Located in Paris, the project occupies the attic floor of a XIX century building. It is a tall space (5 meters at the ridgeline) under a high-pitched roof held up by two large wood trusses, and well lit with windows on both the front and back walls.

In order to satisfy the client's desire to keep the exceptional volume of the space open, the architects placed all of the service functions, such as the kitchen, dressing room, closets, and bathroom, into ne compact, alomst free-floating, container. The "roof" of this container becomes the slleping loft. Importantly, the container stays clear of the front and rear walls and the ceiling, just missing the bottom chord of oneof the trusses. The result is a dialog established between the two realms: the empty enveloping volume and the compressed utilitarian box.
