Spacious, light-filled, and move-in ready — this North Arlington expanded Colonial offers the rare combination of classic character and modern updates in one of Arlington's most walkable neighborhoods. Originally built in 1955 with a beautifully integrated 3-story addition completed in 2009, the home features gleaming hardwood floors and dentil molding throughout, creating timeless elegance from the moment you walk in. The oversized gourmet kitchen is a chef's dream with a large island, extra prep sink, professional hood with warmer, double wall ovens, upgraded microwave, five-burner cooktop, abundant cabinetry, plus wine cooler, beverage refrigerator, and French door stainless steel refrigerator. Step outside to a beautifully professionally landscaped and hardscaped fenced backyard with patio, lovely plantings, and raised garden bed. The main level flows from a living room with wood-burning fireplace and bay window, to a formal dining room with crown and chair rail molding, a family room/breakfast nook, and a bright sunroom with plantation shutters and dedicated mini-split. A half bath with marble flooring completes the level. Upstairs, four spacious bedrooms include a primary suite with bay window and en suite bath with dual sinks and jetted tub; a skylight brightens the hallway and one secondary bath features a steam shower. The lower level offers a recreation room with built-ins and fireplace, a fifth bedroom, mudroom, garage access, and generous laundry/storage. Don't miss this one — North Arlington homes with this much space, character, and recent updates don't last long. Schedule your showing today!
