Wright's only Usonian-style home in Southern California, designed and built in 1939 is a small, one-story residence of about 1,200 square feet - with deck that seems almost as big as the house itself. It is constructed of brick and redwood, in contrast to the concrete, "textile" block houses he designed in the 1920s like Hollyhock House and the Ennis House.
You can see a 1947 photograph of it here.
