BIG ‘FIGER

Round Hill Road will be less fashionable now that Tommy Hilfiger is putting his stately Greenwich, Conn., mansion on the market.

The fashion mogul, who will be moving to Manhattan when interior work on his Plaza duplex is completed this summer, is asking $27.9 million for the new-construction spec home he bought in 2005 for $18 million before adding sublime personal touches.

Included in the 20,000-square-foot Georgian-style house, on just more than 4 acres, are seven bedrooms, 13 bathrooms, a great room with a 30-foot ceiling, a basketball court, a spa with a waterfall, a theater, a gym and a 2,000-bottle wine cellar. Also included are grand-scale entertaining rooms, an elevator and eight fireplaces.

The gated landscaped property with gardens and manicured lawns, known as “Stonehill,” is surrounded by stone walls and features a pool, poolhouse and tennis court.

Sotheby’s broker Janet Milligan has the listing.

Neighbors include former Citigroup head Sandy Weill, who lives just across the street, and “Judge Judy” Sheindlin, who’s building a major manse a few estates away. Hilfiger previously owned a home in the area that he bought for $5.5 million in 2000 and sold for close to his $8 million asking price weeks before buying his present pad.

He recently sold his East Hampton oceanfront home on Further Lane for $26.5 million. Sources say that Hilfiger is also looking for a smaller place in Greenwich.

Parcel tracking

The Hamptons could see a new record price and price per acre for a “single parcel” property sale. An oceanfront estate with a $65 million asking price has just gone to contract on exclusive Gin Lane in Southampton.

The former residence of Oscar-winning “Chicago” producer Marty Richards and his late wife, Johnson & Johnson heiress Mary Lea Johnson, is on almost 6 lush acres with a 13,200-square-foot main residence, a 7,500-square-foot guesthouse and a four-car garage with staff quarters above.

The grounds feature an oversized seaside pool with spa, a tennis court, a lily pond and gardens.

Inside the renovated manor home are six bedroom suites, a music room, a cypress-wood paneled library and additional staff quarters. The guesthouse includes a den, and three en-suite bedrooms with ocean views.

The buyer is unknown, while the present owner is a “European businessman,” whose name we’ll divulge soon.

If the sale takes place at close to $65 million, it would be about $10.8 million per acre. Meanwhile, the record price in the Hamptons, Ron Baron’s $103 million purchase of the 40-acre DeMenil property in East Hampton (a mere $2.57 million an acre) was in two parcels of $58 million and $45 million.

Posey moseys

Indie movie queen Parker Posey has moved on from her East 10th Street co-op.

According to city transfers, the star of nearly 50 films including “Party Girl” and “Waiting for Guffman” has pocketed $1.3 million for the one-bedroom, one-bath flat on the top floor of a walkup townhouse.

Not bad, considering she was asking only $1.17 million for the place with a fireplace and brick walls. Posey now lives on lower Fifth Avenue where she paid about $1.3 million (must be her lucky number) for a two-bedroom place in a more grown-up building with a doorman and, gasp, an elevator.

Now, that’s ‘the view’

Retired Goldman Sachs manager-cum-bed & breakfast proprietor Robert Mnuchin, and his wife, Adriana, have shelled out $20 million for a full floor co-op at 944 Fifth Ave. Located one floor below Barbara Walters’ place, the four-bedroom, six-bath apartment, with more than 60 feet of park frontage, went on the market last summer for “just” $18.9 million.

The seller is Morgan Stanley director Jay Mantz, who purchased the residence for $16.5 million in 2006 and updated the digs. Included in the apartment are wood-burning fireplaces, an ornate library, a cloak room and a large kitchen and pantry.

The listing broker is Edward Lee Cave.
