The crooked house in Sopot, Poland has an extraordinary and amazing structure. It was built in 2003 with design based on the pictures of Jan Marcin Szancer and Per Dahlberg. It looks as taken from a cartoon movie, its design is “crooked”, but a kind of symmetrically, so it is not ugly at all, just strange! The interesting part is how builders managed to create this genius idea, but the house is a fact and everyone admires their creativity.
Tortoise Earth Home maybe the idea comes from: http://en.wikipedia.org/wiki/World_Turtle "The World Turtle (also referred to as the Cosmic Turtle, the World-bearing Turtle, or the Divine Turtle) is a mytheme of a giant turtle (or tortoise) supporting or containing the world."
