Opportunity is Knocking Atop Arlington Ridge! Calling all visionaries, renovators, investors, and builders-here's a rare opportunity in one of Arlington's most distinctive settings. Perched above the street on Arlington Ridge and tucked away on a cul-de-sac, this original family-owned home offers an exceptional combination of location, setting, space, and possibilities. Solidly built in 1951 with brick and masonry construction, this mid-century modern inspired three level Colonial features remarkably generous room sizes, an open contemporary floor plan, and architectural elements that provide an exciting foundation for renovation. Alternatively, the homesite and sought-after Arlington Ridge location offer an intriguing opportunity to explore building anew. Inside, generously proportioned, light-filled living and dining rooms are highlighted by dramatic walls of glass, an exposed brick hearth with wood-burning fireplace, and beautiful pegged hardwood flooring. The spacious eat-in kitchen and flexible floor plan provide plenty of room to customize the home for today's lifestyles. The partially above-grade lower level offers particularly interesting expansion potential, with unusually large windows, good ceiling heights, a convenient walk-up areaway, and an existing basic cinderblock bath-all ready for a creative transformation. The setting is difficult to replicate. Positioned above the street in the established Aurora Hills/Arlington Ridge community, the property enjoys the character and elevation that make Arlington Ridge such a distinctive part of Arlington, while its cul-de-sac setting provides a welcome sense of separation from through traffic. Yet it remains remarkably convenient-just over one mile from both Pentagon City and Crystal City Metro stations and close to restaurants, shopping, Whole Foods, parks, playgrounds, trails, entertainment, and more. Renovate and reimagine the existing home, or explore the possibilities of creating something entirely new on this special homesite. Either way, this is a rare opportunity to bring your vision to an exceptional location. Please note, this is an Estate sale and the property is being sold strictly "AS IS.”
