Looking for a large, private gated estate lot with the freedom to build the kind of home that most communities simply won't allow? Welcome to one of just ten exclusive opportunities within Watkins Glen Private Estates, where privacy, space, and true architectural flexibility come together. Beautifully situated on a pristine 2.3-acre wooded homesite, this custom luxury estate by Exeter Building Company is accessed through a gated entry and a long, winding private drive.. Blending timeless traditional architecture with a seamless indoor-outdoor connection, this home offers an open, airy layout ideal for both everyday living and grand entertaining. Graciously scaled rooms and refined luxury finishes define this thoughtfully designed home, where natural light pours in through dramatic floor-to-ceiling windows and every window and door is intentionally positioned to frame serene views of the surrounding landscape. The current plan features a luxurious first-floor primary suite, a private first-floor guest suite, and a gourmet kitchen that anchors generous living and gathering spaces. A massive screened-in porch with an outdoor kitchen extends the living area outdoors, creating the perfect setting for year-round entertaining. Upstairs, a large game or bonus room provides flexible space for recreation or relaxation, while additional unfinished walk-in storage and a huge walk-up third floor offer abundant room for future expansion. Complete with a four-car garage and high-end finishes throughout, this home delivers comfort, sophistication, and exceptional versatility. What truly sets this opportunity apart is the ability to fully customize the design to suit your specific vision and lifestyle. Room sizes can be expanded, layouts can be reimagined, additional bedrooms or living areas can be added, and even a separate outbuilding can be incorporated if desired. Whether you envision a larger garage, boat or RV storage, a sport court, pool, guest house, or expanded entertaining areas, the flexibility exists to create a home tailored precisely to your needs. This is more than a home, it is a rare opportunity to design and build a private luxury estate without the typical restrictions found in most communities.
