The house served as a private residence and a tavern during the 18th century, and the snuff mill and water wheel were lost. In 1930, the building was restored to its colonial state by Norman Isham and was opened to the public as a museum in 1931. Many of the house's original wood beams remained intact. It also retained its original four corner fireplaces, one in each room in the house. An English snuff mill built in the early 1730s was transported to the property during the restoration, and it is considered faithful in design to the original snuff mill. In addition, a new water wheel was built and attached to the side of the house, allowing the mill to operate by water power from Mattatuxet Brook. An original colonial-era gristmill was built in 1757 and owned by Benjamin Hammond, fitted with a water wheel. The mill remained inoperable until 2007, when the waterwheel was reconnected to the mill's operating gears.
