The city of Zurich is planning an extension to the Entlisberg school site with nine classrooms, two kindergartens and catering areas. Rooms for the Zurich Conservatory music school and a single sports hall are also planned. The existing school building from 1947 is a listed building and part of the inventory of protected gardens and grounds.

The new building will be integrated into the park as a pavilion-like structure and will be modelled on the existing school building in terms of height and type. At the same time, the interior of the new building will have a room layout that corresponds to modern forms of learning and teaching and allows for an arrangement in clusters. A wide, covered break room on the ground floor connects the northern entrance with the southern school garden.

The new building restructures the southern part of the school complex, clearly organises the rooms and remains open and permeable. The outdoor space, existing building and new building form a coherent school complex that can still be read and experienced as a garden school.

Planned as a timber-clay hybrid construction, the new building enables a high degree of prefabrication and uses clay as a thermal mass for summer heat insulation and a pleasant indoor climate.
