Scrap house video

Great video about building a house completely out of scrap and trash. We usually steer clear of these produced "reality" shows, but this one at least shows what can be done with a little ingenuity and a lot of scrap. It's unlikely that just an average Joe could go into a scrap yard and walk away with twenty thousand bucks worth of steel, but who knows, anything is possible when people just don't have the space.

QUESTION: When educational shows skip over the most important processes and just show the finished product, does it do more harm than good? When somebody actually tries to do this and they are hit with cost and fees that were not even mentioned in the “how to” video, does this discourage real implementation? Does it just amount to entertainment?
