Program: Near Anza Borrego Desert State Park, Richard Orne designed a single-family residence for himself and his designer wife, Susan Hancock, in one of only two “dark sky” communities—areas designated to minimize light pollution and preserve the natural darkness of night skies—in the U.S.
Location: Indian Head Ranch, Borrego Springs, California
Solution: The house is perched on a gentle slope, where the flat desert floor begins rising toward the Santa Rosa Mountains, just 10 miles to the east. The structure’s linear, elongated layout and floor-to-ceiling glazing aims to maximize contact with the outdoors and views of the dramatic landscape. Living room, dining room, and kitchen open to one another at the center of the house, with bedrooms and bathrooms at either end.
Construction and materials: The rigid steel frame structure falls somewhere between pre-manufactured assembly and conventional custom construction. Elevated for minimal site impact and maximum water flow, the house has a double roof for enhanced heat deflection with a 6kW photovoltaic array. Ceiling cassette mini-splits allow for heating and cooling in only the occupied areas of the home, which is clad in double-insulated low-e glass and cement fiberglass panels with a rainscreen application. Susan Hancock designed all interior colors and finishes, and cork panel flooring is used throughout.
