The House In Chihuahua is part of a golf club community in the desertlike northern region of Mexico. The dwelling was designed to accommodate the special climatic circumstances of the area: in winter temperatures can fall to minus ten degrees Celsius, while in summertime temperatures can rise to above forty degrees Celsius. The differences between daytime and nighttime temperatures can vary by as much as twenty degrees. To balance the extreme temperature differences, we partially buried the house into the mountain slope to take advantage of the soils thermal mass. The colder soil around the house absorbs heat accumulated during the day, and at night the ground gives off heat to the building.
