I went ahead and purchased a couple of the buildings from eBay. They are fantastic. Here's my first setting of them in place on the module. More photos in my SV Station thread Trees are placed for effect. The road between the buildings will be brick, and there will be a basketball half court at the end of the gold building (with employees playing).
