The Solar Umbrella House is a private residence in Venice, Los Angeles, California, remodeled using active and passive solar design strategies to enable the house to function independent of the electrical grid. The design was inspired by Paul Rudolph’s 1953 Umbrella House for Philip Hanson Hiss III's Lido Shores, Sarasota, development. Originally a small 650-square-foot (60 m²) bungalow, the owners added 1,150 sq ft (107 m²) in 2005, remodeling it in such a way that the house is almost 100% energy neutral.
