This 3,500-square-foot Wainscott spread listed for $21.5 million, owned by J. Crew chief executive Mickey Drexler, comes with its own boardwalk that leads you through the dunes to a private beach.

The three-bedroom, 2.5-bath home on 2.3 acres includes 315 feet of ocean frontage and views over nearby Wainscott Pond.

Refurbished about five years ago by architect and designer Thierry W. Despont, the house is a blend of traditional and modern elements with an open floor plan, double-height ceilings and large picture windows, says listing agent Ed Petrie, of Compass Realty, who is co-listing with James Petrie and Julie Wolfe.

“From any window, the views are spectacular,” Petrie says.

Each of the three bedrooms has direct access to the outdoors.

“It’s an ‘upside-down’ house — the bedrooms are downstairs and the living areas are upstairs,” Petrie says. “Because it’s built that way, you can just walk out from each bedroom.”

An eat-in chef’s kitchen overlooks Wainscott Pond, and there is also a den-library and media room. Wide wraparound decks and the beach boardwalk offer ample opportunities for outdoor dining.
