The construction of a new building for pool attendants and the infirmary replaces a temporary facility that had become obsolete. Designed entirely in prefabricated wood elements on a concrete base, the building meets current safety standards and the growing needs of users, and has been designed to high energy standards. The independent, ventilated roof structure is laid on the pavilion volume. The facades are clad in pre-grained spruce clapboard, which blends seamlessly into the wooded surroundings. Inside, the materials used are white-stained OSB.

Solar thermal panels are installed on the roof to supply domestic hot water. The installation of bifacial photovoltaic solar panels on an independent light structure, designed to provide a shaded area for users, produces sustainable energy, covering the energy needs of the filtration systems and technical premises.
