Set on 3.25 private acres of lush formal gardens and mature woodlands, this one-of-a-kind Chappaqua residence is a rare architectural treasure. Designed in the 1930s by renowned Westchester architect James Renwick Thomson, the home blends refined sophistication with warm, inviting charm--offering an unparalleled living experience just minutes from the heart of town. From Palladian windows and vaulted ceilings to Dutch doors, rough-hewn beams, copper gutters and exquisite custom woodwork, every detail speaks to the home's timeless character. Light floods the interiors through bay windows, while a second-floor terrace invites al fresco dining overlooking the serene landscape. Outdoors, the grounds are truly spectacular: meandering pebbled pathways wind through formal gardens with multiple sitting areas, two tranquil koi ponds, and a meandering stream. A red clay tennis court (easily restored) adds a resort-like touch, and the long, private driveway ensures a secluded retreat. Located within the award-winning Chappaqua School District and close to town, train, schools and swim and tennis clubs, this property offers both privacy and practicality. Commuting to NYC is a breeze--just a short drive or train ride away. Low taxes. DRIVEWAY ON TURNER DRIVE. Timeless Elegance Meets Tranquil Living - Don't miss this unique offering!
