In the heart of the historic Spring Valley neighborhood stands 4827 Sedgwick Street NW, a classic 1948 Colonial set on a quiet, tree-lined street. What started as a shell has now been transformed into a modern, sophisticated new construction home that spans nearly 5,000 square feet on 4 levels. The refined reimagining is the work of Kent Construction & Development and renowned designer Lisa Najafi, names synonymous with quality craftsmanship and design integrity. A wide flagstone walkway leads to the warm and inviting facade, finished in a soft creme palette and accented with moss green shutters. Inside, there's meticulous attention to every detail-wide plank white oak floors, solid core wood doors, generous crown moldings and door casings, designer lighting, and super luxe finishes from Waterworks, Baldwin, Restoration Hardware and Rejuvenation. Thoughtfully designed, the formal living room features a wood-burning fireplace with a restored mantel and Italian marble. The dining room offers a dramatic lighting fixture and a large picture window that floods the space with natural light. The adjacent office steps down to the rear lawn, offering seamless indoor-outdoor living. The chef's kitchen is a culinary delight featuring custom beaded inset cabinetry with European hinges, natural stone backsplash with pot filler, and a stunning white oak island topped with a large 10-foot double-thickness Quartzite countertop imported from Brazil, ideal for entertaining. The appliances are equally impressive-Wolf eight-burner gas range with double ovens, Subzero refrigerator with hidden fridge cabinet, two three-drawer Viking dishwashers and a Wolf microwave drawer. The adjoining breakfast room features a custom walnut slatted wall detail and wood-burning fireplace with granite imported from India, perfect for relaxed gatherings. A large powder room showcases an Italian marble vanity, designer wallpaper and elegant sconces. Upstairs, the primary suite offers a serene retreat. The closet features custom cabinetry, dimmable integrated lighting, velvet-lined jewelry drawers, shoe racks and valet rods. The spa-like primary bath is outfitted in marble from top to bottom and features radiant heated floors, James Martin vanity with double sinks, a floating tub, and a walk-in glass shower with dual rain shower heads. Three additional ensuite bedrooms, one with a copper balcony, and a convenient laundry room with a full-size washer and dryer complete this level. The expansive top floor offers an abundance of flex space-ideal for a rec room, a game room, an additional bedroom or a second office. Plus, there's lots of great storage. Downstairs, the space is designed for entertaining, lounging and exercising. The family media room features a wood-burning fireplace, custom walnut wall detail, fluted media cabinet, 75-inch TV with surround sound system, high-end electronics and built-in shoe cubbies and coat hooks. There's also a dedicated gym with rubber flooring and floor-to-ceiling mirrors, an additional laundry room and a fifth ensuite bedroom. A single-car garage with security camera and remote entry complete this level. Behind the scenes, advanced smart home systems include ADT security, video surveillance, energy-efficient Marvin windows, 80-gallon electric water heater and two dual-zone, gas-fired HVAC systems. Out back, the newly fenced backyard features mature landscaping and a flagstone patio that makes for elegant outdoor entertaining. With close proximity to Spring Valley Village, American University, and some of the finest shopping, dining and nightlife in DC, 4827 Sedgwick Street NW not only refines urban living, it redefines it.
