This building is a car dealership built on a well-exposed plot, but very difficult to exploit: it is very close to a main crossroads regulated by a roundabout, with a shape approximately similar to a "quarter-ellipse". This mean that the shape of the building has been adapted to the shape of the plot of land, with a long glass wall facing the street, and the closed service volumes (stairs, lifts, toilets) placed in the rear part of the building. To improve at maximum the interior spaces, the horizontal structural slab is suspended by rods, which allow to obtain a five-hundred square meters exhibition hall without internal pillars. The steel rods are joined to large iron “portals” (beams type: IPE 1444) that transfer the weight to the ground and to the central core made of reinforced concrete. The manteinance garage is placed in the basement, and the exhibition room and the sales offices are placed at the ground floor; at the first floor there'll be some office spaces, with an opaque external cladding, to amplify the feeling of a heavy mass suspended over the void.
