Max Azria of BCBG: Azria's 60-room colonial-style mansion dates to 1924 and was designed by Paul Williams, a celebrity favorite at the time (he created homes for Frank Sinatra and Lucille Ball, and designed the Beverly Hills Hotel). The house once belonged to I Dream of Jeannie creator Sidney Sheldon. Pieces such as the light fixtures and poufs are a nod to Azria's North African heritage.
