An inhabited double skin overlaps the terraces to keep the continuity and fluidity of the volume. It is the alternation between the double glass façade and vegetation that protects the interior life from external nuisances (heat, noise etc., while keeping the interior largely open to the landscape: urban and natural. The terraces shelter mixed usages such as meeting rooms, leisure spaces and even vegetable gardens.

The second skin animates the facades of the building which becomes a natural prolongation of the topography of the Coteau. The skin of the building evolves with the change of seasons creating a living landscape.

As for the internal organization of the building, the various programs articulate themselves along the interior patios, another element that adds to the human and ecological biodiversity of the project. Connected both to the urban environment and to the park, these greenhouses benefit from controled climate conditions. The proportion, proximity and relationship of interior spaces, and the way they are articulated, defined and connected through double heights and passerelles, facilitate the communication and movement.
