Respecting the existing trees, the building has a glass roof with overhead lighting. At night, external spotlights create soft light. The four cabins have wood-effect walls, one of which is a glass panel with film. The floor and countertop are zigzag – designed by the architect – in blue porcelain tiles with veins. The interior geometry includes rectangular black sinks and round mirrors fixed by cables. The interior masonry has black and white stripes and the exterior has a brick finish, in a New York style.
