Frank Lloyd Wright's Freeman House, built in 1924, was designed as an experimental prototype of mass-produced affordable housing. The home's richly patterned "textile-block" exterior was Wright's invention and is the most famous aspect of the home's design. Situated on a dramatic site overlooking Hollywood, Freeman House is built with the world's first glass-to-glass corner windows. Dancer Martha Graham, bandleader Xavier Cugat, art collector Galka Sheye, photographer Edward Weston, and architects Philip Johnson and Richard Neutra all lived or spent significant time at this house, which became known as an avant-garde salon. The house is currently closed for restoration; call ahead to see if it's open.
