Welcome to 9830 Faust Drive in Vienna's Wolftrap Meadows. This beautiful traditional Colonial is nestled on a pristine one-acre lot backing to a lush conservation area, offering a rare level of privacy and tranquility. Designed for both entertaining and comfort, the main level features hardwoods, custom plantation shutters, and a seamless flow. A unique billiards room sits off the foyer, leading to a formal dining area with French doors opening to the deck. The chef's kitchen, anchored by an enormous granite island, truly defines open-concept living, flowing effortlessly into a soaring two-story family room centered by a magnificent stone floor-to-ceiling fireplace facade and bright skylights. The true highlight of this home is the expansive, climate-controlled four-season sunroom. Accessed via French doors from both the kitchen and family room for a seamless transition, this spectacular addition dramatically increases the main-level living space. The sunroom's flexible footprint easily accommodates multiple social layouts-including distinct dining, lounging, and conversation areas-all set against a panoramic wooded backdrop. The second story features a primary suite and two additional spacious bedrooms. The versatile loft/flex space overlooks the family room below; currently used as a home office, it offers the footprint and walk-in closet to be easily enclosed for a private fourth upper-level bedroom. The bright, walk-out basement includes a recreation room, guest bedroom, full bath, and large laundry room. Step outside to the large brick patio to enjoy breathtaking views of the sprawling lot. Additional highlights include its prime location within the desirable Westbriar, Kilmer, and Marshall school pyramid and its proximity to the Fairfax County Cross County Trail, which seamlessly connects to the W&OD trails for outdoor enthusiasts. This home offers the perfect balance of seclusion and convenience with quick access to the Dulles Toll Road, Leesburg Pike, and Rt 123.
