Frick, I was going to post a huge "NO ONE CARES ABOUT YOUR FRIGGEN BOX HOUSE!" But seeing as how you only have the demo, I think it would be a bit unfair at this point.
The build (from a structural standpoint) sucks, but I can't 100% blame it on you.
Buy the game. I built like this when I had the demo, bought it, and this is what I'm building after about 7 month's practice.
