If you feel like moving to the Hamptons, The Sandcastle can be yours for $40M. The entire house is beautiful and luxurious, but when you're not sunning on the beach you may find yourself spending most of your time in the basement. It features a full bowling alley, a rock climbing wall, a halfpipe, a performing arts theater, a spa and a convertible basketball/squash court.
