The building develops along the edges: western and southern of the site, which, together with the finishing elements of the outer space, determine a sort of atrium. Given the steep slope of the land and the desire to develop housing on two floors. We opt for a three-dimensional structure of screens and slabs of reinforced concrete that adapt to the topography by intervening at minimum with the earthworks. This monolithic structure anchored to the ground generates a horizontal platform, with an additional access level, where the living area is located. The pool area is located on this level in a flat area of ​​the site. The concrete structure is thermally insulated on the outside, with a smooth and flexible white plaster as a finish. The rest of the materials, walls, sidewalks … keep the same color emphasizing the unitary character.
