If you have the cash and the pessimistic attitude of impending doom, then take a look a this 4,200-square-foot home in Yellow Jacket, Colo. The facade leaves much to be desired, but apocalypse-proof structure offers all the amenities to be self-sufficient for a long time. For only $11.5 million, this home includes "nuclear rated" reinforced concrete and steel walls, a 100-foot radio tower, a helicopter pad on grounds, a seven-stage water filtration setup, and four separate power systems, including a solar array and a wind turbine, as well as propane and gas generators as a last resort.
