Maison Blanche: An Architectural Icon in Upper Brookville Experience the pinnacle of ultra-modern luxury at 31 Chestnut Hill Drive. Set on five flat, private acres at the crest of a premier cul-de-sac, this architectural sanctuary was originally designed by the renowned architect Gary Gallagher and redesigned by award-winning FAIA architect Stuart Narofsky, leading to an extensively renovated (2023–2026) masterpiece. The residence features six bedrooms with en-suite bathrooms, four additional half-baths, to include an expansive first-floor primary suite. Architectural highlights include two custom floating staircases with glass railings, porcelain and white oak floors, and frameless full-bodied Belldinni doors. The chef’s kitchens in the main and guest houses are equipped with Wi-Fi-controlled Thermador appliances and specialty quartz islands. Uniquely designed for wellness and entertainment, the second-floor features 3 bedrooms and a private gym and Finnish sauna, while the lower level boasts a Dolby-Atmos theater, wine tasting room, a yoga/massage spa, and a wet bar. Outside, a heated saline pool and spa are framed by a porcelain patio and an unobstructing glass railing, and an outdoor wet kitchen. App-controlled for the modern age, the estate features smart management of the custom steel entry gate, five-zone HVAC, motorized shades, security, and a whole-house generator. This is the new standard of Gold Coast living.
