Down a tree lined private lane off Old Dominion Drive just past Bellview Rd, you arrive at a gated entrance to this magnificent 12,000 square foot home nestled on a sprawling 3.8-acre woodland. Ideally located just 4 miles from both downtown McLean and Tysons Corner, this double-winged Jeffersonian all Brick colonial is a masterpiece of design and craftsmanship. The home sits majestically atop the property’s crest which is approached by a sweeping, long driveway adorned with massive oaks, other hardwoods, extensive specimen plantings and hardscapes by Charles Owens ‘of Fine Landscapes. The driveway culminates in a paver circular drive and motor court, offering a grand welcome and plenty of parking, along with a 3-car garage with custom raised-panel entry and garage doors. This home reflects the owners' dedication and passion to recreate the timeless elegance and enduring quality of estates from a time gone by. Specifically over-engineered for structural integrity. The home was scrupulously finished with the finest materials and methods to showcase the extraordinary talents of carefully selected master craftsmen and tradesmen. The brick work is extraordinary with historic, over-sized hand-made brick with unique curved and angle custom shapes and masons’ detailing, setting this home apart. The Vermont black random-width rough-cut slate roof, all copper flashings, gutters, downspouts, and snow guards, as well as true divided-light, high-efficiency windows, add to the home's durability and aesthetic appeal. When you enter though the front 2” think Mahogany door, you will immediately know you have arrived! You will find that the rooms are generously sized with expansive glass offering glorious views and natural lighting. The open floor plan allows for family and entertainment needs. From the elegant entry foyer, one can access the formal parlor and dining rooms, each featuring wood-burning fireplaces with gas lines. The octagonal great room boasts 14-foot window walls, a coffered ceiling, a stone fireplace, and access to a wrap-around Ipe deck. The Brazilian cherry floors are laid with multipiece species hardwood borders and hand-made medallions and detailing. Exquisite and elaborate multipiece millwork is found throughout, including crown moldings in every room, true raised panel wainscoting on the entire first floor, and historic custom mantels. The enormous chef’s kitchen is open to a family room with deck and porch access, creating a perfect space for gatherings with room for multiple chefs. The kitchen features Wood Harbor full-custom solid cherry cabinetry and Decora semi-custom cabinetry elsewhere.
