Used to describe the modernist movement in architecture as it evolved in California, specifically Los Angeles and the area surrounding it, from the 1930s through the 1960s. Hallmarks of this style are attention to indoor-outdoor living, open plans, rectilinear structures often constructed with steel frames, and extensive use of glass. The term is most often used to refer to the Case Study House Program initiated by John Entenza in 1945, and to modernist residential structures in general. Architects associated with the style are Richard Neutra, Rudolf Schindler, Charles and Ray Eames, Gordon Drake, Albert Frey, John Lautner, Pierre Koenig, and Rafael Soriano. Public perception of this movement is commonly attributed to the photographs of Julius Shulman, as published in architectural and interior design magazines during the 1950s.
