Bobby's house is located in a scrap yard that Bobby owns. The main rooms that appear on the show are the kitchen, Library, and closets. There is also staircases that lead up and down stairs. In the library it is filed with every kind of lore book, and rituals. Near the corner of the room is a fireplace, with a Devil's Trap on the roof. The room also has a desk for Bobby to work at. In the kitchen, it has basic kitchen stuff, plus a bunch of phones Bobby uses to pretend to be CIA, FBI, etc. The closets pimps it out to have a trap lever.Upstairs isn't seen very much. All there is known about the upstairs is that it holds the bedrooms and closets. Downstairs Bobby has a panic room.
