Opaque sections draw the horizontal structuration of the building. The opaque walls of the gym and the squash fields differentiate due to their polished and pleated inox panelling; this material makes the façades look brighter and reflects the lights of the city. The multipurpose hall is situated on the 2nd floor. The changing facilities can be reached through two entrance halls both accessible form the main staircase, a hall on the upper floor and one on the level of the grandstands. The access for the public to the grandstands is situated in the central entrance hall.
