French firm Urbane Kultur expanded a “Tournesol” swimming pool in Lingolsheim, France. The dome-shaped swimming pool suffered from poor insulation and restricted space for changing rooms. Strasbourg studio Urbane Kultur was assigned to refurbish the building and add an extension at the side for new changing rooms and offices, freeing up space inside for two new swimming pools.

183 “Tournesol” swimming pools were built by architect Bernard Schoeller in the 70’s. These structures were enclosed in a dome, featured large sliding entries, and reflected an elegance that Urbane Kultur wanted to retain. The firm expanded the space within the dome by removing the changing rooms and adding two additional pools. The dome itself was also rebuilt – the exterior was covered in black rubber while the interior was covered in white canvas. A boomerang-shaped extension building clad in steel panels was also created to house the entrance hall, new changing rooms, offices and technical rooms.
Description by the architect. 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.
