A quick look at the Google Maps aerial below reveals a quite different, sprawling campus, thanks to a series of additions. Several parking areas have been enlarged as well.
Here's an architectural rendering of the hospital circa 1970, courtesy of the Alamy stock photo website.
There are some oddities if you compare all three images. Perhaps some of the buildings in the architectural rendering were merely proposed, as they are not visible (at least to my eye) in the current aerial.
