Steeped in American history and positioned in one of Northern Virginia's most strategically valuable corridors, this rare land assemblage presents a monumental development opportunity. Offered exclusively as a combined package, 5400 and 5408 Mount Vernon Memorial Highway deliver approximately 2.83 contiguous acres of prime, high visibility Alexandria real estate. Located on land originally surveyed and owned by George Washington as part of his historic Mount Vernon Estate, this premier parcel grouping combines two distinct tax identification numbers to unlock a premier footprint for an ambitious builder, investor, or visionary looking to construct a private multiacre custom enclave. The layout of the development portfolio includes 5400 Mount Vernon Memorial Highway, which spans an expansive 1.7 acres and features a stately, sun drenched six bedroom, four and a half bath estate. This structure provides strong immediate rental income or an elegant primary residence while development plans are finalized, offering robust subdivision possibilities. Adjoining it is 5408 Mount Vernon Memorial Highway, consisting of approximately 1.13 acres. The existing cottage serves as a functional teardown, shifting the primary value to its superb, cleared acreage and expansive footprint. By bundling these adjoining properties, developers can bypass the friction of separate land acquisition, optimizing site layout, minimizing setback limitations, and maximizing total lot yield. Together, these properties, encompassing two parcels (Tax ID#s 109-2-01-0035 & 109-2-01-0034) are offered as a combined sale. Beyond its historical pedigree, the location offers exceptional lifestyle and commuting advantages, providing seamless access to major employment hubs, commercial centers, and transit infrastructure. Positioned minutes from Fort Belvoir, it offers effortless access for defense contractors and military personnel. Direct proximity to the George Washington Memorial Parkway, Route 1, and Interstate 95 ensures a smooth commute to the Pentagon, Joint Base Andrews, and downtown Washington, D.C. Residents will enjoy a high quality of life with immediate access to nearby Mount Vernon Plaza and local boutiques, providing a blend of national retailers and local specialties. Furthermore, the property is located just a short distance from the historic waterfront dining of Old Town Alexandria, vibrant eateries, local marinas, and the scenic Mount Vernon Trail, combining suburban privacy with an active lifestyle. This land assemblage represents a significant opportunity along a prestigious corridor, allowing developers to secure a substantial piece of Northern Virginia's heritage and shape its future.
