Description

West Mill Farmhouse is a farmhouse that likely dates from the late 17th century to early 18th century, possibly as a remodelling of an earlier house, with 19th century changes to the windows. An early 17th century datestone is believed to be hidden behind the roughcast exterior, according to the owner. The building is constructed of cob on stone rubble footings, with roughcast on the front elevation and an asbestos slate roof that is gabled at both ends, replacing an earlier thatched roof. There is a left end stack, a rear lateral stack that has been largely rebuilt, and an axial stack.

The layout of the interior is not fully clear as it was only partially inspected during a survey in 1987. It features a single depth range that is four rooms wide, with the main entrance located approximately centrally into a lobby that faces the stair and an adjacent store room. The room to the left of the entrance is heated by a large rear lateral stack, while the extreme left room is likely a 19th century addition. To the right of the entrance, there are two rooms, although it is unclear which one is served by the axial stack; it may be both.

The exterior is two-storeys high with a long asymmetrical front that has six windows. The main entrance features a wide 18th or early 19th century panelled door, with the top panels glazed. There is a second door to the right that leads into the right end room. The farmhouse has a good set of early 19th century casements and sashes with glazing bars.

The interior was only partially inspected, but the room to the left of the main entrance has a boxed-in crossbeam, and the 20th century fireplace may hide earlier jambs and a lintel. Other interesting features are likely to exist elsewhere in the building. The roof timbers are said to have been replaced in the 1920s when the thatch was removed. The farmhouse has group value with the threshing barn located opposite and retains a good set of 19th century windows.
