There is no record of when the Treadwells acquired this property but stylistic evidence dictates a second period attribution. The original house consisted of a large room with a chimney and entry at the right. Raised field wainscotting in this room is the most exceptional early second period feature. The house was altered in the mid-18th century, and the kitchen and small rear room are finished with trim from this period. In the mid-19th century new stairs and a new chimney were built.
