Creating shelter for human beings is not a luxury but a primary need. For thousands of years humans have been building villages, towns and cities in some of the most inhospitable places on earth. I have been looking at the benefits that Bushcraft can have on design and how we can construct future emergency survival concepts. The video above is taken from Ray Mears Bushcraft in which he creates a warm living space (snow cave) in the middle of the Arctic. The actual shape of the cave is what struck me as genius.
