I know that back in the early 70's at Watchtower Farms that the north end of the top floor of the E building was blocked off from everybody entering. There was a brother at a desk in the hallway that would stop you unless you had permission to be there. It was a couple of apartments, one for Knorr only when he came to visit weekly.
If you look at Warwick on google you will notice some houses back down some drives. Hmmm
