Water Mill Compound Sells for $17 Million

An approximately 3-acre Water Mill compound with two legal residences — including one that integrates a 19th century farmhouse — recently sold for $17 million.

At 475 Flying Point Road, the hedged and gated property also comes with an oversized three-car garage with a sitting room and a bathroom, plus a 20-by-60-foot gunite pool with spa and a tennis court.

Architect Alexander Antonelli and Fountainhead Construction planned and executed the compound. The four-bedroom main house is 9,600 square feet, and the four-bedroom guest house with solar power and geothermal heating and air conditioning is 5,500 square feet.

“The main residence is accessed from the front entry into the main foyer that incorporates the original 1880s farmhouse, with custom stone and wood floors, library with full bath, living room with fireplace that opens to covered, wraparound outdoor decks, den with fireplace, and formal dining room with fireplace that also opens to the decks,” the listing states.

A main gallery connects the foyer to the modern chef’s kitchen with stone countertops and top-of-the-line stainless steel appliances.

Two stairways rise to the second level with a large landing and coffee bar. The master suite has a private deck, a sitting room, two full bathrooms and dressing areas. Three more guest suites complete the second floor.

The finished lower level includes a gym, media/entertainment space, a full bar, a wine cellar, a bathroom and a sauna.

The barn-style guest house is open-plan with polished concrete floors, powder and laundry rooms, an industrial-designed stainless steel kitchen, a double-height living area that opens onto covered decks, an outdoor shower, and a finished lower level with a media/game room, a full bathroom, a mini-bar and a walk-out egress.

Associate broker Harald Grant and salesperson Bruce Grant of Sotheby’s International Realty had the listing.

“It’s incredibly rare to find over three acres in Water Mill with two legal CO’d residences, a pool, and tennis — all just moments from the beach,” Harald Grant said. “This property is truly one-of-a-kind, and it was a privilege to bring such a special Hamptons offering to market and see it matched with the right buyer.”

The deal closed on July 2, according to Suffolk Vision Inc., which reported the seller was Stefano Corsi and the new owner is See Princess LLC.
