The Joseph D. Oliver House, also known as Copshaholm, sits on 808 W. Washington Street, at the corner of Chapin Street in South Bend, Indiana. The mansion was built for the Oliver family, founders of the Oliver Chilled Plow Works, and named after the Scottish village of the patriarch. It is listed on the National Register of Historic Places.
Built in 1895–96, Copshaholm is a 38-room Romanesque Queen Anne house designed by New York architect Charles Alonzo Rich. The furnishings on all three floors are original, giving visitors a glimpse of how the mansion appeared during the 72 years the Oliver family had occupancy.
