Historic England is reporting that there are some 600 disused mills in towns and cities across the North. Many of them are in or near to the town centres and are already connected to all services and transport links. A lot of them are Grade listed so cannot be knocked down, but they could be sympathetically transformed. It is estimated that they could be converted to provided something like 120.000 homes.
I took a part-time job as a courier when I was at Uni. One of my regular drops was an old water mill in Kirkstall that had been converted to a suite of design studios. When the business there grew and moved on it was converted into 22 apartments and because it was an ex industrial site the old outbuildings were cleared to create plenty of secure off road parking and communal gardens.
