Set among the rolling hills of Great Falls, Alderley Manor is an estate on five acres, inspired by European traditions. The grounds evoke the English Cotswolds, where light-stone manors rise above open expanses and long vistas.
The residence was a collaboration between David Cooper of ACG Architects and BOWA Construction, with further enhancements by Hanlon Design Build. Spanning more than 20,000 square feet, the estate showcases exceptional craftsmanship, timeless style, and premier amenities. A pea stone driveway leads to a central flagstone motor court, where imported Cotswold limestone, a slate roof with metal seams, copper gutters, and freshly repainted woodwork set a tone of enduring grandeur. Classic symmetry, steep gables, and towering chimneys create a striking first impression, balanced by warmth. Every exterior window and door is framed in rich mahogany, underscoring the commitment to quality and authenticity.
Inside, reclaimed antique oak floors and hand-finished millwork reflect the same meticulous standards. Formal and informal rooms are proportioned to feel both expansive and inviting. Exquisite moldings, hand-carved details, custom built-ins, and oversized fireplace mantels with marble hearths enrich the interiors. The layout maintains symmetry while allowing a natural, intuitive flow. Top-tier finishes and fixtures support both grand-scale entertaining and daily living.
The main level features elegant formal rooms, including a moody library with deep green built-ins and bold ceiling wallpaper, and a light-filled main gallery connecting the east and west wings. Informal spaces center around the chef’s kitchen with twin islands, furniture-grade cabinetry, a Lacanche range, and artisanal tilework. The adjacent breakfast room, with exposed beams, a stone accent wall, and multiple French doors, opens to the grounds. The west wing is dedicated to the primary suite, with a private garden, sitting room, dual dressing wings, and two luxurious baths. Two offices, including one with a vaulted beamed ceiling, complete the level.
Upstairs, four bedrooms each showcase a unique design sensibility and are served by Lagos Azul limestone baths with Waterworks fixtures. The lower level is designed for leisure and entertaining, with a transverse gallery leading to a professional cinema, climate-controlled wine cellar, and a fitness center with spa bath, steam shower, and cold plunge, plus billiards and art studio spaces. Behind the scenes, commercial-grade systems ensure seamless living, including a self-sustaining well and septic, whole-house generator, Lutron lighting, smart HVAC, and a comprehensive security system.
Outdoors, the gardens are extraordinary. With an investment exceeding eight figures, the landscaping and horticulture reach a world-class standard, creating a tapestry of manicured gardens, mature trees, and seasonal blooms. The setting is fully irrigated and softly illuminated by custom landscape lighting with hundreds of concealed fixtures that bring the property to life after dark. A heated lap pool with a retractable cover, a pergola-covered dining terrace, and a newly installed sports court provide exceptional opportunities for recreation and relaxation. For the automotive enthusiast, a modern farmhouse-style garage offers three bays, two lifts, a mezzanine lounge, and a cigar bar.
While secluded, Alderley Manor is less than a mile from Great Falls Village and minutes from Tysons Corner, the Reston Tech Corridor, and Washington, D.C.
With its rare combination of space, craftsmanship, architectural integrity, and refined amenities, Alderley Manor ranks among the region’s most exceptional private estates.
