WATERMILL AT NG SE33662005

This is an 18th-century corn mill situated off Tootal Street, originally located off Doncaster Road. The mill is constructed of thin dark red brick with a stone slate roof, and features a timber and metal waterwheel. The building has three main internal bays separated by brick spine walls, and is covered by a six-bay king-post roof. It is a roughly T-shaped structure, with a short, later projection set into the central bay, covered by a lean-to slate roof.

A central cart entry is topped with a segmental arch constructed of brick soldiers. This entry has been partly filled in with later brickwork and contains a doorway. Above is a taking-in doorway with a short platform supported by stone corbels, still retaining its original six-panelled door. A lean-to addition extends to the left. The first bay has a first-floor segmental-arched doorway with a boarded door. To the right of the central taking-in door is a wide segmental-arched window, now lacking glazing. The right-hand bay has a segmental-arched doorway (without a door) providing access to the wheel pit; a boarded door sits above it. It is understood that the mill was originally extended further to the right, but that section has since been reduced. Modern brickwork is visible in the right-hand gable. The rear of the mill faces the River Calder and has four windows to the first floor, with the central one now blocked.

Internally, the central doorway leads into a large room with four spine beams and cross floor joists. A single-flight staircase set against the rear wall leads to the first floor, where metal drive shafts and spoked flywheels are attached to the underside of the tie-beams, along with three timber-boarded grain hoppers. A second staircase leads to the attic. The roof structure consists of evenly spaced oak fish-bone king-post trusses, with principals having chamfered edges and run-out stops. The king-posts fork at the top to house a diamond-set ridge-tree. Each roof pitch is supported by two trenched purlins with chamfered edges, which in turn support original oak rafters from ridge to wall-plate. The northernmost truss is numbered "III" in the centre of the tie-beam and has a modern brick wall built up against it. The roof of the first two bays appears to be a later extension, featuring a softwood fish-bone king-post truss with three tusked purlins to each roof pitch, tenoned and pegged, and softwood rafters of slight scantling.
