Set on more than 13 breathtaking estate-like acres in the heart of Katonah, this extraordinary gated retreat offers an unparalleled blend of luxury, privacy, and natural beauty. Tucked away behind a long private drive and surrounded by mature specimen trees, rolling park-like grounds, and picturesque seasonal reservoir views, the property feels worlds away while remaining just minutes from the train and major highways for effortless access to Manhattan. Designed with both elegance and comfort in mind, the sun-filled interior showcases soaring 10-foot ceilings, expansive windows, and wide-plank oak flooring throughout. The open-concept floor plan creates seamless flow for everyday living and entertaining, anchored by a spectacular chef's kitchen outfitted with premium Thermador appliances, custom cabinetry, generous prep space, and a spacious sitting area overlooking the patio and serene reservoir beyond - the perfect setting for morning coffee or unforgettable sunsets. The thoughtfully designed first floor features a luxurious primary suite with a spa-inspired bath, an additional bedroom, and two beautifully appointed full bathrooms. Upstairs, two more spacious bedrooms and another full bath provide ideal accommodations for guests. Extensively renovated from top to bottom, this turnkey residence includes numerous upgrades such as a new roof, bluestone front steps, energy-efficient windows, and quality HardiePlank siding. Adding to the home's unique appeal is a spectacular glass-enclosed, heated indoor pool offering year-round enjoyment. For buyers seeking alternative possibilities, the seller is willing to remove the enclosure to create an outdoor pool experience or fill the pool entirely. Whether embraced as a private country sanctuary or explored for its subdivision potential, this remarkable Katonah estate presents a rare opportunity to own an exceptional property in one of Westchester's most coveted settings.
