Relay House 6' x 8' x 8' High with window in door in HO scale. Made from precast concrete parts, based on a Permacrete NYC prototype. Two piece kit, cut the vent from the underside of the roof, glue the roof to the walls, glue the vent into the hole in roof, and paint.

Custom relay houses with different dimensions, vent locations and doors can be produced; contact me for info.
