A SHOWSTOPPER! This stunning, modern craftsman is nationally recognized for its design and construction techniques that meet rigorous standards for hyper energy efficiency. Sitting on a picturesque 18,720sf lot (nearly a 1/2 acre) with private, tree-house views of Donaldson Run Park, the property includes a 2-car garage and is centrally located in one of the most sought-after neighborhoods of North Arlington. Custom designed by Kaplan Thompson and built by MetroGreen, an Arlington Green Home Choice Builder, the team created a space that takes your breath away. As you enter the gracious foyer to see the treasure trove of exquisite details that greet you, you are struck by the realization that you are immersed in the backdrop of light and natural beauty that envelopes the home from the walls of European-styled tilt and turn triple pane windows. Sophisticated and elegant, the crowning achievement is the fact that this is the only fully certified PHIUS+ passive house in Arlington, exceeding LEED standards and performing up to 85-90% better than conventional buildings, up to three times the performance of LEED buildings. The 'like new' condition of the home, surpassing the quality and integrity of most of today's new construction, has special spaces and features incorporated throughout, including but not limited to: post and beam accents, a stunning Antietam Ironworks custom stairwell railing, extensive built-in shelving, custom polished-concrete surfaces, decorative light fixtures, 4" wide plank hardwood floors on all three levels, 10' ceilings on the main level, and cathedral ceilings throughout the entire upper level. The eat-in chef-inspired gourmet kitchen combines all the necessary high-end accoutrements (Wolf, Bosch, SubZero, U-Line) with a walk-in pantry and family breakfast area immersed in the peaceful backdrop of mature trees, with the option to close-off the space from the dining and living areas with a retractable screen when one wants to experiment with messy new recipes. The open flow to the dining and living room, accented by the custom polished concrete gas fireplace, offers an easy space for entertaining inside or head outdoors via the French-doors to the Ipe wood deck for grilling. This main level is completed by a main level family room/library and privately situated, generously sized main level office. As you explore the upper-level bedrooms and bathrooms, you will find many more special features, maximizing the confluence of design and space. From the enchanting loft within an upper-level bedroom, to the daybed-sized window seat framed with views of the stream and woods, to a child sized cubby "playhouse" corner. The primary suite with its soaring ceilings and large windows overlooking the park setting offers a large walk-in closet and sumptuous spa-like bath with a Japanese soaking tub among its amenities. The above grade, full daylight walk-out lower level offers additional spaces to relax or play, including an expansive recreation room with French-doors, guest suite with full bath, direct access to the flat backyard and natural stone hardscaping, separate Workshop and a bicycle storage room for the pedaling enthusiasts. All this, and you are walking distance to Washington Golf and Country Club, Marymount University, and Potomac Overlook Park. With easy access to the area's nationally acclaimed bike path system, you are only 2 stop lights to WDC/Georgetown, and just minutes from the urban oasis of North Arlington's shops and restaurants from Clarendon to Ballston to Rosslyn, plus points beyond via the Metro or major commuter routes. So, when we say truly sophisticated, special, one-of-kind masterpiece - we mean exactly that: you will not find this custom designed and built, architectural and energy-efficient gem with this spectacular backdrop and location anywhere else.
