The building is a white raised box. The base is concrete, but the structure of the house on the first floor is made of wood. The wooden walls have been assembled in less than one week. This house achieves a high level of energy savings achieved thanks to an efficient insulation, orientation, the study of the arrangement of glass surfaces, but also by the surface / volume ratio of 0.961, an intrinsic feature of the compact design of the house, where surface dispersant contains very little volume. Volumes pure and sincere, without decoration or camouflage.
