Located on the edge of a half-residential area, half-country-side area, this high school created by Claude Parent stands out by his modular construction method and by an inclined cube-shaped sculpture, in concrete, originally placed in the heart of a large forecourt serving as access. The extension-restructuring project aims to preserve this strong signature. Thus, the existing buildings, with their specific ornamental elements, have been preserved, while the sculpture, a unifying landmark, is now enclosed in the centre of the reception hall. To redefine the complex, the bias was to set, along the main street, a wide facade topped by an inclined plane and punctuated by vertical blades – all concrete, in reference to the language of Parent. The organization of interior spaces is based on transparencies and fluidized circulation.
