Space House (Chattanooga, Tennessee)
When this three-level flying saucer-shaped residence was built in 1970, it became known as the “house of the 21st century.” Futuristic features such as an entrance staircase that retracts with the push of a button and support legs that provide plumbing and electrical connections make this house just as interesting on the outside as the inside. This rare piece of architecture recently sold for $135,000—quite the bargain for a ride into the future.
