In both layouts, any in-patient rooms have windows.
But in the older building, patient rooms abut each outer wall, and there's a single (too narrow) corridor between them.
A cramped nursing station is squeezed between 2 rooms (in lieu of one) and the rooms hold 2 beds for the most part, but 3-4 beds for those at the ends of the hall.
Those old rooms could barely handle a standard stretcher though the door and had virtually no room for it to line up parallel to a bed.
There was no set of rooms/spaces mid-corridor. Where as that's where most non-patient room space is located in the new build. The new build is actually 2 wide corridors running in a squared-circle.
The new rooms are much more spacious, generally private, and the corridors much wider. The nursing station(s) and the treatment spaces are mostly/all in the interior (non-windowed) space.
