Wow House: Mammoth Living Space (And That's Just the Pool House)

KATONAH, NY — When you move in, there are just a couple rules of thumb for the new owners of this impressive Katonah estate. First, come up with a name for the homestead that captures the majesty of the 35-acre property (sorry, Falcon Crest, South Fork and Shadow Pond are already taken). Second, always show first time visitors to the pool house. Once they tell you how beautiful your home is, you can then feign surprise and say, "Oh, no, no, this isn't the house," before turning to show your guests the 16,064-square-foot main house.
