Proctors Works With Attached Chimney

Proctors' Works, formerly known as Cow Lane Cotton Factory, is a cotton spinning mill that later became an ironworks. It was built between 1827 and 1844, with an engine house and chimney added between 1844 and 1851. Late 19th-century additions include offices and a large crosswing, which was once a roller skating rink with a provision store in the basement. At the time of the survey in 1991, the building was mostly unoccupied. The structure is made of coursed squared sandstone and has slate roofs.

The main part of the building is a rectangular spinning block located on the west bank of the River Calder, with a rectangular engine house nearby, now connected by infilling, and a chimney situated close to the west side. The spinning block features four storeys and eight window ranges, with the west front largely obscured by later additions. The rear side, which faces the river, has vertical rectangular windows with raised sills and plain lintels, including a tall round-headed window near the north end, all of which are now blocked with brick. The building has gable copings with kneelers.

A full-height one-window link made of random rubble connects the spinning block to the four-storey, two-window boiler house. The boiler house has similar windows on its rear wall but features the remains of a semicircular arch at ground floor level and three loading doorways above. The chimney, located approximately 0.5 meters from the front of the boiler house, is circular and has 20 metal straps, resting on a massive square plinth.

Inside the spinning block, wooden floors are supported by wooden beams and a single row of cast-iron columns in the center of each floor. The engine house has been remodeled with iron beams for the floors, while the former skating rink includes a spectators' gallery around a well.
