Perched at the edge of a canyon and surrounded by sweeping 180 degree mountain views, this home is organized along a linear axis to take advantage of these views from every main room of the house. A butterfly roof tops walls of windows facing these views, but these windows also serve the purpose of allowing sun into the home to passively heat the space. Stained concrete floors serve as a heat sink for the solar energy which gets re-radiated back into the space at night. The home is constructed of Durisol® block, a green building block made of recycled products that is filled with poured-in-place concrete. Glulam beams, made of smaller wood members glued together, support a roof of SIPS (structural insulated panels). On the garage, solar hot water panels and photovoltaic panels provide hot water and electricity for the house.
