The Centre for Mental Health in Böblingen-Sindelfingen is designed as the prelude to a “green centre”. The guiding principle of the design is to create an ambience in close contact with nature that is conducive to the quality of stay and the recovery of patients. A light-flooded main corridor runs through the building, accompanied by two inner courtyards. Therapy gardens are arranged on all levels, which also serve as retreats. Two-storey therapy loggias create a natural transition zone to the surroundings. A barrier-free roof garden rounds off the concept of direct connection to nature. With its light-coloured clinker brick, the transparency of the floor-to-ceiling glazing and the light-coloured wooden elements, the façade has a natural and inviting effect.
