The William H. Copeland House is a home located in the Chicago suburb of Oak Park, Illinois, United States.Homes of this style, "classically tinged" and "robust," dotted the landscape of small towns across the United States.[3] In 1909 the then-owner, Dr. William Copeland, a prominent surgeon with offices in Chicago and Cleveland, commissioned Frank Lloyd Wright to remodel the home.[3] In addition to the expansive exterior work Wright remodeled the main rooms on the ground floor to adhere to his Prairie style.It is listed as a contributing property to the Frank Lloyd Wright-Prairie School of Architecture Historic District.
