Description

Kimpton Mill and the adjoining barns are a former watermill that has been converted into a house. The watermill dates from the late 18th century and is located near the road. The northern part features a 17th-century timber frame mill-house, which was recased in the late 18th century and has an early 19th-century rear extension. There is also a northern extension added around 1980. The building has two storeys, with a red brick ground floor and a 20th-century weatherboarded upper floor. It includes three 19th-century casement windows. The mill-house has a tall red brick chimney stack with four joined square shafts and mid-19th-century casements. Inside, there is a lobby entrance on the east side with a 17th-century door and staircase. The adjoining barns to the north create an open courtyard and date from the late 18th to early 19th century. They are single storey, constructed of chequered and plain red brick. The northern barn features four square slatted ventilators, while the eastern barn is timber framed and weatherboarded, consisting of four bays, all topped with plain tile roofs.
