The ground floor building is functionally configured on two levels with a height difference of 2m that communicate with an internal staircase. The lower level is organized around an atrium around which are placed functions served in a single space such as reception-meeting room, entrance & kitchen-dinning room, while on the upper level functions of isolated spaces are placed.

The facade synthesis is based on the composition of vertical levels & volumes which, with the appropriate differentiation of cladding materials, harmonize with the natural environment while giving an element of identity to the building. The atrium around which the ground floor building is organized, as well as its large openings, makes the interior a seamless continuation of the exterior.
