It would be nice if the kit came with a exploded view of the basic building. The instruction are not that good. The kit has some parts that you don't use and other parts shown in picture of building are missing. Once you figure out the best way to build it with what you do have in the kit it's OK and it fits with S scale 1:64 HO Slot cars & track setup. It will work just right with my HO Slot car setup as a blue & white warehouse building with three open doors to park trucks & cars.
