The site of Los Terrenos is nearby Casa Ventura, is located in a residential zone adjacent to the southwest side of Monterrey, it’s a highland forested zone. The house program is fragmented according to each component’s function and role within the site; but they are all enclosed in a perfect square in the general plan. Each volume located in the corners, surrounding an organic shaped pool. The landscape strategy aimed to respond and mimic the existing flora and fauna of the site in a designed aspect. The social area is on the first level, within a mirrored glass envelope that simultaneously reflects and contains the lush surrounding; the main room overlooks the tree tops; the other bedrooms are underground and built with clay and rammed earth in relation to the topography. The three program areas have a lattice that was designed to adapt according to different spatial connections and structural possibilities: it works as solid and permeable floor, screen partition, and structural wall, and as a semi- open wall that allows ventilation and sunlight bathing the interior spaces.
