as well as a kindergarten will also be realised. Currently, the former waste incineration plant is due for demolition.

A building that was originally not part of the waste incineration site will be re-used – the former storehouse of the Tobler Chocolate Factory, built in 1966. The high, deep spaces of this robustly constructed building have ideal preconditions for an uncomplicated transformation. Its upper storeys will mainly be converted into apartments in a large variety of types.

All buildings are grouped around a central courtyard. It will be enlivened both by the inhabitants of the area and the quarter, continuing the logic of the broad, mixed-use streets that can be found in the neighbouring industrial area.

School and Kindergarten, Mühleberg

The  school complex Mühleberg in Allenlüften is continued volumetrically, and the already heterogeneous group of characteristic roofs added to. Since children in Kindergarten and Primary School need “caves” (Hans Scharoun) that offer warmth and clarity, each group is offered such a space. They are accessed by individual cloakrooms, which further strengthens the sense that these are“caves”. The cloakrooms also serve as an acoustic barrier between classroom and hall. The floor plan enables a multitude of room configurations, and the building can also be adapted to changing long-term requirements.

The balconies expand the classroom space into the exterior and offer space to play, tinker and plant. The balconies also serve as a fire escape, shade the interior and cover the Kindergarten area on the ground floor. Energy consumption of the building is reduced through the compact volume and the avoidance of thermal bridges. Sun energy is collected passively by the façade and actively by photovoltaic panels. The generous windows also enable optimal use of daylight for the classes. Natural lighting is steered over sensors and supplemented by artificial lighting. Using these kinds of energy saving structures, radiators can be omitted.

Due to the special form of the roof, rainwater flow is concentrated in a few points. This combines with the rectangular form of the courtyard, which results in a roof geometry that creates a dialogue with the other roofs of the complex. The roof is also reminiscent of the distant Jura mountains.

The proposed building divides the plot’s uneven geometry into courtyard and garden as well as a circulation part outside of the perimeter. Through the position of the entrances, person flows as well as the representative sequence are subdivided in a functional and simple way. To coherently  integrate the building, which is in most parts a functional office building, into the parklike landscape, a hybrid type is proposed: A “working villa” with two stories over a plinth which is partly integrated into the soil. The underlying order, which is economical and strict, is integrated with nature and park through a second layer.

This is surprising, since these buildings represent a huge proportion of the buildings being renovated and are intriguing structures in many ways.

The technical college of Giessen-Friedberg will be renamed ‘The Institute of Technology Mittelhessen’ in the near future and aims to establish itself in the international field. For this, the campus is to be renovated and expanded. Since the renovation will take place during a general service, the existing buildings are to be the starting point of the urban concept. Great care was given to make sure that not only the final result, but also intermediate results would have good urban qualities. These building’s volumes are kept compact and economical, and parking spaces are positioned below the buildings, thus keeping the sealed surface small. Biking and walking are encouraged through the landscape with designated routes and the positioning of bicycle stands.

For the modernization of the single family home, a transformation of the house’s character into the present is proposed. The entrance, which presently is very cramped, is to be upgraded by moving the stairs into the interior and minimally modifying the position of the kitchen and the guest restroom. Through the introduction of skylights, the bedroom area is given an individual character. Dressing room and bathroom are united to form a generous area, separated through a glass pane.

In the back part of the house, a patio is added, which upgrades the working area in a relevant way, creating a concentrated and private atmosphere. A room lying further back into the slope can be used as a guest room or a home cinema and is equipped with an own bathroom. Since the building is normally accessed directly by car, the basement is upgraded as well.

The office floors are double loaded, divided by a generous corridor. According to the alignment and the exposition of the building the depth of the office space varies. The optimized service core is situated in the shaded east part of the floors. This compact layout allows the highest possible flexibility and the abandonment, from the energy point of view, of the suboptimal recessed floor.

It is assumed that the new gymnasium in Garching will play a fundamental role in the city’s public life as it is shared by the local sports clubs, almost all schools and individual citizens. Therefore the design clearly focused on the creation of a public building and site that reflects its importance to the city. The design of the landscape was very important to the success of the whole project.

The prefabricated steel framework is screwed onto the bedplate in a conventional span width, whereas the big span width of the sports hall is bridged by trussed beams. The stiffening is done by the floor slabs and the cladding.

BHSF is an architectural partnership based in Zurich, Switzerland that practices architecture and urbanism. It is the aim of the office to work in the full breadth of both of these fields, in practical as well as theoretical respects, in competitions as well as the everyday tasks, and on all scales.

Up to now BHSF has completed a dental practice in Duisburg/D, a multi-family house and multiple renovations and extensions in Zurich, a single-family house in Aldeburgh/UK, and an airplane hangar in Southern Germany. Current projects include a production hall in the Canton of Aargau, a villa in Zollikon as well as the transformation of the former waste incineration plant in Berne into a quarter for living and working. Since the foundation in 2005, BHSF has had success in several competitions, most notably the first prize for the parking garage in Wiesbaden.

Besides practical design and building activity, office talks on a broad range of subjects are held regularly in the office. BHSF is also active in teaching and research at the FHNW in Basel and the ETH Zurich.

Presently our team consists of 10 persons with seven nationalities and diverse educational and practical backgrounds. We speak English, French, Italian, Greek, Bulgarian, German, and Swiss German!

Johanna Willert concluded the Bachelor of Science (with international honour) in 2015 at the CTU Prague and the RWTH Aachen and has worked as an intern in offices in Prague and Wismar. Since August 2015 she works as an intern at BHSF Architects.


The counterpart to the practical work of BHSF is the publication and research platform Camenzind. While BHSF concentrates its efforts on Architecture and Urbanism, Camenzind works beyond the traditional boundaries of the discipline. This is based on the conviction that the architect’s task is not limited to producing the built environment, it is also necessary for architects to reflect on and research that environment and to work towards innovative ways of changing the way that society imagines and produces the built environment around it. Consequently, Camenzind and BHSF in one sense investigate the idea of Ernst Bloch’s “Concrete Utopia”, of bringing utopian goals forward pragmatically step by step.

Camenzind has been presented at lectures in Aachen, Berne, Vienna, Weimar, Zagreb, São Paulo and Zurich and taken part in exhibitions in London, New York, Milan, Berlin and Tokyo.

Benedikt Boucsein, Axel Humpert and Tim Seidel met while studying architecture at the ETH in Zurich. Their first collaboration was Camenzind Magazine #1 which came out at the end of 2004. After working for other practices they founded BHSF in 2007. The first projects they realized as BHSF were a dental practice in Duisburg and a multi-family house in Zurich. These projects, as well as the prize for the parking garage Coulinstraße in Wiesbaden were key to establishing the practical foundations of the office. Camenzind, which has developed into a platform for research and publishing, has grown alongside BHSF during the past five years.

Newsletter BHSF office talks

Since its founding, BHSF has organised and hosted an ongoing lecture series that takes place in the office every three weeks. For these talks the office space morphs into an intimate auditorium with seating laid out and a projector installed, the guest speaker gives a presentation on their chosen topic and this is followed by questions from the audience.
