Home for Sale, 523 Long Beach Road, Smithtown, New York 11780

Final town approvals granted and full CO's just issued on March 3rd, 2026

Discover this stunning newly built estate offering 8,500 square feet of beautifully designed living space, set on two peaceful acres in the heart of Nissequogue. Every detail of this home is brand new and thoughtfully crafted with a newly constructed 3 car garage and utility room, with all architectural plans approved and overseen by the Village to ensure exceptional quality and design.

The home features six bedrooms, five full bathrooms, and two half baths, along with a custom-designed tower that adds a truly unique touch. The open layout creates an easy flow between formal and casual spaces, making it just as comfortable for everyday living as it is for entertaining.

The chef’s kitchen sits at the center of the home and includes a custom pantry, built-in wine storage, and a wet bar — combining style with everyday practicality. Just off the kitchen, the spacious living and dining areas are warmed by two fireplaces — one gas and one wood-burning — setting the tone for cozy evenings or larger gatherings.

The primary suite and junior suite each feel like private retreats, with heated bathroom floors, generous walk-in closets, and spa-inspired finishes. Engineered white oak floors and custom stone countertops run throughout the home, highlighting the attention to detail at every turn.

Outside, a beautiful paver patio surrounds the 20x40 heated saltwater pool with stadium steps — perfect for relaxing or hosting outdoors. The home also includes a dedicated A/V room with CAT-6 wiring and whole-home automation capability.

Comfort and efficiency are built in, with WiFi-enabled climate controls, a four-zone central air system, and a 1,000-gallon buried propane tank. Additional upgrades include 400-amp electrical service with an automatic transfer switch for a future generator and a 23-zone WiFi-enabled irrigation system.

Quality is evident throughout — from Andersen 400 Series windows and James Hardie V-groove siding to premium fixtures and finishes. A three-car garage, hardwired Ring camera system, deeded private beach access, and a half-circular driveway with dual Belgian block aprons complete the property.

This is a rare chance to own a brand-new, meticulously overseen estate in one of Long Island’s most desirable communities — where luxury living meets timeless design.
