This reminds me of the hospital where my kids were born. It needed to grow in a crowded college campus area, and so it absorbed adjacent buildings into itself in one giant katamari. So you often do see ramps going up or down in the middle of a hallway because the floors didn’t quite line up, as well as the occasional brick wall or windows of what used to be an exterior wall in the middle of the building.
