Set among the rolling hills of Great Falls, Alderley Manor is a five-acre estate inspired by the architecture and landscapes of 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 combines architectural integrity, exceptional craftsmanship, and highly considered amenities on a remarkable scale.
A pea stone driveway winds through the grounds to a central flagstone motor court, introducing a residence defined by imported Cotswold limestone, a slate roof with metal seams, copper gutters, and finely finished woodwork. Classic symmetry, steep gables, and towering chimneys establish its distinctly English character, while rich mahogany frames every exterior window and door. Inside, reclaimed antique oak floors, hand-finished millwork, exquisite moldings, hand-carved details, custom built-ins, and oversized fireplace mantels with marble hearths carry the same level of craftsmanship throughout. Formal and informal rooms are generously proportioned yet inviting, with a layout that maintains symmetry while allowing for a natural flow between spaces.
The main level is organized around a light-filled gallery connecting the east and west wings. Formal rooms include a moody library with deep green built-ins and bold ceiling wallpaper, while the informal spaces center around the chef's kitchen, appointed with twin islands, furniture-grade cabinetry, a Lacanche range, and artisanal tilework. The adjacent breakfast room features exposed beams, a stone accent wall, and multiple French doors opening to the grounds. The west wing is devoted to the primary suite, comprising 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 have a distinct design sensibility and are served by Lagos Azul limestone baths with Waterworks fixtures. The lower level extends the home's entertaining and wellness spaces, with a transverse gallery leading to a professional cinema, climate-controlled wine cellar, and fitness center with spa bath, steam shower, and cold plunge. Billiards and art studio spaces provide additional areas for recreation and creative pursuits.
The estate's infrastructure is equally considered. Commercial-grade systems include a self-sustaining well and septic system, whole-house generator, Lutron lighting, smart HVAC, and comprehensive security, providing seamless operation and independence commensurate with the scale of the property.
Outside, the gardens are a defining element of Alderley Manor. An investment exceeding eight figures in landscaping and horticulture has created a highly composed landscape of manicured gardens, mature trees, and seasonal blooms. The grounds are fully irrigated and softly illuminated by custom landscape lighting, with hundreds of concealed fixtures bringing the property to life after dark. A heated lap pool with retractable cover, pergola-covered dining terrace, and newly installed sports court provide spaces for recreation, entertaining, and relaxation.
For the automotive enthusiast, a modern farmhouse-style garage offers three bays, two lifts, a mezzanine lounge, and cigar bar. Despite its privacy, 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 scale, architectural integrity, craftsmanship, infrastructure, and landscape, Alderley Manor stands among the region's most distinguished private estates.
