neat house design

This is incredible, and familiar. Where I come from, there are shantytowns where its citizenry have been living 'green for generations. Admittedly this young man's 'shanty' or 'chengguan' is markedly more aesthetically pleasing than the shanties I grew up seeing, but the economic incentive to build it is the same.

Where I come from, shanties are built out of the detritus of living. In my youth I often saw folks taking old cans -- like a soup can -- and unfurling the curl until what is left is a rectangular piece of tin, akin to the shape of a shingle. After collecting the cans and unfurling them, they were collated for size and thickness and then nailed on to a basic wooden frame. What you are left with is a metal hut... A little more ingenuity would have the new homeowner rigging electricity from some main switch and voila! the result is a home.
