Evidence: The house originally had a central hall with two rooms on either side. In 1840, a rear addition was built, adding four main rooms and a shed-roofed patio. Original wood fireplace mantels are present in the original four rooms, though they have been sealed with marble hearths. A sunroom was added to the west of the house in the 1940s, and is accessed through an arched entry in the front left room. A kitchen was originally attached to the rear of the house via a breezeway, but was moved and repurposed as a horse barn.
