About this home
NEW PRICE! Nestled on the highest point of exclusive Mansion Drive—an intimate enclave of just 31 homes—this secluded and private 1.37-acre estate offers a once-in-a-generation opportunity to own one of Alexandria’s most celebrated private gardens. Forty years in the making, the grounds are a breathtaking tapestry of color, texture, and design, with rose gardens, oversized sculpted boxwoods, raised vegetable beds, mature and rare specimen trees, native plants and a sweeping open lawn ideal for grand events. Multiple national and state garden tours have featured this remarkable landscape, including many arranged by the Head Gardener at Mount Vernon Estate. Meticulously maintained, multi-zoned irrigation system ensures its vibrancy year-round.
The garden seamlessly incorporates a serene pool into its landscape, while a fully fenced backyard enhances privacy and security. Within the garden stands a classic Alitex glass conservatory imported from England and wired with electricity—perfect for seed propagation, potting and more.
The main residence is a beautifully crafted 5,119 sq ft home, blending timeless design with modern comfort. A rare main-level primary suite anchors its own private wing and includes dual full bathrooms and dual walk-in closets. Soaring ceilings—up to 12 feet—crown gracious living and entertaining spaces. Covered terraces at both the front and rear of the home invite relaxed outdoor living throughout the seasons.
A charming guest house offers complete privacy for visitors or multi-generational living, featuring a full kitchen, living room, dining area, and bedroom with ensuite bath. Vaulted pine ceilings and a brick fireplace lend a warm, rustic elegance.
A long private drive leads past the main residence to an oversized detached two-car garage. This iconic estate is also just minutes from St. Stephen's and St. Agnes Lower School and Alexandria Country Day School.
This is more than a home—it's a legacy property for the most discerning buyer.
