Set on 7.79 acres along sought-after Columns Drive, this private estate offers a rare blend of space, recreation, and convenience across from the Chattahoochee River. Originally designed as an equestrian property, the grounds feature a 5-stall barn with multiple pastures and paddock, a large private pond with fountain and dock, walking trails, tennis court, saltwater pool and spa, playground, gazebo, and greenhouse. A separate two-story carriage house presents the potential of being a guest house, office, or studio with a full bath and two-car garage accessed by its own gated service entrance. Inside the main residence, a grand entrance with dual staircases opens to generous living spaces designed for both everyday living and large-scale entertaining. The main living area overlooks the pool through walls of arched French doors, seamlessly connecting indoor and outdoor spaces. A formal dining room, private office, and an oversized primary suite with direct pool access anchor the main level. The chef's kitchen is equipped with new Italian marble, a scullery, walk-in pantry, and flows into a breakfast room and fireside family room, all with views of the pool, pond, and backyard. Upstairs, the east wing features four oversized ensuite bedrooms, while the west wing offers two additional ensuite bedrooms ideal for an au pair or in-law suite, along with laundry and a secondary staircase. A third-floor bonus level includes a full bar and half bath, well suited for a game room, theater, or entertaining space. The estate is enhanced by smart home features, a new roof (August 2025), newer high-efficiency HVAC systems, tankless water heaters, updated pool tile, Tesla chargers, and a whole-property generator capable of powering all structures. Fully fenced with two gated entrances, the property is located within the Sope Creek, Dickerson, and Walton school districts and benefits from low Cobb County taxes, with quick access to the Chattahoochee River National Recreation Area for hiking, biking, and kayaking.
