New Building Kantonsschule Zimmerberg

Programme The new construction for 1200 pupils is an ensemble of three differently proportioned buildings:
a multifunctional, semi-public building with a canteen, assembly hall, gymnasium and sports ground on the roof,
a five-storey building for general teaching
and a four-storey building for specialised classes.
An open structure serves as a connecting element between the three main entrances.
