We have decided to transform the Léopold Bellan gymnasium, located in Bry-sur-Marne, into a municipal swimming pool. We have decided to create a space for residents, a shared common place, a green and spacious venue for entertainment. Combining elements of education, relaxation, calm, life and leisure, this mineral space blends into the outer landscape. The swimming pool will therefore be designed and built as a continuation of nature. The colour green, associated with calm both symbolically and literally, will carpet the entire space, from the walls to the framework, in the style of Eiffel. The project therefore endeavours to draw citizens in to experience a collective, bucolic change of scene.
