The home transitions beautifully between floors, offering a main-level bedroom suite overlooking the grounds, a wine room, an exercise room, and a dedicated recreation space. The luxurious upper-level primary suite functions as a private retreat, complete with dual walk-in closets, a spa bath, and a private deck that leads directly down to the pool. The exterior grounds, designed by an award-winning landscape firm, create a private resort-like setting ideal for large-scale entertaining or quiet enjoyment of nature. A large heated pool and spa are surrounded by expansive slate patios, a brick-floored screened porch, professionally designed gardens, fruit orchards, and wide open lawns. For equestrian enthusiasts, the property features a professionally planned main barn equipped with ten matted stalls, wide aisles, a heated tack room, a wash stall, and four fenced paddocks with run-in sheds, alongside direct access to local riding trails. Adding to the property's incredible versatility is a separate two-story carriage house, which includes a fully renovated one-bedroom apartment perfect for guests or rental income, as well as a main-level woodworking shop with its own office and full bath.
