An engine servicing facility for the JGL

[eightyeightfan1]

Oh, I also want to model a structure on the roof which would house the top of a flight of stairs from below for access to the roof. It would just have a door, could be made of any # of materials I would guess. Any pics I could work from would be great. Could it be shingled with asbestos type shingles used on homes back then, with tarpaper roof, or would it likely be masonry?

Here's a couple of roof top structures I scratch built for one of my factories. The grey one is the access to the roof, and is simulated to be made of wood with a tar paper roof. The red one is access for maintenance of the elevator equipment. It too, is suppose to be just wood with a tar paper roof. Hopefully these will give you some ideas.
