They're at 31. The house is 41 which was Lan Constructions Group Ltd - Building Construction Contractors at some time (according to 192.com) And there are too many panels of sockets for the number of beds you could get in a room. I think any sort of medical or commercial facility would have used bedhead/dado trunking. Somebody went to a lot of time to put in all those flush sockets.
This shows it furnished and for rent (which would also match the non-upkeep of the garden)
