Tucked along a quiet residential street in Arlington’s historic Maywood neighborhood, 3421 21st Avenue North is the quintessential representation of classic Americana suburbia, thoughtfully renovated to blend early-20th-century character with modern craftsmanship. Originally built as a Sears kit home, the residence carries a piece of the country’s architectural history while offering a completely refreshed interior following a comprehensive 2024 renovation by Matt Lee of Lee Design Studio and Arjay West of BOWA, as prominently featured in Arlington Magazine. Positioned on a generous 9,931-square-foot corner lot, the property offers both privacy and flexibility, with room for future expansion while maintaining its charming neighborhood presence.Mature trees and the home’s classic brick construction — a notably rare feature among Sears kit homes — frame the symmetrical facade and create a warm, enduring sense of arrival. Inside, the renovation carefully preserved the home’s character while introducing warm, custom finishes throughout. Extensive trim and millwork has been exactingly installed to complement the red oak flooring, while Waldorf crystal glass knobs and glass entry doors from Emtek’s fitting Old Town collection serve as curated accent pieces.Vaulted ceilings, exposed brick walls, and cedar beams in the main living space create an ethereal sensation of depth. The centerpiece is a stunning custom limestone and concrete fireplace mantel by Artisan Kraft, while an ambient glow emanates overhead from LED lighting embedded within the ceiling beams. Likewise, another highlight is the den, complete with built-in cabinetry, a wet bar with a unique American Tin Ceiling copper backsplash and hammered copper sink, as well as a spectacular 250-bottle wine cellar complete with custom shelving.A spiral staircase with oak treads and a copper railing serves as a striking architectural focal point, connecting the main level to a lofted home office above.The kitchen pairs modern functionality with timeless materials. Quartz countertops anchor the island, while granite counters and backsplash line the perimeter. Merillat cabinetry with dovetail construction and soft-close drawers provides an elevated, ample storage solution, complemented by a GE Profile Monogram appliance suite including a dedicated wine refrigerator. A 36-inch dual-fuel professional range — featuring a gas cooktop paired with an electric oven — offers the best of both worlds and is especially favored by chefs for its precision and consistency.Accommodations comprise three bedrooms with ClosetZone storage systems. The primary bath evokes an old-world charm with its vintage tilework while introducing modern comforts by way of Brizo fixtures and radiant heated floors. The lower level bathroom features the same amenities and showcases Restoration Hardware and Delta fixtures, as well as a distinctive Thaine black and copper pedestal bathtub.Having gone beyond skin-deep, the renovation upgraded numerous mechanical, structural, and technological systems to exceed contemporary lifestyle demands. Double-pane Jeld-Wen windows and doors, a stylish detached, heated two-car garage with EV charging, SimpliSafe security, and advanced HVAC complete the list of amenities.Located near neighborhood parks, dining, and everyday conveniences, the home also is proximate to major commuter routes into the city. With its blend of historic roots, custom craftsmanship, and modern updates, 3421 21st Avenue North presents a rare opportunity to own a thoughtfully restored home in one of Arlington’s most charming neighborhoods.
