Rarely does a home in North Arlington offer this kind of transformation. Set on 20th Road North in the heart of the coveted 22207 corridor, this residence was nearly doubled in above-ground square footage through a sweeping 2024/2025 rear addition that delivered an entirely new kitchen, open living room, mudroom, walk-in pantry and primary suite, all unified by solid white oak hardwood floors and Marvin black-frame windows throughout. The kitchen is the centerpiece of the addition: floor-to-ceiling navy shaker cabinetry, white quartz countertops, a stainless farmhouse sink, KitchenAid induction range with stainless hood, elongated subway tile backsplash, and a substantial oak island with seating for four beneath a trio of brass pendant lights. A dedicated mudroom and oversized walk-in pantry flank the kitchen, delivering the kind of daily organization rarely found at this scale. The new open living room flows directly off the kitchen and opens to the backyard through a full-width Marvin sliding glass door, creating seamless indoor-outdoor living. The primary suite is entirely new and unmistakably considered. The bedroom features a painted brick accent wall and a custom walk-in closet with built-in shelving, pull-out shoe racks, and dual hanging sections. The primary bath delivers handmade terracotta hexagon tile floors, square tile shower with dual rain shower heads, matte black fixtures, a glass enclosure, and a fluted oak double vanity topped with Calacatta-veined quartz countertops. Additional 2nd and 3rd bedrooms are well-proportioned, each bright with Marvin windows and white oak floors. The renovated secondary bath (2023) features brass fixtures and a crisp white vanity. The fourth room is on the main level and can be used as an office or flex space. The renovated basement with custom built-in storage (2023) and new paver driveway rounds out the home's updated footprint. Infrastructure is equally considered: a new heat pump serves the upper zone, a Carrier Infinity high-efficiency system handles the lower level, and a Navien tankless water heater delivers on-demand hot water. GE Profile washer and dryer are included. New roofs on both the original structure (2022) and addition (2025/2026). No HOA. Also, the house is wired for an EV charger. Set in one of Arlington's most walkable and sought-after neighborhoods, minutes from the District and steps from the best of North Arlington's dining and retail, this property represents a rare opportunity to own a home that performs like new construction in the heart of 22207.
