Harrison House is a two by two house, with two rooms downstairs and two upstairs. The ground floor of the house contains the Parlor to the left (west) and the Hall to the right (east). The Parlor has a distinctive corner cupboard made of pine and decorated with carved rosettes. The Hall was a versatile space, used for eating, working, and gathering. For example, a woman living in the house would have come to the Hall to cook, make candles and soap, weave, spin, and sew. Sleeping quarters were upstairs. The Branford Historical Society uses the Hall Chamber (2nd floor, east side) to display exhibits and artifacts relating to Branford history.
