2 Pauls Lane — Water Mill, N.Y.
Plenty of green architecture these days is contemporary, angular, and ready for the glossy pages of design magazines. But this traditional Hamptons-style shingle home near Easthampton, N.Y., looks as if it has graced the lot for decades.
The home is over 9,000 square feet designed by Robert Schwagerl, husband of the realtor selling it. The seven-bed, nine-bath home, on one acre, has all the normal bells and whistles—chef’s kitchen, pool house, roof deck—tied up in an locally sourced, energy-efficient, air-purified package. Asking price: $7.85 million
