The Northside House was built in two stages, with the taller section constructed in 1890 by August Anderson and his brother-in-law John Arnquist, and an addition built in 1894 by August and his wife Mary. It was named the Northside House by the New Richmond Preservation Society because it originally stood in an area of New Richmond popularly called "The Northside," where flour and lumber millhands and their families traditionally lived. The house, along with many of its furnishings, was donated to the society in 1998 by Don and Susan McIntyre; Don McIntyre was a grandson of August and Mary Anderson.
