ONE OF NEW YORK'S MOST COVETED ESTATES. Enter a world where timeless elegance meets state-of-the-art luxury. Originally built in 1901 for renowned financier J. Borden Harriman, this legendary estate - historically known as Devonshire, and earlier as Uplands - stands as a rare example of Gilded Age grandeur, reimagined for modern living. When it last sold in 2012, it set a record as the highest residential sale in Westchester County history - an extraordinary testament to its significance and stature. Set on more than 100 acres of pristine landscape, the property offers exceptional scale, privacy, and breathtaking natural beauty, all within easy reach of Manhattan. Rolling meadows, sweeping vistas, and picturesque terrain create an unparalleled setting suited for equestrian pursuits, recreation, and refined country living. A substantial expansion is already underway, offering the next steward a rare opportunity to complete the vision, by selecting finishes, materials, and design elements tailored to their unique lifestyle. Several accessory buildings, elegantly renovated, provide ideal accommodations for guests, staff, and a range of lifestyle needs. Estates of this magnitude, provenance, and proximity seldom become available. More than a grand residence, this is a legacy property and enduring asset ready to be shaped for generations to come. 2-Acre Zoning. Square Footage is for main house only and does not include outbuildings.
