The unitary roof expresses a unitary and modest intervention. It faces the avenue, and the roof overhang provides an interface between the building and the open space, a generous space for workers, walkers, and athletes. The building's approach is to present the workspaces at the forefront, on the façade, and to turn them into a “high-performance machine” that tends towards autonomy and allows for an educational role for neighboring schools. The workspace therefore faces the avenue via large sliding doors. From this unheated space, the technical and “dirty” functions are organized in an elongated volume on two floors, with the collective and office spaces upstairs. In this way, a clean interior world for the workers unfolds, visually connecting the workspace, offices, and cafeteria, away from the other activities of the busy sports site. The heated parts of the program thus benefit from a cross-cutting quality, between the view of the wooded ridge and the covered workshop and garage space.
