Equipped with a basin and a shower, an existing piece of water is enlarged taking the surface on the living room. Around, uprights and bastaings (50 x 150) form the framework of the cube. Above, the installation of a vertical structure in lightweight materials is the room space. In order to increase the ceiling height and comfort on the mezzanine, the attic is recovered.

Ideal for mezzanines, the wood floor is both economical and very light. Although its installation is fast, it is nevertheless rather delicate and offers little protection against noise, water and fire.

The OSB decking is laid without coating, to lighten the whole. Nailed to the joists, it allows a good distribution of the load.
