Archibald Quincy Jones and Frederick Emmons partnership lasted from 1951 until Emmons' retirement in 1969. Their designs are reflected in some 5,000 of Eichler's homes, by Emmons' estimate. Jones and Emmons were awarded national AIA Firm of the Year in 1969. Together, their larger buildings brought innovations to the integration of mechanical systems, improving their efficiency and maximizing retrievable space. Their innovating modernist style and developments in urban planning are evident in their use of greenbelts and green design. Projects and buildings include the Brody House in Los Angeles, California, the Walter Annenberg Estate, "Sunnylands," Rancho Mirage, California, and the Campbell Hall School in North Hollywood, California.
