UPSCALE CASUAL ELEGANCE! Private and serene, this gated Estate sits on 2 acres of expertly landscaped, lush surroundings with extensive outdoor living options, including a slate-covered back terrace overlooking a spectacular Charles Owens waterfall feature. This stunning home, custom-built by renowned local luxury builder, Hans Schmidt's Winthrop Custom Builders, has more than $400K in upgrades with high-end finishes and designer details throughout the more than 8,500 sq ft of living. The drama of the two-story foyer leads you through the spacious rooms with soaring 10 ceilings, including a formal dining room, expansive gourmet kitchen, with separate morning room and great room with beamed ceiling and stone fireplace. Continuing through the main level, an oversized combination living room-library features a large fireplace, built-in floor-to-ceiling bookcases, and is surrounded by windows, giving you an expansive view of the professionally landscaped gardens. French doors from the great room and kitchen morning room connect you with the outdoors, with multiple seating options for enjoying the stunning waterfall feature. The flow is perfect for both formal and informal entertaining, inside and out. The stunning owner's suite has a large balcony, which overlooks the gardens and waterfall. Architectural details include the barrel-vaulted ceiling, imported light fixtures, exquisitely customized his and hers walk-in closets with dressing area and built-in wardrobe, and luxury modern Porcelanosa master bath. The upper level includes three additional spacious en suite bedrooms with upgraded bathrooms and walk-in closets, as well as an oversized laundry room. The walkout lower level offers a kitchenette with bar, media/exercise room, wine closet, huge recreation room with gas fireplace, and an office that could be converted back to a bedroom. All of this without sacrificing an incredible amount of storage! The grounds offer a wrap-around lawn with gardens at every turn - with plenty of places to gather, or simply enjoy on your own; and even space for a future pool! For outdoor enjoyment away from the house, Great Falls National Park is just 2 miles down Old Dominion with hiking paths along the Potomac River with spectacular views of the Falls. This property is both private and conveniently located - just minutes to all the shops, restaurants, and activities of Tysons and downtown McLean, with easy access to all the finest that Washington DC has to offer. Ideally located centrally to both Reagan and Dulles International Airport.
