Only three of the Arts & Architecture Case Study Houses were built outside Los Angeles, and those three formed a united concept. The Triad Houses in La Jolla, a seaside suburb of San Diego, share a single driveway, motor court, and design vocabulary, while being created to meet different needs.
In keeping with the Case Study mission, all three houses used open-plan design, affordable modern materials (such as aluminium and concrete with wood frames), and plenty of glass to create a fresh and open mood. The emphasis was on strong geometric forms, careful detailing, horizontal lines (with perfectly flat roofs) and – this being the Californian coastline – dramatic views and outdoor living space, creating the illusion of more interior space than was actually present.
