Half hidden, in the skirt of a precipice, its spine is curved slightly.  Its body is sheltered, and is situated to fit into its natural surroundings. The ribs start at the level of the public throughfare, covering the bay of secondary places below and ascend slightly, extending over the primary space completely. Each rib serves several uses: it gives shade to the parked automobiles, brings light to the sport fields, and it supports oriented solar panels. The access is announced by the entry facade on the north edge of the building, fronted by a traffic circle organized around circular perforations which bring light to the floors below. The exiting can be realised, at a moment, by the multiple exits located in the lateral glass facade facing the park. The surfaces of parking are placed in the less attractive areas, next to the access roads. The transverse from street to the green zone (to the west of the site) is found in stairs that follow the countours of the existing topography and create a wide clearing at the neck of the structure.  The green zone to the west of the edifice is maintained as an existing continuation of national reserve for the play and practice of sports, and extends from the site, to the ocean beyond.
