Stone Chateau in Northern N.J. Sells for US$17.7 Million, the State’s Biggest Home Sale in Three Years
The custom megamansion is located in the affluent town of Alpine, not far from New York City.

A Versailles-style chateau in Alpine, New Jersey, has just been sold for US$17.7 million, the state’s highest home sale in the past three years.
The sale of the custom megamansion, which closed Tuesday, is also the highest-priced in the affluent town and in the Rio Vista neighbourhood since January 2022.
David and Mindy Kwon bought the vacant Bergen County land in 2011 for $3.95 million, according to records on Property Shark. They declined to comment on the sale.
The Kwons spent four years building their dream house, which they christened Chateau de la Roche for the boulder that had to be blasted out of the ground before the project could commence.
Designed by Zampolin & Associates Architects, the cast stone, limestone and travertine residence presides over 2 acres.
The interiors are by Denise Albanese, who, in her dual role as realtor associate at the Christie’s Mahwah-Saddle River Sales Gallery, also represented the Kwons in the sale.
“Among the luxury homes in Rio Vista, Chateau de la Roche is the cream of the crop,” she said. “It’s one of the most elegant—there’s a general feeling of grandeur and luxury.”
The seven-bedroom, 10.5-bath house, which was completed in 2017, is palatial enough to suit royalty.
The 25,700-square-foot house, which is about a half hour from Manhattan, has a 15-seat theatre, an elevator, a gas fireplace, a billiards room, two bars, a wine cellar, two indoor plunge pools, a sauna, a steam room, a conservatory and a central-vacuuming system.
Other features include a grand central staircase illuminated by a massive crystal chandelier, a great room warmed by a mammoth fireplace, a conservatory, a mezzanine and an ornately wood-panelled library with a fireplace. The garage can accommodate four vehicles.
Outside, there’s a resort-style swimming pool and a spa.
It’s the details, Albanese said, that set the chateau apart.
“It has soaring ceilings, custom fireplaces and bridal staircases,” she said. “In one of the powder rooms, there is glass-beaded wallpaper.”
Mansion Global could not immediately confirm the identity of the buyer, who was represented by Richard Orlando and Jason Pierce of Prominent Properties Sotheby’s International Realty and Taylor Lucyk of Christie’s International Real Estate Group
Albanese said that the Kwons, who own several other homes, are downsizing.
The transaction, she said, was a “full-circle moment for me as an interior designer and real estate agent. It’s a little sad to see the chateau go, but I’m already working with the sellers on their next interior design and real estate venture.”
Kwon is the corporate vice president and chief legal officer of ADP (Automatic Data Processing), a Roseland, New Jersey., company that provides human resources management software services. And he’s a trustee on the board of SEEDS, a New Jersey-based nonprofit that helps high-achieving students from low-income families.
Chateau de la Roche was originally put up for sale in 2021 for $25 million. Since 2023, the asking price has been $22.49 million.

Designed by the late Kerry Hill and built by Hutchinson Builders, The Residence at Hayman Island blends tropical modernism with absolute waterfront luxury.

Is this Whitsunday’s best home?
Hayman Island may have been ravaged by Cyclone Debbie in 2017, which saw the island, one of the smallest of the major Whitsunday islands, all but shut down, but the 390-hectare paradise has made an extraordinary comeback.
The InterContinental brand took over the island’s only resort, which was completely devastated by the Category 4 cyclone. The same year the cyclone hit, The Residence at Hayman was built, one of just two private residences on the island.
Constructed by Hutchinson Builders, a Tier 1 builder better known for delivering some of South East Queensland’s finest multi-residential developments, the lavish home is made from reinforced concrete with a blend of glass and timber battening.
It was designed by the late, internationally renowned architect Kerry Hill, widely regarded as a key figure in refining tropical modernist architecture. Hill was an island specialist, having designed several major resorts in Bali.
The Residence at Hayman spans three levels and offers over 1,400 sqm of living space, including around 580 sqm of internal living areas. The remainder comprises breezeways, terraces, and balconies designed to embrace the island’s subtropical climate.
Entry to the home is via the upper level, as the property tiers down the site with direct access to the beach. The top and lower levels accommodate most of the home’s eight bedrooms, as well as a study and a double garage with buggy parking, the preferred mode of transport throughout the Whitsundays.
The middle level is home to the main kitchen, living, and dining areas, complete with a full butler’s pantry. It opens to a large, L-shaped terrace featuring an outdoor kitchen, alfresco dining and lounge zones, and a sundeck. The terrace flows to the basalt-clad infinity swimming pool, deck, and cabana with integrated seating, as well as a pool house.
Owners or guests of The Residence also have access to the InterContinental Hayman Island Resort facilities, including 24-hour room service, butler assistance, private chefs, and the resort’s wellness centre.
Whitefox agents Cheyne Fox and Nic Whitehead are marketing The Residence as “a rare and extraordinary find.”
“This is more than just a home, it’s an opportunity to own a piece of paradise, a legacy to share with family and friends for generations to come,” Fox said.
The only other private residence on Hayman Island, Hayman House, is also on the market. Commissioned by Terry Peabody, former billionaire and Transpacific Industries founder, Hayman House was first listed last year with hopes of $27 million, later reportedly reduced to $20 million in early 2025.
Designed by Kerry Hill and also built by Hutchies (in 2010), Hayman House shares a similar design ethos to The Residence, albeit on a smaller scale. Its 18-week construction endured three cyclones, with all site access via the beach, which had to be reinforced to prevent heavy vehicles from sinking into the sand.
