I have several of these Ameri-towne building facades that I picked up at shows. I always wondered who built them. The fronts are finished very nicely. My plan is to sandwich them between full Ameri-towne buildings and add an extended styrene or cardstock tarpaper roof to match. If the back was to be visible, I could easily add Ameri-towne back walls as well.
For an end unit, the above suggestions for brick material are excellent. I learned something new here. I didn't know about face brick vs. common brick. The challenge is matching the brick size to make it look right.
