Discover New York's Priciest Estate: A $125 Million Equestrian Paradise

Located in the luxurious Water Mill, New York, a stunning estate is now the most expensive property up for grabs in the state, commanding a staggering $125 million.

Resembling a scene from a classic novel, this grand estate is equipped with a vast horse training facility, boarding barns, polo grounds, and a 20,000-square-foot main house crafted by renowned Hamptons architect Jeffrey Collé.

A Luxurious Marvel on the Market

On sale through Bespoke Real Estate, this extraordinary compound in Water Mill outshines even the most opulent New York City penthouses and other high-end Hamptons properties currently available.

While its price tag is significant, it pales in comparison to the costliest residential deal in U.S. history: Ken Griffin's $238 million purchase of a penthouse in Manhattan in 2019.

An Expansive Domain in the Hamptons

Nestled over 80 acres, the estate is the largest equestrian property in the Hamptons, divided into three parcels set amidst protected farmlands and conservation areas.

Records reveal that developer Ben Ashkenazy and his spouse acquired this extraordinary property for a collective $26.7 million in separate transactions during 2015 and 2016.

Privacy Amidst Nature

Positioned between Southampton and Bridgehampton, Water Mill is celebrated for its scenic farmlands, oceanfront views, and unobtrusive luxury homes.

Just moments from the coastline, marinas, and charming Hamptons villages, the estate offers access to sophisticated dining, artisanal produce markets, and upscale shopping.

Equestrian Excellence

Showcasing a comprehensive horse farm, the estate features top-tier boarding stables, paddocks, and advanced training amenities—rare even among the Hamptons' finest properties.

A Masterpiece by Jeffrey Collé

Collé, a prominent name in the Hamptons' bespoke home industry, is credited with designing the mansion that includes clients from Wall Street to Hollywood celebrities such as Alec Baldwin and Billy Joel.

Living Space Galore

The main home boasts 20,000 square feet with eight bedrooms, nine full bathrooms, and four powder rooms, blending contemporary sophistication with classic Hamptons charm.

Designed for Both Comfort and Entertainment

Expansive living and dining areas flow seamlessly into wide decks and terraces, perfect for summer soirées with breathtaking vistas of the serene surroundings.

Historic Touches Inside

Featuring nine wood-burning fireplaces imported from historical French chateaus, the house's luxurious features don't end here. Each bathtub is uniquely carved from Verona stone, with residual material enhancing the floors and kitchen countertops.

Resort-Grade Outdoor Spaces

Enjoy the breathtaking panoramic views from the estate's extensive patio and terrace. Architectural columns infuse the outdoor setting with grandeur and sophistication.

Poolside Leisure

A heated gunite pool measuring 25 by 50 feet is perfect for relaxation, complemented by an adjacent cabana complete with bar seating, facilitating ultimate leisure by the poolside.

Tennis and Gardens

The estate features a secluded sunken tennis court designed for ideal gameplay shielded from winds, surrounded by lush, manicured gardens.

Pinnacle Farm: Equestrian Haven Included

The sale encompasses Pinnacle Farm, a top-tier equestrian facility boasting indoor and outdoor riding arenas, jumping courses, a storage barn, and accommodations for over 20 horses. It's deemed a utopia for horse enthusiasts.

Water Mill: A Quiet Gem on the Rise

Although not as renowned as Montauk or East Hampton, Water Mill is gaining traction as an exclusive, tranquil enclave for a quintessential Hamptons lifestyle.

According to Zillow, the average house price in Water Mill stands at $4.7 million as of September 2025, marking a 2.9% increase from the previous year.
