Union Mills

Union Mills is a room and power weaving mill built in 1867, with extensions in 1871, an addition in 1927, and minor alterations in the late 20th century. It was constructed for the Skipton Land & Building Company and designed by J. Nelson of Nelson and Burnley. The building features dressed stone with ashlar dressings, and roofs made of Welsh slate and glass.

To the north, there are original weaving sheds and a warehouse, while the engine house, boiler house, and chimney are located at the southeast corner. Additional weaving sheds and a warehouse were added to the south later on. The front facing Union Terrace has single-storey weaving sheds on the right, which include a 20th-century entrance and eight small round-headed openings above. On the left, the warehouse has central double door openings with original overlights, flanked by single original windows on both lower floors, with a central 20th-century window replacing an original door.

The east front, facing the canal, features a three-storey warehouse with thirteen windows and a projecting 20th-century brick office addition. The warehouse retains many original 42-pane windows on the ground and first floors, while the top floor has nine-pane windows. The central engine house has a tall round-headed window with a garage door below, a balcony, and glazed doors. To the left is a gabled lower boiler house with large access doors, followed by a later and taller gabled boiler house with large windows. There are also single-storey weaving sheds with eight flat-headed openings. Beyond the warehouse are three windows, with the left one converted to double doors and an overlight, the central one featuring original 42-pane glazing, and the right one having six-pane windows. Above, there are three more original 42-pane windows and two 20th-century windows in the gable.

The south front has two storeys with eighteen windows, mostly original 42-pane windows with wooden frames, and an archway at the west end. The west front consists of single-storey weaving sheds with some 20th-century alterations. The interior of the weaving sheds is supported by cast iron columns designed to accommodate belt-driven power, and the warehouses also feature similar columns and wooden floors.
