A rare opportunity has arrived: The chance to own 10 acres on the scarce residential waterfront property that lies between Old Town Alexandria and George Washington’s Mount Vernon. RiverGate on the Potomac, designed by the noted Harrison Design Associates Architects and slated to be built by luxury home builder Horizon Builders, is a classical waterfront estate that takes advantage of this pastoral tree-lined property as it gently slopes down to the Potomac River. The magnificent French-provincial style residence is reminiscent of the grand estates built on the river a century ago, such as the storied Marwood in Maryland or Merrywood in Virginia. The seven-bedroom, 12-bath home includes soaring ceilings and wall-to-wall windows, a conservatory, a dining room that easily converts to a ballroom, staff quarters, and extensive manicured grounds with a pool, guest house, yoga studio and sport court. The property traverses a large pond on the way down to a private dock and beach with spectacular views along the Potomac River toward a wooded Maryland shore. Imagine yourself living on this historic property, which George Washington once owned as part of his 1,800-acre River Farm, the northernmost of the five farms that comprised his sprawling 18th-century estate. Here on this placid shoreline, you’ve got the opportunity to blend your own history and traditions with those of our founding father.
