The existing topography of the site is logically evolved westwards as a plateau. The plinth for this plateau is the gym, which is recessed underground in a large part. The flat roof of the gym is used as a sports field. A three-story building represents a closed front to the noisy Zurcherstrasse and protects the schoolyard from street emissions. The basic idea of the new buildings is the logic progression of the existing structures, completing the pattern of alternating open spaces and built volumes. The surrounding urban context with villas and small gardens is reflected with the realized pattern.
All buildings are accessed by the common platform of the schoolyard with the sports field. For use by non-school organisations, the gym can be accessed by a separate entrance at the far end of the site.
All class rooms are oriented south towards the schoolyard and the great scenery of the Burgweiher area. The dominating materials on the inside and outside are fair faced concrete, room-high glazing and larch wood. The classrooms represent a cozy and warm atmosphere using wood for furniture and floors, whereas the corridors and stairs show a hard surface using concrete.
The whole building complex is the first Minergie-ECO-certified school in Switzerland. This means not only the reduction of energy consumption by using the latest isolation materials, regenerative energy sources and photovoltaic elements on the roof. The supplemental ECO standard requires, that all materials used for construction must not contain toxic substances, solvents etc., all wood must originate from nearby forests or must be certified FSC and the latest guidelines for worker protections must be regarded.
