I have a small lumberyard scene in a corner of my layout, I am building some structures for it and only have room for one now, but I want to expand it in the future. Here is the first building I have, it is rough, but I built it in a couple hours. It is modeled after a lumberyard my uncle used to manage. I need something to model a tattered tarp for a door and a roof, Im not sure what to use for the roof, maybe just more corrugated metal.
