Bertha-Benz-Schule in Sigmaringen

The new school centre, which offers several types of vocational training, is located on the northern outskirts of Sigmaringen at a prominent location at the intersection of two major access roads and in the immediate neighbourhood of the district hospital, various other schools and an extensive sports complex.
The large shape of the clinic on the neighbouring hill calls for a striking form with a strong presence. A circle can achieve this, together with a long building block as a supporting backdrop, which anchors the ensemble naturally in the topography of the gentle slope despite its enormous dimensions.
The circular shape creates a centre that is clearly recognisable from all public sides. It provides orientation and enables intuitive navigation. The centre of the circle forms a campus that is centrally accessible from all directions. It serves as a forecourt in front of the main entrance, as an event courtyard and festival ground, as a meeting place with an attractive open staircase and a view of Sigmaringen – in short, as an attractive inner courtyard that invites visitors to linger and communicate.

The ring contains the general teaching areas. The building wing running parallel to the contour lines houses the specialist departments and their workshops, among other things. Green courtyards provide natural lighting and pleasant views from the interior rooms.
To the north, the workshop and, near the bus stop, the multi-storey car park with its green façade are connected. The centre of the building can be reached without any overlap between the respective movement and traffic flows (foot, bicycle, bus, motor vehicle).
The complex offers expansion options depending on requirements and the desired scope, both in the wing and in the ring.
Central functions such as the main staircase and sanitary areas are located at the intersection of both building sections. Both structures are clad in natural-coloured wooden façades with individual white accents. The wooden windows are structurally protected by canopies or folded-out façade areas.

Thanks to the reinforced concrete skeleton construction and load-bearing corridor walls in a circle, the drywall partition walls can be adjusted as needed and adapted to changing educational requirements.
The canteen and part of the common areas merge into one another, allowing these spaces to be used interchangeably as needed, thus avoiding empty rooms for long periods of the day.

The space-efficient design implements the room layout in an economical manner. Thanks to the building's shape and modular construction using precast concrete elements, the new building was very economical to construct and can also be operated economically.
The compact design, the use of renewable raw materials and the flexible floor plan organisation ensure long-term flexibility of use and guarantee a permanently sustainable building. The overall project meets the criteria for platinum certification by the DGNB and BEG 40 QNG.
