어스 하우스(earth house)

Earth houses located in Dietikon, Switzerland. designed by Peter Vetsch and are based on the interpretation of an environmentally conscious, ecological and progressive architecture.
The earth-house concept uses the ground as an insulating blanket that efficiently protects it from rain,
low temperatures, wind and natural abrasion.
An earth house does not have to be built under the ground, it can be placed onto naturally grown terrain.
