This is the largest estate for sale in Westchester County

A massive Hudson Valley estate, built in the 1930s by a famed child psychiatrist and his retail heiress wife, is on the market for the first time in more than two decades.

The $6 million listing, called Rolling Stone Farm, is just an hour’s drive from Manhattan. It spans more than 106 rolling acres, hosting storybook cottages and extensive equestrian facilities. Its size makes it the largest estate currently for sale in Westchester County.

Will Stuart of Berkshire Hathaway HomeServices holds the rare offering. 

“It’s really a once-in-a-lifetime opportunity for someone to be this close to New York City on the Hudson River,” Stuart said. “There’s no comps to this. These properties just don’t exist.”

The estate was built in the early 1930s by Dr. David M. Levy and his first wife Adele Rosenwald. The couple chose Croton-on-Hudson for their home, a village within the town of Cortlandt known for picturesque parks and the scenic the New Croton Dam, which supplies New York City with its famously clean tap water.

Levy, a pioneer of child psychiatry, introduced the Rorschach test to the US and coined the term “sibling rivalry,” according to his New York Times obituary.

Levy’s unique personal office, an octagonal stone library, remains original to the property. 

His wife, Rosenwald Levy, was the philanthropic daughter of the longtime president and owner of Sears, Roebuck and Company, Julius Rosenwald. Adele notably raised $170 million to aid Holocaust survivors in 1947, according to the Jewish Women’s Archive. 

The Levys built an impressive spread — at its center sits the European-style main house.

The romantic stone and wood-shingle exterior is matched by richly appointed interiors, with wood-paneled walls, wide-plank floors and leaded glass windows. 

The three-bed home includes a primary suite with vaulted ceilings, a walk-in closet and a marble bath. A guest annex attached to a four-car garage adds two extra bedrooms to the spread. A guest cottage elsewhere on the property offers additional space for guests.

“You’re overlooking the Hudson River, there’s lush gardens, gorgeous stone architecture. There’s just nothing like it,” said Stuart. 

Rolling Stone Farm is still used as a weekend getaway by its current owners, Stuart said, but it was previously a bustling equestrian estate with more than 20 horses. Facilities include an 1800’s two-story barn, a two-bedroom grooms’ apartment and an outdoor riding arena. 

Non-equine amenities include a 45-foot pool and a tennis court. The grounds also boast a professionally landscaped English garden and ancient trees.

“It just feels like a fairy tale when you’re there,” Stuart said.

The entire estate last sold for $2.25 million in 2000, according to property records. A 2004 sale for $1.35 reportedly marked a single-parcel buy-out within the family.

Now, after 25 years, it’s time for somebody else to get their Hudson Valley happily ever after.
