Spotted on a wet day in Digbeth, just around the corner from the Police station, this factory is in Alsion Street. You can get a good look on Google Streetview.
I know nothing about this place, but it would be a very modelable frontage. There are no awkward curves to deal with for a start. Those concrete window lintels could be set into some brick Plastikard. The windows are a job for scribing clear plastic and wiping paint accross.
One mystery - why is the big slab in the wall unmarked?
I'd have expected something moulded into the surface, but it's blank. Easy to model though.
