Doubling Mill Fireproof Mill

Doubling Mill and Fireproof Mill are cotton doubling mills and warehousing that are part of Murray's Mills, which also includes Old Mill, Decker Mill, and New Mill. These buildings were added to the site in 1842. They are constructed of brick with slate roofs, and the internal structure of the Fireproof Mill features cast iron columns and beams in the Doubling Mill. The two mills form an L-shaped block with five storeys. The Fireproof Mill, which faces Bengal Street, has seven bays and an entrance to the yard on the left. The Doubling Mill consists of eight bays, with an internal engine house that occupies two bays to the west of the site, marked by round-arched windows. Each of the other bays contains a small window with a flat arched stone head. There is a circular stair-tower attached to the rear of the Doubling Mill towards the east, and a small ventilation tower that projects from the rear of the Fireproof Mill. These buildings are significant components of Murray's Mills, representing an important example of large-scale mill development from the early 19th century.
