On the Market: A Historic Alexandria Estate That Dates Back to the 1760s

The Southern plantation–style home was moved from Sussex County to Alexandria in the 1940s.

Alexandria is known for its historic homes — and the future owner of 4509 Carlby Ln. in Alexandria will not only love the estate’s historic background, but also its amazing water views.

Built in the 1760s, the Southern plantation–style estate was originally located in Sussex County, Virginia, and owned by Gen. Winfield Scott, who served in the War of 1812, Mexican-American War, and Civil War. During the 1940s, retired U.S. Navy captain Carl W. Porter relocated the home to Alexandria along the Potomac River.

Located just 200 feet from the water, the estate sits on more than 2 acres and includes five bedrooms, four bathrooms, and nearly 3,000 square feet. The house is currently listed at $4,999,900.

Original, wide-plank pine floors are featured throughout the first floor. Being a Southern plantation-style home, the Carlby estate’s front and back doors align to allow a cool summer breeze to flow through the home.

The home’s historic features shine in the grand living room. The room boasts 12-foot ceilings, preserved moldings and paneling, nine-over-nine windows, and restored wainscoting and woodwork.

For a more close-knit space, make your way to the den. Along with the detailed fireplace, the room includes a full bathroom, allowing the space to be turned into a first-floor bedroom.

The den leads into the former dining room area. In the formal space, you’ll find a fireplace and a custom chandelier inspired by one found in Gunston Hall. Guests will be able to enjoy dinner with a view as the room overlooks the Potomac River.

Inside the galley kitchen, you’ll find the home’s modern touch. Despite the home being built in the 18th century, you’ll still have access to up-to-date appliances and storage space.

The second level of the home features the expansive owner’s suite with an en-suite bathroom. This room spans the full width of the home, allowing you to take in the picturesque views of the entire property. The rest of the level includes two additional bedrooms, a full bath, and custom built-in closets.

You’ll feel like you’re at George Washington’s Mount Vernon estate — which is located just down the road — when you walk onto the portico. The backyard includes 151 feet of water frontage and access to your own pier on the Potomac.

The property also includes a detached double garage with storage, a historic smokehouse, and a shed.

The home at 4509 Carlby Ln., Alexandria is listed by Andrea Courduvelis and Diane Murphy at TTR Sotheby’s International Realty.
