This beautiful, 4,000 square foot LA home was built from the waste materials of a 747 airplane. To build most of the home architect David Hertz utilized 4.5 million raw materials from scraps that what would normally have gone into the garbage. The main residence uses the wings and tail section of the plane for the roof. There’s also an art studio, guest house, and animal barn all made from the fuselage. A meditation pavilion was also created from the cockpit. Not a bad use of scrap metal.
