I decided I needed a building that would justify some traffic and decided to build a factory, loosely based on an old HO FSM kit that I saw on the web.
I drew a quick sketch. and was pretty happy with how it might look.
A mockup gave me an idea of how it might look. I used foam panels that can be quickly and easily cut.
This is a full size model.
The pieces were laid out on 3/8 inch exterior plywood.
I drew in the window and door sizes, as well as the foundation.
After the pieces were cut out, I taped them all together temporarily just to see how they would look, and to make sure that everything would match up.
