Description

The Old Mill House is a miller's house dating from the late 18th century or early 19th century. It is constructed of granite rubble, with the front having been rebuilt. The house features a dry slate roof, which has a brick stack at the right end and a lateral stack at the rear left. The building has a double-depth plan and stands two storeys high, presenting a nearly symmetrical three-window front. The windows are 20th-century sashes with glazing bars. The entrance includes an open-pedimented doorway with panelled reveals and an eight-panel door, where the top panels are glazed and there is a squat overlight above. The interior has not been inspected.
