A rare opportunity to own architect Walter Roberts' iconic award-winning Sundance home in Reston. This contemporary house received the National Passive Solar Homes Award from the Department of Housing and Urban Development (HUD) in 1979 and the Award of Excellence by the Middle Atlantic Region of The American Institute of Architects (AIA) in 1983. The architect and his family lived here as the first owners. This house seamlessly blends nature, design, and modern comfort. This distinctive passive solar residence offers over 3,000 square feet of thoughtfully designed living space where expansive windows and skylights connect inside to the outdoors, while beautiful wood beams and ceilings add warmth and character. A gently descending pathway leads from the detached two-car garage to the front entrance, revealing a tranquil woodland oasis rarely found in such a convenient location. Inside, the hardwood and tile floors flow throughout three finished levels, while walls of glass capture beautiful, wooded views in every season. The stunning great room addition features dramatic vaulted ceilings and access to a wraparound deck overlooking the woodland-an ideal space for entertaining, celebrations, or simply enjoying the serenity of the natural surroundings. The primary suite offers its own fireplace, a dedicated 2nd water heater, a newly upgraded bathroom with a modern touch, and private access to a large, 2nd deck where you may enjoy your morning coffee, afternoon tea or just unwind at day's end. The originally designed greenhouse on the top level has been renovated with new roofs and skylights facing south. The detached garage is complemented by a large room above, providing exceptional flexibility as a home office, studio, gym, workshop, or additional storage. Extensively updated with double-glazed Pella windows, 5 sliding doors, Mitsubishi multi-zone heating and cooling systems, renovated bathrooms, newer skylights, and numerous recent appliance upgrades. All updates were made with the original architectural style intact while allowing future owners to add their own personal touch. Ideally situated in one of Reston's most convenient locations, this home is just a short walk from Sunrise Valley Elementary, the W&OD Trail, and access to premier shopping and dining, with Route 267 only two traffic lights away for an easy commute. A home like no other, this distinctive residence offers the perfect blend of privacy, natural beauty, and convenience while still feeling worlds away from the hustle and bustle. The current owners have taken great pride in this one-of-a-kind home and hope its future owners will make it a cherished dream home of their own.
