If there's no space in a shelter--or the shelter isn't safe--then the homeless need quick, portable, and durable housing alternatives. Professional architects have used their skills to develop solutions that are reachable by homeless people around the world, such as the WheelLY--an emergency housing concept by the Italian design firm ZO_loft. It consists of an aluminum frame and 2 polyester resin tents.
When not in use, the owner can fold up and roll the WheelLY around.
This is 1 of 20 housing designs made specifically for the homeless. You can read the rest at When on Earth.
