Built by Showcase Home Builders, one of Arlington's premier builders, and set on a quiet, tree-lined stretch of Winchester Road, this contemporary new construction pairs the desirable Morningside neighborhood with bold modern design. With 5 bedrooms, 3.5 baths, and 3,463 sq ft across four finished levels, the home features solid oak hardwood floors, designer tilework, oversized windows, and high-end finishes throughout. A wood-slat accent wall and glass-paneled front door set the stage at the entry, opening to a living room anchored by a floor-to-ceiling tiled fireplace with floating oak mantel, flowing into the kitchen and dining area with direct access to the rear deck. The chef's kitchen features a quartz waterfall island with a lit, fluted wood base and ample seating, custom two-tone cabinetry with brass hardware, a custom wood range hood, textured tile backsplash, designer light fixtures, built-in wine cooler and microwave, and professional-grade stainless steel appliances. The adjacent dining area looks out over the backyard and deck through a wall of windows, with al fresco dining just steps away. A first-floor bedroom behind a glass-paneled door works equally well as a home office, and a half bath with floating vanity completes the level. An open staircase with oak treads and glass railing leads upstairs to the spacious primary suite, with a walk-in closet fitted with custom shelving and a spa-inspired bath featuring a floating double vanity, backlit mirror, and tiled shower with dual showerheads. Two additional bedrooms share a tiled bath with double vanity and tub, alongside a dedicated laundry room. The third floor, with vaulted ceilings, adds a lounge with wet bar and wine cooler, a fifth bedroom, and a full bath, providing the perfect space to unwind. The finished lower level includes a mudroom with built-in bench and cubbies, a gym/playroom, and a flex space for a home office, with direct access to the built-in garage. Set on a corner lot, the backyard offers a large, level lawn enclosed by new cedar fencing, a composite deck for dining and entertaining, and a storage shed, with a paver walkway, new landscaping, and a paved driveway out front. Moments from Stratton Elementary, Ottoson Middle, the Minuteman Bike Path, and Route 2, with Arlington Center, Alewife, Cambridge, and Boston all within easy reach.
