Moved the old out to usher in new housing cluster, sounds familiar!
Gardens would have been grand, private nursing homes like this must cost a bit to run, but then so too did they charge to get the old folk there in the first place..., heck we too will be old and frail "Mills and Boon" no ways!
Awesome visit and reveal!
The gardener must not have liked coming to this place, on his wages he might have been riding a bicycle. A bad ride going back!
Rich are rich by never paying fair earnings, when no longer viable sell land to developers then walk away. Perhaps his speedy escape is the aftermath of what you encountered. 😇
