We spend a lot of time looking at shelters here on FastCompany.com --from pop-up shelters  for earthquake relief to the Open Architecture Network's challenge  to build shelters with a social component, there is no shortage of designers trying to solve the ever-present problem of homelessness. But this mobile homeless shelter designed by Paul Elkins and featured on designboom  is--dare we say it--kind of comfortable-looking.
Sure, the 225-pound shelter is tiny and has no room to stand, but that's not the point. It provides everything you need, including a kichen, rest/sleeping area, and makeshift washroom, and it can be easily carted around from street to street. The roof also acts as a raincatcher, and a tank collects water for later use. An overflow feature lets excess water drain to the ground.
At the very least, the mobile homeless shelter beats grocery-cart living--or even, say, renting a studio in Williamsburg, Brooklyn. And we can imagine that the cart could be useful at festivals--i.e. Burning Man--where protection from the elements is critical.
