Sanford House (Sioux City, Iowa)
The Sanford House, also known as the Stone House or Summit Mansion, is a historic home at 1925 Summit Street in Sioux City, Iowa. It was built in 1914 for Lucia Stone in memory of her husband, Edgar Stone, by Swedish immigrant builder Andrew Ostling, at a cost of $34,500.
The two-story neocolonial house (Colonial Revival with Prairie influence) has about 6,816 square feet of living space, including 2,170 square feet on the first floor, 1,908 on the second, plus a finished basement and a semi-finished attic. It features 4 bedrooms, 5 bathrooms, 2 fireplaces, and a sunroom added in the 1980s. The north wing housed servants’ quarters, connected to the main rooms by a bell-pull system; a coal bunker in the basement was later turned into an office.
Lucia Stone died in 1922, and Edgar had died in 1911. In 1936, the Sanford family — Arthur Sanford and his wife Stella — bought the house. Arthur became famous as Sioux City’s greatest builder, shaping many local landmarks and hosting John F. Kennedy at the Sanford House in 1960. The Sanfords owned the home for about 60 years and were noted for their philanthropy in Sioux City.
In 1994, John T. Marriott II and his wife Rebecca purchased the house and undertook a five-year restoration to return it to its neocolonial roots. The coal bunker was turned into an office, and the basement was refinished; the period look led contractors to call it “Marriott Manor” during renovations.
The Mariotts sold the Sanford House to John and Kathy Pritchard in 1999. The house was added to the National Register of Historic Places on March 21, 2003 (NRHP reference number 03000359) for its historical significance and its connection to prominent Sioux City figures. In the 1990s, it was sometimes nicknamed the “Home Alone house” because it resembled the famous movie home.
