A substantial house lot that included this location was granted to Ipswich founder John Winthrop Jr. in 1633. The east side of the present house was constructed in 1711 by Col. John Wainwright, and the west side was added at the end of the 18th Century, featuring fine Georgian paneling and Rumford fireplaces. The rear ell was constructed during that timeframe but has a massive fireplace, chimney, and summer beam that may date to the late 17th Century when a house on this lot was owned by Nathaniel Treadwell. A reused summer beam in the basement has mortises for tusk tenons, which have been observed only in a couple of houses dating to the mid-1600s. This private home has a preservation agreement with the Ipswich Historical Commission. Read more about the Wainwright-Treadwell house at the Historic Ipswich site.
