I can't wait to see the spires and the domes

I've no idea how you are managing to get your head wrapped around all those different level dimensions. I'm getting confused just trying to think in American storeys instead of English ones! LOL!

Attic space might have been stuffed full of archived patient records to keep them out of the damp in the basement levels, and out of the way of the active parts of the hospital. Either that or scrupulously empty to prevent fire risks?

Working at a care home, we used to end up with a lot of property left behind by residents and no longer wanted or never picked up by relatives. H&S laws and Infection Control Policies meant that we couldn't give these things to other residents or even sell them, so we had to dispose of them. There were certain things that tended to be saved and used in the lounges after professional cleaning, though, so I imagine there might be quite a hotch potch of ex-personal belongings up there.
