It takes four people two hours to put up one of these amazing mobile houses. The walls are made like a garden trellis and spring into shape. The 68 roof beams support a circular opening in the roof to let out smoke. The whole is covered in felt for waterproofing and insulation.
Inside, sitting on the carpets eating our dinner off low tables, we are kept warm by a yak dung fire in a little iron stove. Very snug.
