An unfinished house plan based on a design by Frank Lloyd Wright has just been erected in the suburbs of Cleveland. The house is named RiverRock and occupies 2,000 square feet, with three bedrooms and two full baths. The Frank Lloyd Wright Foundation is disputing its claims, though it will acknowledge that Wright originally made the drawings."RiverRock is not Frank Lloyd Wrights workvarying due to codes, materials, and other differences," a representative told Artnet in an email. "Although it is true that the RiverRock drawings were some of Wrights last, the current construction varies from the actual plans designed by Wright. Its a derivative of the original plan."Last month, we covered the listing of Wright's former Plaza Hotel apartment in New York City for $18.9 million.
