Unity Temple

North Elevation of Unity Temple, Oak Park, Illinois

Oak Park, Illinois · Architect: Frank Lloyd Wright · Built 1907

Frank Lloyd Wright's design for Unity Church was conceived with the prime objective of giving exterior expression to a room of worship by subordinating the smaller auxiliary functions to the main room. It is one of the earliest experiments in the use of reinforced concrete in the United States, with the pebble aggregate exposed on the surface for texture.

  • The building permit gave the cost as $33,000, but Wright named the sum $45,000, per HABS data pages
  • Materials: reinforced concrete, with pebble aggregate exposed on the surface for texture, per HABS data pages
