A striking mid-century modern retreat tucked away on a private, wooded .6-acre lot inside the Beltway. Originally designed in 1951 by renowned modernist architect Charles M. Goodman, this distinctive home was later thoughtfully restored and expanded by architect Michael Cook, AIA, whose work preserved Goodman's architectural vision while adapting the home for modern living. Offering 4 bedrooms, 2.5 baths and more than 2,300 square feet, the residence pairs authentic mid-century character with a dramatic contemporary expansion. Walls of glass, including soaring 11-foot windows, fill the open living, dining and kitchen spaces with natural light and create a remarkable connection to the surrounding woods. The kitchen serves as the heart of the home with an expansive 11-foot peninsula, sleek cabinetry, open shelving and abundant built-in storage. The original galley kitchen was cleverly repurposed as a versatile butler's pantry, homework station and buffet area while retaining its original cabinetry. Upstairs, the cantilevered primary suite creates a true treehouse retreat overlooking the wooded landscape, with soaring ceilings, approximately 22 feet of closet space and a beautifully designed bath that allows natural light to flow throughout the space. Brazilian cherry floors bring warmth to the home's clean architectural lines, while the original brick fireplace and preserved entryway provide a direct connection to Goodman's original 1951 design. Outside, decks and patios extend the living space into the private wooded setting, while an attached two-car garage adds everyday convenience. Featured in Washingtonian for its remarkable architectural transformation, this is a rare opportunity to own an authentic Charles Goodman residence that thoughtfully balances important mid-century design, privacy and modern living in an incredibly convenient Alexandria location.
