Set along a peaceful, tree-lined lane, 1174 Old Tolson Mill Road reveals a stunning, stone and brick gated estate, with award-winning landscaping by Charles Owen. This gorgeous home with over 15,000 square feet of living space designed by Arlene Christos reflects unmatched craftsmanship and elegant detailing. Offering both privacy and convenience, the property is ideally located just minutes from Great Falls National Park, Scott’s Run Nature Preserve, and the world-class shopping and dining of Tysons Corner. There is a 2-story portico with columns, a custom wood-and-glass door adorned with wrought-iron inlays welcomes you to a two story marble foyer, featuring a grand split staircase beneath a soaring mezzanine inspired by New York’s Four Seasons Hotel. The main level showcases elegant formal living and dining rooms, perfect for entertaining. The great room soars with a 24-foot ceiling and features a striking fireplace as its centerpiece. The gourmet kitchen is a chef’s dream, complete with dual center islands, custom cabinetry, and top-of-the-line appliances, including an espresso machine, warming drawer, refrigerator drawer, and wine cooler. The adjacent family room offers a cozy fireplace, a Meridian surround sound system, and direct access to the terrace, seamlessly blending indoor and outdoor living. Also on the main level, a paneled library features custom built-in shelving and a charming bay window. The guest suite offers a walk-in closet and a spa-inspired bathroom, providing both comfort and elegance. The upper level is host to the primary suite that spans more than 38 feet and feels like a five-star retreat. Its double-tray ceiling, Phantom screened balcony, outdoor hot tub, and travertine-clad spa bath create a sanctuary of comfort and style. Three additional ensuite bedrooms, each with walk-in closets, plus a large laundry room with dual washer/dryer sets complete this level.
