Trencherfield Mill

A cotton spinning mill, later used as a textile workshop, warehouse, museum, and offices, was built between 1907 and 1908 by Potts, Son and Hennings for William Woods & Son Ltd. It was subsequently altered. The mill is constructed with an iron and steel frame, clad in red brick laid in an English garden wall bond, with terracotta dressings in a buff colour. The roof material is concealed but is likely asphalt.

The main range is very large, featuring approximately 15 bays with two windows per bay. The exterior displays brick pilasters, while the top floor has a sill band and terracotta enrichment to the pilasters. There are three-light windows with blocked colonnette mullions and parapet upstands. A rectangular corner tower rises from the main range, with various windows including keyed oculi. The tower features a three-stage turret with a cornice to the first stage, terracotta panels to the second stage lettered "1907" with open pediments above, a banded square top stage with a three-light window on each side and a steep pyramidal roof. An engine house, three storeys high and eight windows wide, is attached at right angles near the south end of the east side. It has round-headed windows at the first floor level and oculi at the second floor level, all keyed. A large lunette with three similar oculi sits above the round-headed windows, and the engine house has a hipped roof. A boiler house is situated in the south angle of the engine house. A 20th-century tourist shop is attached to the north side of the main range.

The mill’s interior retains the original 1906 four-cylinder triple-expansion tandem steam engine, manufactured by J & E Woods of Bolton, which is in working order.
