Welcome to one of Williamson County's most exceptional private estates. Set on nearly 16 breathtaking acres just minutes from Franklin, College Grove, and Arrington, this custom 7,400+ sq. ft. luxury home offers an extraordinary combination of privacy, recreation, and future opportunity. Although the address is Horton Highway, the private entrance is tucked away on quiet Tiller Lane, creating a peaceful retreat with remarkable convenience. The property is centered around a private stocked lake complete with a dock area, offering the perfect setting for fishing, kayaking, paddleboarding, or simply enjoying spectacular Tennessee sunsets. Mature trees, open green space, and incredible views create a setting that is both peaceful and unforgettable. One of the estate's most valuable features is the approved 5-bedroom soil site on the back acreage, providing a rare opportunity to build a second residence, guest house, multigenerational retreat, or luxury barn with living quarters while preserving the privacy of the existing home. Inside, generous living spaces are designed for both everyday comfort and entertaining, with expansive windows showcasing the surrounding landscape and seamless connections to outdoor living areas. Additional highlights include Greenbelt tax status, an authentic 1800s historic cabin, paved driveway, and endless possibilities for horses, recreation, or creating the ultimate Tennessee legacy property. Properties offering this combination of luxury, acreage, water, privacy, and future building potential in Williamson County are exceptionally rare. Whether you're searching for a private estate, family compound, equestrian property, or weekend retreat, this is a one-of-a-kind opportunity to own one of Middle Tennessee's most remarkable properties.
