Text description provided by the architects. 183 "Tournesol" swimming pools were built in France during the 1970s by architect Bernard Schoeller. These are rational objects, which offer amazing spatial qualities, natural light, high quality indoor / outdoor relationship with large sliding doors and a certain elegance in structural design.
The dome which is a self sufficient form makes any extension difficult. How to increase the capacity of such an object without altering the image?
The project preserves the simplicity the original pool: the extensions built over time are demolished, the area liberated by moving the changing rooms allow three stainless steel basins to take place under the dome.
The extension building houses the entrance hall, changing rooms, offices and technical rooms. It is independent of the pool hall, it is a "boomerang" that wraps the dome without touching it, without deforming it. In between, a landscaped patio organizes many transparencies between hall, pools and locker rooms.
