For Sale

$4,900,000

Smart Buyer Rebate $49,000

This charming estate is located at the end of a private drive on one of Alexandria's most sought-after streets. Featuring 1.37 landscaped acres, this home offers country estate privacy that is easily accessible to Old Town, Washington, DC, and Reagan National Airport.

The 5,119 square foot main residence was designed as a spacious classic farmhouse, where every window frames the gardens and extensive lawns. Reimagined by a builder and gardener for their family, the home’s elegant custom architectural details include high ceilings up to twelve feet, centuries-old heart of pine floors and library built-ins, four fireplaces, seven bathrooms and three primary suites. The large kitchen with family/breakfast area includes two working areas with sinks and a cozy office. A first-floor primary suite has a dressing room, two full baths and walk-in closets. Steps away is a laundry/home keeping room with its own outside entrance.

Several outbuildings are integral parts of the estate’s charm and unique character- a lovely guesthouse adjacent to the in-ground pool area, an oversized two-story garage with attic and four storage bays and a custom imported glasshouse from England. The setting of the property, its privacy and improvements, would make you think it was the Virginia countryside!

The property's grounds feature several gardens, which were showcased during the national Garden Conservancy's 2025 Open Days event. Stately oaks, boxwoods, topiaries, rare conifers, shrubs and a woodland walk ensure year-round interest in the landscape of this legacy property
