This house in Patagonia was built by Paul Coleman and his wife, Konomi. It features a double wall system that includes pumice from a dormant volcano. Five hundred tons of earth have been moved by hand and everything else that has been used to build the house has come up a very steep 150 meter hill on the backs of the builders and friends. The house has a spectacular view, is very cozy and has a very simple exterior. The earth system keeps the surrounding earth warm and dry in what is an extremely wet and windy environment.
