Permaculture hurricane rebuilding video?

Hey all,
A year or so ago I saw a video where Geoff Lawton (I think?) went down to Haiti (I think?) and helped with disaster relief after a massive hurricane left thousands of people homeless & without water or sanitation. He built round huts out of plastic bottles and cob, somehow including water cachement. It was an inspiring demonstration of reusing waste in a productive and helpful way.

But I've googled til my eyes bleed and I can't find it anywhere - anyone know where it is, or the title at least? Is it one of Lawton's own videos, but under a title I might not associate with the subject?

My architect dad is very interested and I've spent all evening sharing Lawton's other videos and informing him of other basic permaculture principles.

Thanks all!
