About This Home

517A Old Chappaqua Road

Perfectly positioned on just shy of one acre and backing the serene wooded grounds of the Edith Macy Center, this residence blends privacy, prestige, and natural beauty. A rare opportunity exists to fully customize finishes, materials, colors, and upgrades — allowing you to curate a home that reflects your personal vision and lifestyle. Upon entry, a dramatic double-sided staircase with an architectural catwalk creates a breathtaking focal point. Thoughtfully designed with 9-foot ceilings throughout and a soaring 20-foot cathedral ceiling in the family room, the home offers grand scale and open, light-filled living spaces. A statement fireplace anchors the family room, creating warmth and sophistication. The state-of-the-art chef’s kitchen will feature premium appliances, custom cabinetry, quartz countertops, and expansive workspace ideal for entertaining and everyday luxury living. Upstairs, generously proportioned bedrooms provide comfort and privacy, with the option to finish a bonus room tailored to your needs — whether a media lounge, private office, or fitness studio. The primary suite will serve as a tranquil retreat with spa-inspired bath potential. Additional exceptional features include: 3-car garage, expansive rear patio for seamless indoor/outdoor entertaining, large unfinished lower level, plumbed for future bath and endless possibilities, pool site potential in the rear yard. The home will be strategically set back and elevated on the property to maximize privacy, presence, and curb appeal. Driveway will be completely redone and re-pitched.
