High Quality Content by WIKIPEDIA articles! The William H. Copeland House is a home located in the Chicago suburb of Oak Park, Illinois, United States. In 1909 the home underwent a remodeling designed by famous American architect Frank Lloyd Wright. The original, Italianate home was built in the 1870s. Dr. William H. Copeland commissioned Wright for the remodel and Wright`s original vision of the project proposed a three-story Prairie house. That version was rejected and the result was the more subdued, less severely Prairie, William H. Copeland House. On the exterior the most significant alteration by Wright was the addition of a low-pitched hip roof. The house has been listed as a contributing property to a U.S. Registered Historic District since 1973.
