Welcome to The Donaldson, a classic Colonial in the heart of Donaldson Run, offering modern updates, an incredible nearly half-acre lot, and over 2,600 square feet of living space just minutes from DC. The first level offers unmatched flexibility, with a spacious entryway, a large living area with a cozy nook perfect for a playroom, gym, or media space, a flex room with brick fireplace, ideal for a guest room or home office, and a fully renovated bathroom. You'll also find a dedicated workshop, laundry room, and access to the attached garage, a rare blend of function and comfort all on one level. Upstairs, the home opens up into a bright living room, dining room, and a well-maintained kitchen that flows seamlessly to the expansive backyard. Step outside to a private stone patio ideal for summer dinners and weekend lounging. An additional second patio above the garage is perfect for grilling or catching sunset views. Whether you're hosting, gardening, or just enjoying the outdoors, this private, fully usable yard is the true showstopper, a rare find in North Arlington. The upper level also features sun-filled primary suite with a beautifully renovated en-suite bath, two additional spacious bedrooms, and a fully updated hall bath. Recent improvements include refinished hardwood floors upstairs, new LVP flooring on the main level, fresh paint throughout, and new lighting fixtures. All of this, just minutes from DC and Clarendon, with the rare bonus of a private, oversized yard in the heart of North Arlington; a combination that's hard to find and even harder to beat.
