Description
660 Chicken Valley Road | Locust Valley, Long Island Gold Coast
Positioned within the most coveted enclave of Locust Valley on Long Island’s historic Gold Coast, 660 Chicken Valley Road is not merely a residence—it is a private estate of enduring significance, designed for a highly discerning buyer who values legacy, discretion, and uncompromising quality.
Set across approximately 5.33 acres of secluded, manicured grounds and encompassing nearly 16,500 square feet of interior living space, the estate embodies a rare combination of architectural integrity, refined craftsmanship, and long-term asset strength—an offering seldom available in today’s market.
Architectural Integrity & Engineering Excellence
The residence far exceeds conventional residential standards, delivering exceptional structural durability and long-term stability.
Every element—from roofing systems to drainage engineering, from acoustic insulation to thermal efficiency—has been executed to a near commercial-grade level, ensuring the property performs as beautifully as it presents over time.
A fully integrated geothermal heating system, paired with advanced climate and humidity control, provides year-round comfort while preserving fine art, furnishings, and materials at an optimal level.
Smart home integration allows full remote operation globally, supported by central vacuum, multi-zone climate control, and a whole-house generator—ensuring seamless living without compromise.
Security and privacy are paramount, with dual gated access, an extended private drive, and discreet contingency features that elevate the estate to a level of true residential security.
Interiors | Bespoke Craft, Quiet Luxury
The interior experience is defined not by excess, but by precision.
From hand-finished hardwood floors to finely executed crown moldings, each detail reflects a commitment to craftsmanship that is increasingly rare.
The kitchen and service areas are appointed with best-in-class appliances—including Wolf, Sub-Zero, and Miele—integrated with custom millwork and carefully selected stone surfaces. These spaces function equally as a private culinary environment and a sophisticated setting for entertaining.
The primary suite is conceived as a private retreat, featuring a fireplace, a fully appointed dressing room, and a spa-caliber bathroom with radiant heated floors, a freestanding soaking tub, and a multi-function shower system—delivering a daily experience of understated indulgence.
Technology is seamlessly embedded throughout the home, integrating lighting, climate, and security into a unified system that supports effortless, modern living while preserving warmth and timeless character.
Grounds | A Private Landscape of Distinction
The estate grounds offer a level of scale and privacy rarely achieved.
A defining feature is the approximately 2,000-foot cherry blossom-lined drive, creating a seasonal spectacle that transforms the approach into an experience of quiet grandeur—both cinematic and deeply personal.
The landscape unfolds with expansive lawns, mature trees, and curated outdoor environments designed for both solitude and large-scale entertaining. Recreational amenities further enhance the lifestyle offering, positioning the estate as a true private resort.
Location & Investment Perspective
Locust Valley remains one of the most tightly held and supply-constrained markets on the Gold Coast. Properties of this caliber—combining land scale, construction quality, and privacy—are increasingly rare.
This offering represents not only a primary or secondary residence, but a strategic long-term asset with strong preservation of value and generational appeal.
660 Chicken Valley Road is not defined by square footage alone, but by what it represents.
It is a residence for those who understand that true luxury is not declared—it is recognized.
Here, ownership is not simply acquired. It is inherited forward.
