Background: Artist and architect Robert Bruno has been at work on his steel home since 1974. Bruno has said that he wants the shape of the structure to be somewhere between animal and machine. Why Its Unique: Most homes have an initial skeleton that is built upon throughout the construction process, but Bruno has approached this home like a sculpture, building it on the fly and making constant modifications. Koliopoulos points out that the four legs and cantilevered design minimize the structures impact by not disrupting the earth as much as a typical home design would have. Estimated weight of the structure is 110 tons.
