We have built a rocket-ship, full three stage thing that came in five pieces, but mostly the stuff we build is all open at the top. No roofs, just over-hangs/awnings and hanging ceilings (we build it on the ground and the riggers suspend it).
Just as we are not really builders, I'm convinced the designers are not real engineers.
