So here's a preview of the next one, the police station. :D
Forgive my terminology- by "Booking area" and "Booking Room" I'm referring to a room where people brought in sit around and wait to be sent on their way or put in a cell or whatever. They seem to be something only bigger cities have, they're seen a lot on some police shows. They'll call people up to a counter and give them a fine or something, detemining if they're going to be held at the station or whatever.
There are no cliche jail fences/doors as far as I know, so I opted for the more modern "door and a concrete room" kind of thing.
Anyway, I tried to keep the outside similar to the existing rabbit hole(as usual). There are actually 4 floors- but one is halved, so that there can be short rooves with a usable, routable floor on top, to keep it looking as close to the rabbit hole as possible. On the roof, at least. :p
