Description

Escape to a private country estate where timeless architecture, extraordinary craftsmanship, and resort-inspired amenities come together to create an exceptional lifestyle. Set on 35 acres, this remarkable property offers a level of privacy and tranquility rarely found within an easy drive of Syracuse, Skaneateles, and Ithaca. Originally transformed through an extensive renovation in 2017, the main residence offers over 4,000 square feet of beautifully designed living space. At its heart is a spectacular chef's kitchen featuring an expansive island, Sub-Zero refrigerator, Wolf range, granite countertops, farmhouse sink, and custom cabinetry. The dramatic two-story great room is anchored by a soaring stone fireplace and opens through a stunning Pella accordion door to an outdoor oasis designed for effortless entertaining. The backyard is nothing short of extraordinary. A stunning in-ground gunite pool, expansive patio and deck, and curated specimen gardens create an atmosphere that feels more like a private retreat than a residence. The main residence also includes a grand two-story foyer with a sweeping curved staircase, elegant formal living and dining rooms, four bedrooms, two-and-a-half baths, first-floor laundry, a finished lower level with wet bar, and an attached three-car garage. Adding exceptional versatility to the estate is a detached multi-car garage with a beautifully appointed 1,107 square foot carriage house residence above. Completely renovated in 2025, this private living space features a new kitchen, updated bathroom, great room with a view, two bedrooms, laundry, and a private deck overlooking the grounds. Ideal for extended family, guests, caregivers, an au pair, multigenerational living, or a sophisticated home office retreat, it offers complete independence while remaining seamlessly connected to the estate. An additional outbuilding enhances the property's functionality, providing generous space for storage, equipment, hobbies, or a private workshop. More than a home, this is a destination property—an opportunity to enjoy the peace and privacy of a secluded country retreat without sacrificing convenience.
