House made of scrap
I missed what must have been a great program on the National Geographic Channel. In a World Environment Day challenge, a group of SF architects, building officials and others were challenged to design and blitz-build a single-family house made of scrap.
It was a lovely, Modernist piece. "It risked looking like a bunch of scrap nailed together," says Jensen. "But it ended up being wonderful. It really delighted people. You could see it on their faces when they came through."
Apparently the Scraphouse site still exists: http://www.scraphouse.org/
