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.
