House of the Day: Wide Open Spaces in Westhampton

Commanding 340 feet of waterfront in Westhampton Beach, N.Y., this sprawling mansion is your hedge-fund manager's ultimate seaside getaway.

Priced at $14.995 million (bankers -- the savvy deal-makers that they are -- will probably recognize this number as $15 million), the home is set on 3½ acres (with ample room for a tennis court addition, the listing description notes), and includes seven bedrooms and 11½ bathrooms. Its total space is a whopping 17,652 square feet.
