About this home

Gracing an impressive 4.28 acres overlooking the Hudson River, this exceptional nine-bedroom Tarrytown estate offers a rare combination of historic character, resort-style living, modern sophistication, and timeless elegance. Built in 1929 and affectionately known as Whitehall, the residence has been meticulously updated and maintained, preserving its architectural integrity while embracing the comforts, style, and expectations of today’s most discerning buyer. Spectacular water views span the entire home, providing an extraordinary backdrop for Hudson River sunsets. Distinctive gates mark the entrance to a private approach through beautifully landscaped grounds designed for a resort-caliber lifestyle, featuring a private pool and hot tub, expansive terraces, an impressive pool house with full kitchen, recreation room, steam and outdoor showers, private tennis court, tranquil pond, mature gardens, and winding stone paths. Inside the 8,329-square-foot haven, stained glass, arched openings, sweeping verandas, striking wood paneling, stately fireplaces, wrought-iron details, hidden doors, and other distinctive architectural elements preserve the home’s heritage, while thoughtful updates create a seamless blend of historic character and contemporary luxury. At the heart of the home is a magnificent, all-new kitchen with exquisite hand-selected quartz countertops, custom cabinetry, and top-of-the-line appliances. The generous floor plan offers gracious spaces for everyday living and entertaining, including a formal dining room, butler’s pantry, breakfast area, expansive screened porch overlooking the Hudson, and versatile spaces ideally suited for home offices or studies. All nine bedrooms are beautifully appointed, while the luxurious primary suite features a spacious ensuite bathroom with high-end finishes, a walk-in closet with custom built-ins, a meditative sitting room, a wood-burning fireplace, and a Juliet balcony with spectacular water views. New windows were recently installed complementing the home’s thoughtful updates, including beautifully refinished wood flooring, a reverse-osmosis water filtration system, and an eero mesh Wi-Fi system providing seamless whole-home connectivity. A sophisticated climate-control system with 17 HVAC zones provides year-round comfort throughout and a generator offers added peace of mind. A three-car garage, upper-level laundry, and expansive driveway add modern convenience. With direct access to the Old Croton Aqueduct and close proximity to Patriots Park, Wilson Park, Tarrytown Lakes, Tarrytown, and Sleepy Hollow, Whitehall is an unparalleled private Hudson River oasis offering a lifestyle of extraordinary beauty, privacy, and distinction.
