Welcome to this extended Berkley model, featuring a three-level extension, in the highly sought-after McLean Hundred Community, with top ranked schools and a centrally located 4-acre park. This beautiful property, set back from the road, has the only tree-lined drive in the neighborhood. A quiet, private oasis in the suburbs, it is located just outside the beltway close to Tysons, the Silver Line Metro, and the Dulles Toll Road. The location boasts an easy commute to Dulles International Airport and the Tech Corridor. Also close by are parks, recreation centers, and sports fields.  Entering the home brings you into the grand two-story foyer on the main level. Continuing throughout this level, you will find such features as hardwood floors, a private office with French doors, and a formal living room which flows into the dining room. The dining room is perfectly situated next to the high-end kitchen with brand new appliances, brand new quartz countertops, and breakfast area, which flows both into the bright, window-lined sunroom, and step-down family room with masonry fireplace and back staircase to the upper level. Additional features on the main level are a powder room and laundry/mudroom with utility sink. The theme of the main is bright, spacious coziness, and brings an instant sense of being at home.  The upper level features a redesigned master retreat, complete with hardwood floors, walk-in closet (9x12!!) master bathroom with linen and water closets, and sitting room with three additional closets. Both the bedroom and sitting room have tray ceilings, emphasizing the many luxurious details throughout the home. The remaining three bedrooms also have hardwood floors, and each brings its own charm. The second bedroom has a lovely view of the tree-lined drive, and the third bedroom has a deep walk-in closet (and shares a full hall bath with dual vanities with the second bedroom). The fourth bedroom, which is located a few steps down from the rest of the upper level, has an ensuite bath and two closets. Perfect privacy for guests. Outside this potential guest suite is the top of the back staircase and a hallway overlooking the family room, which allows for an open feeling among those present. The lower level, which contains over 2,000 square feet, adds a whole other dimension of living space. The large recreation area has many possibilities for use, limited only by one s creativity. There is a large exercise room, a den with beautiful built-ins, a full bathroom, and a 512 square foot storage room. This home also has a three-car garage with three separate doors, a composite deck off the breakfast room with which to enjoy the surrounding nature, and an amazing flat side-yard for any kind of outdoor game or activity you can imagine.
