Switzerland-based architect Peter Vetsch’s Earth Houses. Earth House Estate Lättenstrasse is located in Dietikon, Switzerland. The viridescent mounds of earth have the homes tucked in beneath them, keeping them almost hidden. It’s like stumbling upon a secret underground society that has balanced the best of modern design and energy-efficient living. They appear like cozy huts to live in but are actually quite spacious inside. The estate includes 9 separate homes, featuring three 3 bedroom, a 4 bedroom, a 5 bedroom, three 6 bedroom and a 7 bedroom house. There is even an artificial lake in the center, a subterranean parking lot, and room to grow vegetation on the property.
