The Vernon Mill at Portwood, Stockport was designed by architects Joseph Stott and Son with the foundation stone laid on 31 October 1881. Built for the Vernon Cotton Spinning Co., Stockport, Limited, it was the first limited liability cotton mill to open in Stockport. In 1891 there were 150,000 spindles, 458/558 weft,. 308/428 twist.

The Bank of England set up the Lancashire Cotton Corporation in 1929 to attempt to rationalise and save the industry. Vernon Mill was one of 104 mills bought by the LCC, and continued in that ownership until 1964 when it passed to Courtaulds. It is now listed Grade II and is occupied by multiple businesses including a gym, a boxing gym, and various art studios. It was purchased by ZS Properties (Mcr) Ltd in October 2018.
