From Avenue Pierre Augier, the pool looks like a simple L-shaped “wall-building” containing the changing rooms and administration areas, punctuated by a largely glazed entrance lobby which is raised and marked by an overhanging canopy. The whole complex is placed on a “piano nobile” raised esplanade deck accessed by a wide staircase in continuity with the public space on the ground floor and the car park. The monumental staircase is extended on both sides by a terraced planted embankment. Behind the “wall-building” stands the separate volume of the swimming pool hall facing south onto the external artificial beaches and Mount Sainte Victoire. The entrance lobby extends through the building and opens onto the pool hall and the external beaches. The general volume of the pool features a succession of longitudinal rooflight girders of variable height to provide lateral daylighting and appropriate cross-ventilation in the changing rooms and the swimming pool hall. Observing Mount Sainte Victoire, there is a stark contrast between the strong red clay of the mountain’s base and the white limestone of its high “wall”. Therefore the walls of the pool are covered with beige earthenware tiles while the external ground is finished in ochre brick tiles. Outdoor spaces have been arranged in a harmonious relationship with the building and the surrounding landscape, and according to whether they are quiet or noisy. They consist of a quiet first area and a noisier second area at the southern end.
