Peter Vetsch runs his own architecture office in Dietikon, Switzerland. Since the late 70's, Peter Vetsch has made a name for himself with his earth house architecture. With his technology (sprayed concrete constructions) he manages to create building shells which encompass maximum space volume with a minimum of surface area, an ideal form for energy saving.
Peter Vetsch’s earth houses are based on the interpretation of an environmentally conscious, ecological, and progressive architecture. They stand out due to their closeness to nature and allow an experience beyond the usual four walls and right angles. The earth house concept uses its surroundings as an advantage. The surroundings are not adapted to the building; the house is shaped in order to preserve the natural environment.
The advantages of living in underground homes are many. Earth covered homes are cooler in summer and easier to keep warm in winter. Expensive air-conditioners are not necessary, and green roofs help balance the carbon footprint. Wind, fire and earthquake have almost no impact on the stable round form of the house. There are no vulnerable surfaces that could be ripped away or burned down.
