This organization is focused on trying to solve the housing problem in a way that is certainly more sustainable, but sure to incite. By using shipping containers that are left in ports (it is cheaper to build new ones than to ship them back), they are re purposing the containers to create simple, affordable solutions.

Of course they are running into issues that will ultimately effect how they will present and build their efficient solutions. It seems that there is currently a gap between what the public (or even more importantly City Council) views as acceptable and what the group can currently deliver. It will be interesting to see if design can move the needle on this stalemate.
