Or possibly a caravan-park-to-be. This is the old Police stables and kennels, and dog-training ground, I think. There are plans afoot for the Baltic Wharf caravan park, forced out of its home by the plan to redevelop the area as flats (which I imagine will be touted as "affordable" and then turn out to be luxury apartments with at most 5% barely-"affordable" apartments around the back), to this site.
