The proposal starts from the premise of providing an open space protected from sun and rain. Located on a pre-existing plateau, the building was designed in relationship to the existing house, activating the intermediate space between them. The cover plane slopes towards the valley, bringing into the inner space the presence of the slope. Below the coverage is located a kitchen associated with a dining space, a sauna and a space of covered area in which the vegetable soil remained. The association of different structural systems takes place in order to explore the characteristics of each.
