The structures designed by Wright are well documented. Please search our map and state-by-state listings of all known extant buildings designed by Frank Lloyd Wright. If your house is not listed, you may first wish to research locally by contacting your municipality’s building or planning department to determine your house’s architect of record. Most building departments have the original building permits on file, which list the architect of record. Many houses share certain architectural features with Wright designs, such as flat roofs with deep overhangs or heavily emphasized horizontal details, but were not designed by Wright himself. It is possible one of Wright’s many apprentices was the architect of your house, but the Conservancy does not have the resources to determine or confirm the works of Wright’s apprentices.
