 In the mid-19th century the property passed to John Anderson, a noted Maine politician who transformed the property into a summer estate and gentleman's farm.Anderson retained Portland architect Charles A. Alexander to make the Gothic Revival alterations to the house, and it is assumed Alexander also developed the plans for the other surviving buildings.John Anderson's son, John Farwell Anderson, is notable for introducing Devon cattle into the state on this farm, and making it one of Windham's most successful farms in the 1860s.
