I'm using mine as an old Firehouse which has been purchased by the "Occult Research Center" for their HQ.
Other side of the building. As you can see the side door is hinged to open and close. I cut out the windows on the door, and applied some more of the silver puff paint for the doorknob. The sign is another from a model RR site.
View of the 1st/ground floor interior toward the front of the building. The firepole goes up all the way to the to top floor.
