The Foster/Bell House is an historic building located in Ottumwa, Iowa, United States. The original house on the property was the home of Judge H.B. Hendershott built in 1862. He sold the property to Thomas D. Foster in the early 1890s. He was the chairman and general manager of the meat packing firm John Morrell & Company from 1893 to 1915. Foster hired architect Ernest Koch to design the present residence. It was originally a frame and stone house in the Neoclassical style that was completed in 1893. The house passed to Foster's daughter Ellen Foster Bell who hired the Des Moines architectural firm of Kraetsch and Kraetsch. They redesigned the exterior to its present Tudor Revival style in 1923. The architectural firm of Tinsley, McBroom & Higgins made significant changes to the interior in 1929. It features Sioux Falls red granite on the main floor.
