The most expensive home in Northern Virginia is also on a large piece of property.  Listed for $45,000,000 by Compass, 7983 E. Boulevard Drive in Alexandria will be 18,000 square feet on 10 acres. There are few chances to own 10 acres on the scarce residential waterfront property that lies between Old Town Alexandria and George Washington’s Mount Vernon.  Making it even more special is that this property was once owned by George Washington as part of his 1,800-acre River Farm, the northernmost of the five farms that comprised his sprawling 18th-century estate.


RiverGate on the Potomac has been designed by the noted Harrison Design Associates Architects and is slated to be built by luxury home builder Horizon Builders.  The property will be a classical waterfront estate that takes advantage of this pastoral tree-lined property as it gently slopes down to the wide 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 homewill include tall 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.
