Welcome to one of Great Falls' most distinguished estates, gracefully positioned within the highly coveted Riverside Manor community. Set on a rare 1.01-acre lot with public water and located within the prestigious Langley High School pyramid, this exceptional residence offers over 6,000 square feet of refined living space, remarkable privacy, and an enduring sense of timeless elegance. Embodying the coveted old-money aesthetic, the home seamlessly blends classic architectural character with thoughtfully curated modern updates. Extensively expanded and renovated in 2005, the residence reflects a level of craftsmanship and permanence that transcends trends. Rich custom millwork, intricate crown moldings, built-in cabinetry, open floor plan and bespoke architectural details create an atmosphere of understated luxury rarely found in today's newer construction. Designed for both grand entertaining and comfortable everyday living, the home features five spacious bedrooms, five full baths, formal and informal gathering spaces, a magnificent custom library, and a chef's kitchen appointed with premium Wolf appliances, a Sub-Zero refrigerator, dual Miele dishwashers, and a warming drawer. The kitchen opens effortlessly to inviting family spaces that overlook the estate's mature landscaping and resort-inspired outdoor setting. The upper level is anchored by a gracious primary suite offering dual walk-in closets and a beautifully appointed spa-like bath. Three additional bedrooms are complemented by two full baths. For those seeking additional customization, hard-wood flooring preserved beneath the carpeting throughout most of the upper level presents an opportunity to uncover and reveal another classical architectural feature. The walk-out lower level provides exceptional flexibility with a private guest suite, custom bar, billiards area, family room with a wood-burning fireplace, home theater, and direct access to the outdoor terrace. Outside, the estate unfolds into a private sanctuary. A heated gunite pool, expansive manicured lawns, towering mature trees, established gardens, and professionally designed landscaping create a setting that evokes the charm of a legacy property, one that would take decades to replicate. Every element has been thoughtfully curated to capture the essence of timeless estate living. Ideally located just minutes from the Potomac River, Great Falls Park, River Bend Park, Georgetown Pike, Route 7, Tysons, Reston, Dulles International Airport, and Washington, D.C., this extraordinary offering is further enhanced by front and rear irrigation systems, a whole-house generator capable of powering approximately 85% of the residence, and an integrated interior audio system. Rarely does a property combine estate-scale grounds, enduring craftsmanship, modern infrastructure, and a legacy of refined living that never goes out of style.
