  • You'll never be alone at this "true modern marvel." Whether they're peeping through your windows or walking through your door, guests of all sorts will always be at hand.

    The $13.9 million house, according to the Sotheby's listing, "comes with an open door policy," whether you like it or not. The windows are so enormous they aren't even called windows but "picture glass walls," which "slide open to welcome the fresh sea air." Get used to being hospitable, because in the absence of real walls the house "dissolves the boundaries between interior and exterior." Nature will always be a part of your indoor routine, even if that means it's flying beak-first into glass.

    Considering that the house is a "modern masterpiece," it's incredible that it's managed to disappear so completely into its surroundings. Then again, when your exterior space is an "interior landscaped courtyard," dissolving that boundary might not be so difficult. The property blends quite smoothly into the Hamptons' manicured wilds. — William Alden
