At the time, the town of Rye was part of Connecticut. He traded houses with Timothy Knapp of Stamford, CT, who then built the foundations of the current structure as a two-room residence between 1667 and 1670. Knapp was the deputy to the General Court in Hartford, Connecticut, as a Town Constable and Tax Collector. He was also a vestryman of the Grace Episcopalian Church.Ezekiel Halsted, a wealthy landowner originally from Long Island, purchased the property from Timothy Knapp’s sons in 1746. He expanded the house, adding a second floor using "post-and-beam" construction with a sloping roof in the back containing a dining room and kitchen, which gave the house the distinctive saltbox architecture. Beams are hand-hewn, and some retain their original bark. The house has cellar walls reinforced with lime made from crushed oyster shells, 12-inch wooden nails holding floorboards together and a massive center chimney reinforced with mud mortar. The Halsted family lived in the house for the next 157 years.
