521 Barrett Hill Road Overview

Time on Site:
86 days

Half Moon Farm Set on over three idyllic acres in the heart of the Hudson Valley, this exquisitely restored 19th-century farmhouse offers a rare blend of historic charm and thoughtfully curated modern living. Originally dating to the early 1800s, the historically registered residence has been meticulously updated while preserving its authentic character, including original wood floors, classic proportions, and a warm, inviting atmosphere throughout. The home features three bedrooms and two baths with interiors designed to maximize natural light and seamless indoor-outdoor flow. A gracious entry leads to a sun-filled living room anchored by a wood-burning fireplace, complemented by a cozy reading nook, custom built-ins, and direct access to a covered patio wrapped in climbing grape vines—a sun-kissed haven perfect for quiet mornings or evening entertaining. This enchanting outdoor space adorns an organic herb garden growing rosemary, oregano, thyme, basil, lavender, dill, chives, sage and lemon balm, between the roses and butterfly bushes. The entrance to the garden was intentionally adorned with honeysuckle, in order to invite the hummingbirds. The updated kitchen pairs rustic sophistication with functionality, showcasing custom cabinetry, butcher block countertops, and stainless-steel appliances. The kitchen is further complemented by an expansive, well-appointed pantry offering exceptional storage. The grounds are equally enchanting and the ample acreage is suited for the addition of guest cottages. Mature maple trees— some of which were 200 to 300 years old —frame a serene bluestone saltwater pool set within a former sheep paddock. Lush gardens with organically curated soil feature aromatic herbs, vegetables, flowering roses, and restored stonework. This private oasis fosters a natural sanctuary where eagles, screech owls, rabbits, indigenous tortoises and turkey families are frequently spotted. Additional highlights include a finished lower level with heated floors, a recreation space, and direct access to the landscaped backyard, as well as auxiliary structures including a sizable garden shed. This one-of-a-kind country escape embodies a rare opportunity to own a storied property where history, design, and nature exist in perfect harmony. One hour drive from Manhattan and just down the road from the Sedgewood Club Beachfront & Golf Course.
