Polychrome Historic DistrictEdit profile
The Polychrome Historic District is a national historic district in Silver Spring, Montgomery County, Maryland. It recognizes a group of five houses built by John Joseph Earley in 1934 and 1935. Earley used precast concrete panels with brightly-colored aggregate to produce the polychrome effect, with Art Deco details. The two-inch-thick panels were attached to a conventional wood frame. Earley was interested in the use of mass-production techniques to produce small, inexpensive houses, paralleling Frank Lloyd Wright's Usonian house concepts.
