On creation of 8x8 foot with 7 foot to 5 foot sloping roof as temporary sleeping replacements for flimsy tents, built from waferboard 5/8 nominal and 2x4x8 foot studs, minimal requirement and before any roofing material it's under $300 in supplies. #30 felt is fairly cheap to cover corners against drafts if needed and provide roof area rain and snow protection. Rigid foam board 4x8 foot 1 inch thick is $14 and 10 of those will insulate the walls and ceiling to add comfort and heat retention in winter, so another $140 for the added comfort. All total, some nice homeless detached shelters just for sleeping in maybe have a thrift store couch and chair in for $500 per occupant, or couple is possible. Public bathroom facilities or port-a-potties placed nearby can be used.
8 foot square room is considerably more protected space than most homeless get today under the overpasses, elevated areas where so many congregate in Obamaville's.
Hmm, maybe they should walk around with briefcases with clock guts and wires stuck inside them, might get more attention from Obama. If you want welfare in America today, you should be female, black, and several illegitimate children, and for better medical have another bun in the oven too.
