From Wikipedia Link -- "Carleton Mill dates back to 1861 when it was originally built for spinning cotton, the mill later housed a mail-order business throughout the 1930s. During the second world war the company Rover worked at the building to produce aircraft parts. Shortly after, the mill returned to its original use as a textile factory and later would produce carpets, eventually closing down in November 1999. It was recently converted into apartments."
