text: I've tidied up the outline of Northumberland a bit, using Esri aerial photo. Main building outline needs a big tidy up and York is missing. I think Stag's Head, Dining Room, etc, should be points within the main building, rather than buildings in their own right. 
  
  Unsure about the best way to record blocks within the wings. Cumbria Wing has been mapped as five separate buildings, but I'm not 100% that's the best way to do it. 
  
  Some info on indoor mapping is here (but doesn't cover how to do blocks): https://wiki.openstreetmap.org/wiki/Simple_Indoor_Tagging
