Nestled behind a gated entry on nearly three private acres in Armonk, this stately brick colonial offers a world of refined luxury and total seclusion. The property blends timeless architecture with modern sophistication—and delivers resort-caliber living at every turn. Outdoors, the amenities riv...al any private club: a regulation tennis court with pickleball lines, sparkling in-ground pool with adjacent spa, and a fully outfitted outdoor kitchen and dining pavilion -perfect for alfresco entertaining all year round. A cozy firepit lounge sits under the canopy of mature trees, ensuring privacy and tranquility. Inside you are greeted by fully renovated interiors. Every detail has been thoughtfully curated—from the sleek, contemporary finishes to the rich textures of custom woodwork and classic architectural accents. Soaring ceilings and oversized windows bathe the expansive living areas in natural light, highlighting exquisite finishes – from gleaming hardwood floors and substantial millwork – all testaments to the home’s artisanal detail. The gourmet chef’s kitchen is a showpiece unto itself, featuring top-of-the-line appliances, custom cabinetry, and a vast quartz-topped center island which flows seamlessly into a sun-drenched two-story family room. For formal occasions, enjoy the elegant dining room and gracious living room with fireplace. The first-floor office/library offers a private escape for work or reflection. Integrated smart-home automation allows seamless control of lighting, climate, and security with the touch of a button. Additional highlights on the first floor include a mudroom/laundry room and a guest/au pair bedroom with a separate entrance. Ascend the grand staircase to discover luxurious private quarters. The primary suite is a haven of indulgence, boasting its own fireplace, oversized closets, and a spa-inspired bath clad in marble. Each additional bedroom is oversized with its own ensuite bath- except for two that share a stylish Jack and Jill bathroom. With flexible bonus spaces including a dedicated art room and playroom. Leisure and wellness take center stage on the lower level. Enjoy cinematic experiences in the custom home theater, wet bar, fully equipped home gym, therapeutic infrared sauna or unwind in the dedicated massage and wellness room. The estate is as functional as it is beautiful. Designed for both grand entertaining and intimate everyday living, this exceptional property seamlessly merges indoor and outdoor luxuries to create an unparalleled lifestyle experience. A long, tree-lined, double width driveway leads to an attached three-car garage. Just minutes from Armonk’s charming downtown and situated within the highly sought after Byram Hills School District. With a commute of under an hour to the heart of Manhattan, you can truly enjoy the best of both worlds: tranquil country living with easy access to the city. In every sense, 839 Mount Kisco Road is a one-of-a kind retreat that exemplifies luxury living at its finest. Continue reading
