There was a notice of seeking possession on the gate when I got around to the far side. Looks like it's definitely going to be the replacement for the caravan park at Baltic Wharf. Shame for the caravan folk, really; this is sandwiched between major roads and not anything like as close to the pubs and other tourist-friendly places around the harbourside.
