Here is a picture of a paper template (I know, I should have glued it on a piece of cardboard, but is is only temporary) of a factory that I am planning to build with Walther's Cornerstone Modulars kits. You can also see a temporary track layout (it still has a lot more work to go!). It will be a backdrop building and will be removable so that I can access the light switch. The track going into the building will be receiving, the one outside will be shipping.
