Just minutes from Potomac Village, Bethesda, Washington, DC, Northern Virginia, and major commuter routes, the home offers the perfect balance of privacy and convenience. Designed with quality craftsmanship and timeless architecture, the residence showcases impressive room sizes, soaring ceilings, extensive decorative millwork, hardwood floors, custom built-ins, and a dramatic two-story marble foyer.

The walk-out lower level is designed for entertaining with a recreation room, fireplace, full bar, second kitchen, wine cellar, fitness or game room, additional bedroom, and full bath. The park-like grounds are equally impressive, with a picturesque creek, charming footbridge, mature landscaping, and exceptional outdoor living spaces that create a peaceful estate setting. A remarkable combination of location, quality construction, generous living spaces, and exceptional flexibility makes this one of Potomac's most compelling luxury offerings. ***Features***Whole House Generator***Two Gas HWH 2016, 2019***Two Zone Gas Furnace 2015, 2016***Two Zone AC 2013, 2015***Roof 2004***Irrigation System***View Virtual Tour for Video***
