Wash Pit Mill

Wash Pit Mill is a textile mill built around 1840. It features hammer-dressed stone and a stone slate roof, standing 4 and a half storeys tall. The building has a gable front with five bays and seven bays on the returns. All windows are fitted with thin ashlar flush sills and lintels, and have six-paned timber glazing with top casements. The gable is coped with kneelers, and the west gable includes a chimney. An arched window is located in the gable apex, and the outer bay windows of the attic storey have lintels aligned with the roof pitch, which is an unusual feature. There is a taking-in door in the five-bay section that serves the first three floors only, and custom glazed rooflights are set close to the ridge, with three on each side.

Inside, the mill has timber flooring supported by joists and spine beams, which are held up by cast iron columns with ring caps. A stone cantilevered semi-spiral stair rises to the attic on the north side, illuminated by a small lunette at the attic level. The roof structure consists of a seven-bay softwood fish-bone king-post design with a tie-beam at collar level. The principal rafters support five purlins on each side and are morticed into the main spine beam, which acts as a lower tie-beam and supports the attic floor. Unusual tumbled wedges, built off the floor at the eaves edge, support vertical posts to the principal rafters with notched joints, and these wedges are bolted through to the spine-beam/tie-beam.
