First, the authors of the project built a summer pavilion with an open terrace and a decorative pool with goldfish. Then they decided to warm the structure, so that Le Cristal could work in the winter. When the cold comes, the outdoor terrace closes the roof, and the pool turns into a light podium. All rooms of this interior smoothly flow into the exterior, forming a single whole with nature. The simplicity, asceticism of the forms and restrained palette with dull color accents make this interior a strict and status.
