The ground floor transmits the idea of permeability between interior and exterior, thanks to the glass building envelope which favours crossed sight lines. So much in fact, that the views can go through the entire building. The first floor, its programme being of a more private nature, is configured as a less permeable and more abstract object, thus enhancing the contrast between both realities. The program is divided into four levels. The basement harbours the sport courts, gyms, fencing rooms, the dance studio and climbing wall, as well as the building services. The ground floor includes the citizen care areas, the meeting room, the cafeteria, the assembly hall, the fun-club and the stands for the multi-sport area. The first offers shelter to the library, the study room, the workshops and the offices of the social services of the area. Lastly, the swimming pools and changing rooms are on the second floor.
