A roof, a door, some windows, a floor. All houses have them, but not all houses are alike. Some have wings (airplane homes), some have wheels (Romany vardoes), some float; some are made of straw, some of snow and ice. Some are enormous, some are tiny; some are permanent and some are temporary. But all are home. Take Shelterexplores the ways people live all over the world and beyond--from the Arctic to the Antarctic, from an underground house in Las Vegas to the International Space Station. Everywhere people live, they adapt to their surroundings and create unique environments, using innovative techniques to provide that most basic of needs: shelter.
