It is a rare instance of a First Period house in which its original footprint is still readily discernible, and has not been obscured by subsequent modifications. The only immediately overt exterior indication of the house's great age is the steep pitch of its roof. It is a 2+1⁄2-story wooden house framed with massive oak timbers. It is a "single cell" house, only three asymmetrically placed window bays wide and one room deep, with a chimney on the left side. Its exterior was complete restyled in a 19th-century vernacular style.
