About This Home

A rare offering in one of Potomac’s most coveted close-in locations, this extraordinary estate is gracefully set on nearly 2.5 acres of breathtaking, park-like grounds. Beyond brick pillars and a sweeping circular drive, the residence unfolds as a private sanctuary—where timeless architecture, exceptional craftsmanship, and natural beauty converge. A gentle creek meanders through the property, crossed by a charming footbridge, evoking the tranquility of a country estate while remaining just moments from the charm and convenience of Potomac Village.
Encompassing almost 10,000 square feet of refined living space, the home has been thoughtfully designed to accommodate both grand-scale entertaining and intimate daily living. Elegant proportions and exquisite decorative millwork define the interiors, with crown moldings and custom built-ins lending a sense of enduring sophistication throughout. At the heart of the home, a dramatic two-story marble floor foyer creates a striking first impression and anchors the flowing floor plan.
Formal living and dining rooms offer graceful settings for entertaining, with hardwood floors and a wood-burning fireplace, while the living room is ideally suited for a grand piano. The updated kitchen, featuring a center island and generous breakfast area, opens seamlessly to the coffered-ceiling family room, complete with fireplace and wet bar. Expansive multi-level decks extend the living space outdoors, offering serene views across the lush rear grounds and sparkling creek beyond.
A richly paneled library with French doors and custom cabinetry provides a warm and inviting retreat, complemented by an adjacent office or optional main-level bedroom with a full bath—perfect for guests or multi-generational living. Additional main-level amenities include a powder room, mudroom with laundry, secondary staircase, and access to an oversized three-car garage.
The upper level reveals a gallery overlooking the foyer, an ideal backdrop for art and cherished collections, and features six bedrooms and four beautifully appointed baths. The primary suite is a true private haven, offering a sitting room, wet bar, expansive walk-in closets, and a private balcony overlooking the grounds—perfect for morning coffee or evening repose. The spa-inspired marble bath features a steam shower and jetted tub, creating a resort-like experience at home.
Designed for memorable gatherings, the lower level is an entertainer’s dream, featuring a full bar, expansive recreation room with fireplace, game or fitness room, second kitchen, wine cellar, bedroom, and full bath. Walls of glass invite natural light and open to the patio and landscaped rear yard, seamlessly blending indoor and outdoor living.
Perfectly positioned near Potomac Village, scenic walking or biking path along Falls Road, Great Falls Park, and the C&O Canal, this exceptional estate also offers effortless access to Bethesda, Washington, DC, and Northern Virginia.
This is more than a home—it is a lifestyle of elegance, privacy, and natural beauty, offering a rare opportunity to own a legacy property in the heart of Potomac. ***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***
