The house, possibly the oldest in the state, was designated a National Historic Landmark in 1968.

It is a two-story log structure, sheathed in wooden clapboards, with a side-gable roof pierced by a central chimney.

The walls are constructed out of sawn logs 7.5 inches (19 cm) thick, and dovetailed together at the corners.

The interior is very plain, with wooden floors, paneled walls, and unfinished ceilings.

These types of houses were relatively common in southern Maine during the colonial period, when it was regularly subjected to attack by Native American forces (sometimes with French participation).
