Roy and Patricia Hamma enjoy time in their living room, furnished with Charles and Ray Eames pieces. Once the couple's MHA 111 model was complete, Roy Hamma, an attorney, hired a professional photographer to document their newly built home, which was one of the original 30 “guinea pig” properties.

The MHA cooperative purchased 800 acres of land on the Brentwood side of the Santa Monica Mountains and worked with modernist architects A. Quincy Jones and Whitney R. Smith and structural engineer Edgardo Contini to build 350 homes. Only 85 houses from the original Jones/Smith plans actually saw the light of day.
