The new ’Collège du Verney’ in Puidoux (Switzerland) is situated on a site already partially occupied by a school whose capacity had to be increased. lt houses today the new program of the centre of child life, the swimming pool, the library, and two special classes. The new building consists of a lightweight metal structure on piles to meet the constraints of a swampy terrain. The arrangement of classes, which is based on a system of repeated modules on a regular grid, corresponds to a contemporary construction with a star shaped geometry which provides a maximum of facades.
