Threshing Mill

This threshing mill is a farm outbuilding built in the late 19th century, with minor alterations made in the 20th century. It is constructed of rubble sandstone with sandstone dressings and quoins, topped with a Westmorland slate roof laid in diminishing courses.

The building has a linear plan that includes an integral wheelhouse and wheelpit. The west elevation features three storeys and five bays, with two window openings on the ground and first floors, and three smaller openings on the first floor, all having flush surrounds. There is a tall taking-in door at the south end of the upper floor. Towards the south end of the ground floor, there is a wide opening below a shallow arch with dressed voussoirs, which is now blocked but was formerly the access to the internal wheelhouse. The north gable has quoined doorways at the north-west corner leading to the ground and first floors, with the first-floor doorway now converted into a window. There is also a small rectangular opening at the gable apex.

Inside, the building retains its internal wheelhouse, complete with a wheelpit and undershot water wheel. It features an upright shaft with a toothed drive wheel and spur wheels to transfer power through horizontal line shafting, some of which remains in place. The timber floors, supported by closely-spaced joists and heavy cross beams, house in situ threshing and chopping machinery, along with a powered hoist mechanism. The roof structure consists of tie beam trusses with diagonally-set ridge purlins and trenched and lapped side purlins.

Overall, this threshing mill is a well-preserved and little-altered example of a late 19th-century powered farm outbuilding, designed to accommodate processing machinery driven by an internal waterwheel, and it retains its wheelhouse, water wheel, power transmission system, and some processing machinery.
