I might have something your interested in. Old factory on the edge of the town i live in, Got bought by a developer, and most of its gone, but there are still 2 or 3 large buildings, at least for now.
Its all VERY
run down and broken.
Not sure about legal access to the interior, you would have to talk to the people who bought it. I'll see if i can find a picture for you
Heres the sign. Used to be a factory for children's furniture
