The Kraus House, also known as the Frank Lloyd Wright House in Ebsworth Park, is a house in Kirkwood, Missouri designed by architectFrank Lloyd Wright. The house was designed and constructed for Russell and Ruth Goetz Kraus, and the initial design was conceived in 1950. Construction continued until at least 1960 and was never formally completed. The owners lived in the house for about 40 years (Ruth died in 1992).
In 1997, the house was recognized with listing on the National Register of Historic Places of the National Park Service. Russell Kraus sold the house in 2001 to a non-profit organization formed for the specific purpose of saving it. Title was subsequently transferred to the St. Louis County Parks Department, which maintains the 10.5-acre (42,000 m2) grounds as Ebsworth Park. The house and park are open to the public by appointment only. Tours are available for a small fee and do not allow pictures to be taken inside the house.
