The house sits atop a hill that overlooks the city; this was the main reason why we put the two bedrooms facing forward. The bedrooms are two separate volumes that intersect the main concrete "shell" of the house. The front and back are kept open with huge glass walls, both to let sunlight in at the back side, and to observe the view at the front.
Upon entering through the main door, the staircase welcomes you as it is the first thing you see. It divides the ground level into public spaces to the left, which include a guest bedroom and the living room, and service spaces to the right, which include the kitchen, dining and laundry rooms. The upper level is the private space, the two main bedrooms as well as an office/studio and a TV lounge are located here.
The construction materials used are basically three: concrete, steel, and glass. Even though it sounds like a poor solution for the cold climate of Chihuahua it is well insulated with extruded polystyrene panels on all the exterior walls and roof. The windows are double-paned and protected by passive systems.
