218 Sleepy Hollow Road

The listing says it's "perhaps the ultimate Mid-Century Modern home available in the world." We can't confirm or deny that statement, but we can assure you that this property, Philip Johnson's Wiley House, is a pretty incredible piece of modern architecture. Located in New Canaan, the same Connecticut town as the architect's world-famous Glass House, the Wiley House is considered the most "livable" of all Johnson's works. It was built in the 1950s, sits on six acres of land, and is "a transparent glass rectangle cantilevered over a stone podium," according to the Wall Street Journal. Wall Street executive Frank Gallipoli bought the property for $1 million in 1994, a time when buying modernist homes was not as popular as it is today. He then spent millions more to restore the property, preserving Johnson's original design, but adding green upgrades like heat-insulating glass panes and floor heating. Gallipoli told the Journal that living in the home is like being "up in a treehouse."
