The project focuses on quality and inexpensiveness. A public building cannot symbolize a waste of resources, yet, considering its public function, it cannot lack architectural, urban and space quality. The original task was to renovate a pitched-roof shed. The first challenge was to convince the client to have a new building built-up with the same amount. The second one was to harmonize it with the city and the road, although the building had rather small dimensions: the building creates the urban scale of the intervention setting up his relationship with the street front through the articulation of the common spaces.
