Property Details


Standing majestically on well over 5 magnificent acres on what was once part of the du Pont estate, this enchanting young stone and stucco, 8-bedroom, 11-full bath, 4-half-bath, French chateau is truly an architectural masterpiece. Combining the grace and charm of “Old World” design with all the luxury and high-tech amenities so sought after today, it provides the ultimate venue for opulent “Gold Coast” living. Approached through iron gates off a quiet cul-de-sac road, populated by equally grand estates, a long winding drive leads to a circular courtyard. One can’t help but notice the graceful slate roof wrapping around various towers and turrets and the imposing front portico with massive hand-carved entry doors. An arched porte-cochere leads through a wing of the manse to a large service courtyard and attached 4-car garage. No expense has been spared in creating this magnificent residence, from its Brazilian cherry floors and hand-carved mahogany doors to its “Smart House” technology allowing effortless control of security, telephones, intercom, sound system, water filtration and more. Every room has been impeccably designed to create an inviting and comfortable space with exquisite ceiling, wall and window treatments. LOCATION Originally purchased in the 1600’s from the Matinecock Indians by early settlers, the Cedar Swamp territory east of Hempstead Harbor became a farming community of mostly English and Dutch corn farmers whose descendants sold their produce to a corn starch factory in nearby Glen Cove. By the turn of the Twentieth Century, many magnates and financiers were drawn to the area to build their grand estates. Today, the gentle rolling and wooded hillsides of Brookville are dotted with beautiful properties. According to Bloomberg News, Brookville is, the wealthiest community in the nation. Their residents enjoy a great location convenient to boating, golf, equestrian facilities, quaint village shopping, museums, the award winning Jericho School District, and the Long Island Railroad putting them within a comfortable 30-mile commute to Manhattan. DuPont Estates is a gated enclave of 7 properties encompassing approximately 53 acres that were, at one time, part of the Alfred I. DuPont 101-acre estate. Built in 1917, his mansion, “White Eagle” and the entire estate was sold in 1971 to New York Institute of Technology, which has its Old Westbury campus next door to the property. The institute kept the mansion and surrounding property for its use but sold the remaining acres, which are now DuPont Estates in the early 21st Century. Paying homage to the original estate, these new grand mansions and their secluded and gated properties are the epitomes of grand and gracious North Shore living. PROPERTY Acres of sweeping emerald lawns edged by gorgeous raised beds of flowering shrubs and trees give a sense of endless domain to this breathtaking property. Ideal for summer entertaining on a grand scale, the estate includes an almost hidden tennis court backed by pristine woodland and a fabulous entertainment complex. Its expansive granite terrace connects a freeform heated Gunite pool, spa, and waterfalls with a romantic pavilion with attached cabana and bath, and flanked by a circular outdoor kitchen with refrigerator and sink and by a courtyard with built-in grill and fireplace. A short walk away, a meditation hut and a koi pond provide a spot for quiet reflection. Extending across the rear of the house, a spacious bluestone patio provides easy access from the principal rooms to the outdoors, ideal for al fresco dining and relaxing. At one end, a patio off the living room enjoys views of a nearby reflection pool, and at the other, a sunken terrace with fireplace provides access to the lower level’s entertainment rooms and pub. Offering ample space for service vehicles or valet guest parking, a large courtyard is accessed from the front courtyard through a porte-cochere that separates the stalls of the attached 4-car garage. Estate fencing, electronic gates plus extensive outdoor lighting and security systems are practical additions. RESIDENCE Sunlight, entering through a 2-story wall of windows, dances across the radiant heated, inlaid crème marble floors in the ethereal entrance foyer. Here is featured a custom floor medallion echoing the design of a domed ceiling above an Italian crystal chandelier. A graceful floating staircase with filigree balustrade is accented by sconce-lit fielded paneling. Adjoining this area are an elevator, cloak room, powder room and gallery accessing the living and dining rooms and an inviting library with fireplace and French doors opening to the rear terrace. Also opening to the terrace and to its own separate patio, the striking and spacious living room features harlequin designed wall coverings, an impressive marble fireplace, gleaming inlaid floors and massive crown moldings. Eighteen-karat gold adorning the ceiling and fielded panels helps to create a stunning venue for elegant repasts in the formal dining room, which enjoys a panoramic view of the rear property through a huge bay window. Connected to the dining room through a butler’s pantry, the spectacular gourmet kitchen is a chef’s dream. Marble-topped custom cabinetry continues the harlequin theme. A center island boasts a farm sink, 2 butcher blocks and seating area. High-end appliances include separate SubZero refrigerator and freezer, huge Wolf professional gas stove with 6 burners, grill and 2 ovens, 3 Bosch dishwashers, and a microwave. Radiant-heated stone floors extend into the charming turret breakfast room with raised fireplace, teacup ceiling, and windows overlooking the pool area. A peninsula with seating overlooks the family room. This quaint and cozy getaway features an inviting Tuscan fireplace, corbel and coffered ceiling, plaster walls, and wide-plank oak floors. A sunny study, with chandelier and French doors to the rear property, along with staff quarters with bath en suite, a second bath and a powder room complete the first floor. On the second floor, the palatial master suite is in a wing of its own. It includes a romantic master bedroom with fireplace, windowed alcove and cove-lit tray ceiling; a sunny sitting room; custom fitted walk-in closets, and 2 luxurious master baths, one with infinity tub, gas fireplace, French doors to a balcony, steam shower, and oversized vanity. The other is richly paneled in mahogany and offers a steam shower, vanity and dressing area with bay window. Four additional bedrooms with designer baths en suite are exquisitely appointed. A bonus space, including a kitchenette and full bath, plus a staff/guest quarters are also on the second floor. An entertainer’s dream, the lower level presents a fun and fanciful retreat. It features a Tuscan “pub” room with imported antique walk-in wet bar with seating; an archway with glass wall opening to a climate controlled wine cellar/tasting room; a game/media room; and a lounge with access to the sunken patio with fireplace and steps up to the rear terrace. Also on this level is a kitchenette with dishwasher and refrigerator, a gym, and 2 bedrooms with baths en suite.
