This is control. This is coastline. This is consequence. Rising above Cold Spring Harbor in Laurel Hollow, this Hamptons-caliber estate commands a full horizon line to Connecticut—clean, uninterrupted, and impossible to replicate. Sixty minutes from Manhattan yet entirely removed. Privacy here isn't marketed. It's built in. The architecture is disciplined and exacting. Estate scale without waste. Every primary space is engineered toward the water—light, line, and perspective working in concert. Glass walls eliminate barriers. Multi-tiered decks step down with intent to a private beach. The transition from interior to exterior is seamless, deliberate, and rare. The kitchen is not secondary—it's central. Dual islands. Professional-grade appliances. A fireside seating zone that holds the room. This is where movement happens, where people stay longer than planned. The great room delivers immediate impact—volume, light, glass, horizon. Sightlines stay open. The water remains constant. Access to the decks is direct and uninterrupted. The library shifts tone. Controlled. Quiet. Custom millwork, tailored built-ins, and a statement fireplace create a true executive environment—private, focused, decisive. Five en-suite bedrooms are positioned for separation and autonomy. The primary suite operates as its own tier—refined finishes, spa-level design, and elevated harbor views that reset perspective daily. A temperature-controlled wine cellar with tasting area introduces ritual. A fully realized media room delivers immersion without compromise. And then, the unexpected: a custom indoor garden anchored by a sculptural stone waterfall—architectural, calming, and rarely executed at this level. Four-car garage. Advanced mechanical infrastructure. Cold Spring Harbor School District No. 2. This is not a seasonal house. It's a year-round position—equally suited for sustained living or precise weekend entry and exit. North Shore waterfront at this scale, with this clarity, does not circulate often. Shown exclusively by private appointment.
