Tucked into the desert on a quiet side street off Campbell Avenue, the Module House by architect Robert Swaim sits on 2.2 acres in the Catalina Foothills. It is a rare Limited Edition Series residence, the only realized example of Swaim's modular concept, with sweeping mountain, city, & sunset views. The home was featured in Sunset magazine; the original owner served as Vice President & Editor at Sunset at the time. An honest material palette was carefully carried throughout: concrete, masonry, and glass, with a clear expression of structure. A central spine organizes volume and movement, while vaulted ceilings and expansive walls of glass connect the interior to patios, pool, and desert. The boundary between inside and out is continuous. Floors, framed views, & walls extend out into the landscape. The landscape reciprocates as shadows and reflections, the desert beyond is drawn into the rooms. The open plan of public spaces brings in natural light throughout the day and supports easy living between indoors and out. This exceptional home offers 3 bedrooms and 2.5 baths, living and sitting rooms, dining, owned solar, and a 2-car garage. The private main suite includes an additional sitting area, walk-in closet, a generous bath, and direct access to the pool patio for evening swims. Recent improvements include central HVAC, a tankless water heater, a new roof coating, a new driveway, and updated hall bath and powder room. See the improvements sheet for the full list. This is a rare opportunity to live in an architecturally significant gem, well situated in the Catalina Foothills. The sale of this property also includes an adjacent vacant lot. Please note, this property is not located on the loud + busy Campbell Avenue.
