Welcome to 365 Split Rock Road...
Set within one of the North Shore of Long Island’s most desirable enclaves, this gated estate in Syosset offers an exceptional balance of privacy, scale, and modern design. Recently constructed and thoughtfully sited on five private acres, the residence encompasses over 12,000 square feet of well-proportioned living space, creating a quiet retreat defined by quality and permanence.
The main residence is designed to accommodate both comfortable daily living and effortless entertaining. It features six bedrooms and six and a half bathrooms, including a spacious primary suite with private quarters. The home is anchored by a chef’s kitchen equipped with Wolf and Thermador appliances, generous entertaining areas, a wood-burning fireplace, and a covered outdoor living room that seamlessly extends the interior living space. Fully finished basement to further enhance flexibility and convenience.
The grounds are both functional and refined, offering a pool area with a separate cottage or guest house, tennis and basketball courts, a private pond, dog run, and a five-car garage. Mature landscaping is supported by substantial irrigation and drainage systems, ensuring the property remains well maintained throughout the seasons. Additional features include a whole-house gas generator, comprehensive security and surveillance systems, and robust infrastructure throughout the estate.
Located within the highly acclaimed Syosset Central School District—renowned for its academic excellence and consistently ranked among the top districts on Long Island—the property offers both an exceptional lifestyle and long-term value.
