Here's my take scratch building the "Red Rocks Railroad" mine building.,I've yet to do the 1st story area,(the lower area ),but the upper area is pretty much done accept for roofing the back sides,and the stain and weatherization overall.Its footprint will be about 8"x22" at its widest points.
I went with shake roofing on the wing sections,and metal on the taller middle section.(my railroad is depicting the southwest area coastal mtns. of Washington state),south is the Columbia river,west is the Pacific ocean, thus our railroad name will be the "Columbia Pacific" railroad.
