Units n/a

Exclusive and private estate on approximately 9 acres of breathtaking property. Own a slice of heaven at this sanctuary residence, offering a 4-bedroom main home, luxurious pool house, professional equestrian facilities with 4-stall stable and lighted dressage arena, over 7 acres of manicured gardens and landscaping, natural creek frontage, multiple waterfalls, 4 serene ponds, garages for 10+ vehicles, and a showpiece climate-controlled greenhouse. With more than a dozen thoughtfully designed structures-including a guest barn apartment, chapel, pavilions, and extensive entertaining spaces-this estate is a rare blend of lifestyle, beauty, and functional luxury. The main residence spans 3,975 sq ft and includes 4 bedrooms, 3.5 bathrooms, and 2-car attached garage. Recent upgrades include two new hot water heaters (2023 and 2025), HVAC systems (2024), and a new roof with upgraded insulation (2020). Interior highlights include a Viking range, jetted double-sized Jacuzzi tub in the primary suite, central vac, home theater, and mirrored gym. The 1,620-square-foot pool house serves as an entertainer's dream, with loft-style bedrooms and a chef's kitchen outfitted with Wolf appliances, warming drawer, 2 dishwashers, 2 microwaves, and custom refrigeration drawers. A central bar with cabinetry, dishwasher, ice machine, and a 25-foot dining table sets the stage for large gatherings. The 55,000-gallon gas-heated UV-ozone pool (no salt or chlorine) includes 3 in-pool benches, 2 waterfalls, and an in-ground cleaning system. The pool was resurfaced in 2018, with a new heater and filter added in 2022. The equestrian facility features a 4-stall stable with climate-controlled tack room and office, separate shavings shed, feed room, 2 hot/cold water wash racks, and a fly spray system. The lighted 60' x 100' dressage arena offers excellent drainage, sprinklers, and all-weather footing. 7 fenced paddocks and pastures, 3 with run-in sheds, connect to over a mile of private horse and walking trails. The barndominium offers a flexible 1,685-square-foot layout with acid-stained garage flooring on the main level, space for two vehicles or as a party barn, plus a built-in bar. Upstairs, a guest studio apartment opens to a deck overlooking the arena. Both levels feature vintage-style refrigerators. Constructed in 2019, the estate's chapel includes stone benches, a wishing well, gardens, and an observation deck with mountain views. The climate-controlled greenhouse complex is a showstopper-ideal for any Master gardener-with two high-end structures connected by a cedar-lined atrium with skylights, low-E glass, motorized hydraulic roof vents, HVAC, and automated watering. A koi pond, waterfalls, and olive tree orchard bordered by stone walls surround the space. Systems include 108+ irrigation zones fed by two deep wells, app-controlled lighting, irrigation, security, and audio, and solar panels generating up to 30 kWh monthly. Nearly 60 security cameras monitor the grounds, while Sonos audio plays across 12 outdoor zones. Landscape lighting includes 50 moonlights and path uplights for evening ambiance. Also included: a detached 7-car garage with storage loft, finished tool shed with workspaces, two large dog runs (indoor and outdoor), playground, hot tub, and a chicken coop. Outdoor entertaining includes a lighted pavilion with bar, outdoor TV, adjacent catering kitchen, and a regulation-size bocce court with scoreboard. The Creek Garden features 3 gazebos, 10 contemplative garden areas, stone benches, a waterfall, and interconnected trails. A climate-controlled outhouse with skylight, storage buildings, and trailer parking meet every need without sacrificing beauty. This is more than a home-it's a living, breathing work of art designed for elegant living, grand entertaining, and serene escape. Properties offering this depth of design, privacy, usable land, and quick access to Atlanta and Buckhead are nearly impossible to find.
