Putnam Valley, NY 10579

Set on nearly 60 acres of extraordinary land in Putnam Valley, this is a rare and remarkable opportunity to own a private retreat of true scale—where natural beauty, curated gardens, and future possibilities converge. Backing directly to Fahnestock State Park, the property enjoys permanently protected surroundings, creating an uninterrupted backdrop of forest, sky, and seasonal color. From the moment you arrive, the setting is captivating. A long, private driveway leads you through a landscape rich with mature trees, expansive lawn, and beautifully maintained gardens that serve as a true highlight of the property. Thoughtfully designed and lovingly cared for, the gardens feature a tranquil fountain that adds a soothing soundtrack to the outdoor experience. A meandering walking trail winds through the woods for approximately 1.5–2 mile loop, offering a peaceful and immersive connection to nature, while elevated vantage points provide sweeping views. A charming pond—once used for winter skating—awaits your vision as a reimagined centerpiece of outdoor living. Beyond its natural beauty, the property presents compelling future potential. Previously approved subdivision plans for seven lots have expired but may offer an opportunity for renewal, subject to appropriate approvals and due diligence—making this not only a serene retreat but also a strategic investment. Built and meticulously maintained by its original owner, the nearly 3,900-square-foot Colonial home is perfectly positioned within this idyllic setting. A dramatic two-story entry welcomes you, with formal living and dining rooms flowing seamlessly into the heart of the home. The formal living room features a fireplace, while the family room—also anchored by a wood-burning fireplace—opens to a spacious kitchen with granite countertops, a new white subway tile backsplash, and comfortable cork flooring—ideal for both everyday living and entertaining. Step outside to the expansive screened-in porch, enhanced with low-maintenance composite decking, where meals, morning coffee, and quiet evenings are elevated by the surrounding gardens and the peaceful sounds of the fountain and nature. The main level also includes a powder room, laundry area, garage access, and a secondary staircase leading to a versatile bonus room. Upstairs, four generously sized bedrooms include a truly special primary suite, along with a dedicated office providing flexibility for today’s work-from-home lifestyle. The upper level also features an expansive multi-purpose bonus room, offering exceptional flexibility for recreation, media, guests, or additional workspace. The primary suite includes two walk-in closets and a recently renovated spa-like bath featuring radiant heated floors, a freestanding soaking tub, and a glass-enclosed shower. Additional recent upgrades include a newer roof and the installation of an EV charging station, blending modern convenience with timeless country living. Despite its peaceful, retreat-like setting, the location is highly convenient—within commuting distance to New York City and close to major highways, shopping, and the scenic Hudson River.
