A hybrid earthbag and pallet building would provide excellent protection from the weather and would be virtually free to build with debris and discarded shipping pallets. The addition of rain water collection, humanure composting, and simple solar oven(s) would provide fresh water and help keep human waste safely out of the way. Any additional materials would only enhance this basic earthquake resistant structure.
Be sure to visit Michael Janzen’s Tiny House Design website for many more sustainable building ideas.
