Wright designed and built a number of houses in the Hollywood and Los Feliz districts of Los Angeles in the mid- to late 1920s. Lloyd Wright's first residential commission, the Taggart House was built for the mother of his second wife, Helen Taggart, a registered Los Angeles Historic-Cultural Monument located next to the city's Griffith Park. Another significant project was the hillside house for the manager of film star Ramón Novarro, and then a renovation and enlargement when Novarro himself acquired the residence. The dramatic and theatrical Mayan-inspired John Sowden House has become his most iconic structure and is usually regarded as his best work. He also designed and built his own home with a ground floor studio and second floor residence, using concrete blocks, in West Hollywood in the 1920s.
