The structure consists of eight truss portals; the stiffening is achieved by a continuous edge beam; Since the location does not enjoy good natural ventilation, at the tie beam intrados, a permeable non-woven fabric false ceiling creates a ventilated gap to avoid overheating during the hottest hours. The structure, in order to be removable, is made of profiled steel cladded by Cipo wood (materials chosen for their physical-mechanical characteristics). The entire structure rests on reinforced concrete slab. Due to the strong competition with other bathing facilities, for the interior design the idea was to characterize the structure with a style in opposition to that of the competition .So we opted for a modern, minimal style characterized by warm tones, with decorative high tech elements.
