Nestled at the end of a private, gated lane, 9185 Old Dominion Drive is perfectly located on a premier lot with two-and-a-half acres of gardens and woodlands and the soothing sounds of Great Falls and the Potomac River. Designed by renowned restoration architect Carroll C. Curtice, the residence exudes old-world charm with a timeless brick exterior and elegant, arched windows. With more than 6,250 sq ft of living space, the floor plan features generously sized rooms for entertainment, trimmed with exquisite custom mouldings. The home is within walking distance of Great Falls Park and is easily accessible to the 495 Beltway, as well as to the villages of McLean and Great Falls. The circular drive with outdoor parking (ten-plus cars) guides homeowners and guests into the two- story, marble foyer with dramatic curved stairs and a crystal chandelier. A large Palladian window illuminates the foyer. Grand entertaining is possible with an extensive living room featuring a beautifully detailed fireplace with marble surround and intricately designed crown moulding and architraves. Glass doors lead out to the Vermont-slate rear terrace. With gorgeous views of the rear gardens, the terrace boasts three sets of glass doors leading into the living, dining and family rooms.
