Located in the heart of Arlington, nine hundred 20th Street South is a rare opportunity to own a truly distinctive home that blends historic character with modern functionality. The original nineteen thirties Sears home has been beautifully preserved, maintaining its charm and craftsmanship, while a thoughtfully designed two thousand nineteen addition seamlessly expands the living space. With over six bedrooms and four and a half bathrooms, this home offers incredible flexibility—especially for large families, multi-generational living, or those in need of a private in-law or guest suite without sacrificing comfort or privacy. What truly sets this property apart is how it lives. Multiple outdoor spaces—including a rooftop deck, welcoming front porch, expansive rear deck, and a private porch off the main suite—create a seamless indoor-outdoor lifestyle that's hard to find this close to the city. The layout allows everyone to have their own space while still feeling connected, making it ideal for families who want room to grow, host, and entertain with ease. Beyond the home itself, the location is exceptional. You are just minutes from everything that makes Arlington so desirable—vibrant dining, shopping, parks, and easy access into Washington. With proximity to hubs like Pentagon City and Crystal City, plus major commuter routes and transit options, this is convenience at its highest level. Properties that offer this combination of character, scale, and location are incredibly rare—this is a home that not only stands out but truly delivers.
