SPACE top one is Denbigh Hospital. The forked corridor and the mortuary is High Royds. The yellow and black striped "hazard room" is an art installation at Deva Asylum. The forked staircase is St John's Hospital Lincoln. The dentist's room is Cane Hill.
Detroit is the world's biggest ghost city. I wouldn't want to live in Detroit per say, but I love the idea of taking an abandoned house and remodeling it to be inhabited again. I love the stone one 8 pictures down. Just amazing architecture. So sad.
