Boiler House And Engine House And Rope Race And Water Tower And Powerhouse At Westwood Mills

The Boiler House, Engine House, Rope Race, Water Tower, and Powerhouse at Westwood Mills were built in 1826, with mid and late 19th-century additions, for the Shaw and Cotton families. The structures are made of coursed and squared local gritstone, although the stone slate roofs have largely been removed.

The Powerhouse is a three-storey building with a four by three bay layout, attached to the south end of the West Block. It features north-facing doors that provide access to the old mill yard, large windows with segmental heads and three by three pane frames, stone gutter brackets, and kneelers. The roof has three parallel ridges, and there is a two-storey building on the west side with a lean-to roof, where the west wall is angled to allow access between it and the mill dam.

Inside, the ground floor has cast iron columns that support brick arches. The Water Tower and Rope Race block run along the entire length of the south side of the Powerhouse. The Engine and Boiler Houses are attached to the southwest corner of the Water Tower. The gables of the Engine House feature tall windows, with a round arch on the east end, which includes an inserted doorway and external steps. The Boiler House has a wide entrance door on the ground floor and a three-light Venetian window in the west end.
