The small hospitality facilities, on piles or on the island, are composed of two elements: an ‘abstract’ white cube, open with a large glazing to the sea with the reserved pools, is topped by a wooden roof in the form of a vault or a seashell, a protective presence independent of the part below. This solution, besides producing a complete figure, creates a system of natural cooling and ventilation, preventing direct sunlight from heating up the residential capsule. The curved roofs, not only for the cottages, are shaped to suggest marine life forms (turtle shells, the magical forms of manta rays, the smooth surfaces of whale sharks, the spirals of seashells) are joined by flat or single-pitch roofs for some of the shared structures at the center of the island.
In the latter case, the roofs are used for solar panels, as well as for hydroponic cultivation of foods, cutting down on the need for shipping of provisions. The arrival dock and mini-club are distinctive architectural features, two tensile structures in white ETFE fabric following the line of a steel support skeleton.
