Steeped in history yet thoughtfully reimagined for modern living, this exceptional detached residence, originally built in the 1880s, seamlessly blends timeless architecture with sophisticated luxury. Following an extensive renovation and expansion completed between 2022 and 2025, every detail has been meticulously curated to honor the home's historic character while introducing today's finest finishes and amenities. Spanning nearly 3,200 finished square feet, the home offers four to five spacious bedrooms, three full and one half baths, and beautifully proportioned living spaces with soaring ceilings, oversized windows, and an abundance of natural light. The striking rear addition is defined by a dramatic wall of rare floor-to-ceiling black Marvin windows and doors, creating a stunning architectural statement while seamlessly connecting the interior living spaces to the private rear courtyard. The expanded kitchen and family room serve as the heart of the home, thoughtfully designed for both everyday living and effortless entertaining. The chef's kitchen showcases custom inset cabinetry, Honed Danby marble countertops and full-height backsplash, herringbone hardwood flooring, high-end hardware and fixtures, and a premium suite of Wolf and Sub-Zero appliances, including a paneled refrigerator and dishwasher, built-in espresso/coffee maker, and wine refrigerator. The thoughtfully designed addition introduced a versatile upper-level bedroom or second family room, further enhancing the home's adaptable floor plan. The upper levels offer exceptional flexibility, with the ability to create multiple bedroom configurations, including two distinct primary suite options, private offices, or additional living spaces. Front and rear staircases provide seamless access between the main and upper levels, while a convenient bedroom-level laundry room further enhances the home's thoughtful design and everyday livability. Throughout the residence, refined finishes and bespoke details elevate every space. Original hardwood floors have been beautifully refinished, complemented by new hardwood flooring, elegant millwork and built-in cabinetry, designer lighting and wallpaper, a timeless Benjamin Moore neutral paint palette, plantation shutters, and fully renovated bathrooms appointed with designer finishes. Modern conveniences, including new custom-crafted interior doors with crystal "Old Town" knobs and custom-built front and side entry doors, have been seamlessly integrated while preserving the home’s historic integrity. Outside, the private rear courtyard has been transformed into a tranquil outdoor retreat featuring full-color flagstone hardscaping, automatic landscape lighting, and discreet built-in storage. A rare private alleyway and side entrance further enhance both privacy and convenience, while an additional 500 square feet of basement storage with both interior and exterior access provides exceptional functionality. In addition to the improvements and renovations throughout, all major systems have been updated. Perfectly positioned in the heart of Old Town Alexandria, 220 S.
