The modern caveman can still live underground. And I can insure you in 2011 being a caveman is no punishment :-). The so called earth structure houses provide organic forms, their development requiring creativity and a strong sense of space and this one is designed by Peter Vetsch, are based on the interpretation of an environmentally conscious, ecological and progressive architecture. The earth- covered houses are grouped centered around a small artificial lake with the entrance well hidden and integrated at the side of the settlement.
