Nestled into the desert on 2.2 acres in the Catalina Foothills, the Module House by architect Robert Swaim was completed in 1988. It is a rare Limited Edition Series residence, the only realized example of Swaim's modular concept, with sweeping mountain, city, and sunset views. The home was featured in Sunset magazine; the original owner served as Vice President and Editor at Sunset at the time. A refined palette of honest materials 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.
