About This Home

Welcome to 331 Alastair Street – a well-maintained corner-lot Colonial in the beloved Kettering neighborhood of Upper Marlboro. Kettering is its own gem: tree-lined streets, community pride and an unbeatable location. This 3000+ sq ft home delivers the space and upgrades today's buyers want. The Main level features beautiful hardwood floors throughout, a separate Living and Dining Room, a Powder Room, a remodeled Kitchen with custom Decora cabinetry, quartz countertops, stainless-steel appliances, and direct access to the large fenced-in backyard. The Family Room features a brick fireplace and patio doors opening to the backyard built for real living – with a motorized awning, retractable privacy screens. Rain or shine, you’re covered. The Hardwood floors continue to the stairs and Upper level, where you will find four Bedrooms (all equipped with ceiling fans) and two full baths. The Primary Suite features a walk-in closet system, the en-suite Bathroom is elevated by a luxurious Bain Ultra air tub – for your personal spa. Pull-down attic access adds bonus storage. The Basement offers excellent flexibility with a Laundry Room equipped with a utility sink, a Storage Room with shelving to keep everything neatly tucked away, great for stashing holiday décor and seasonal items, a Gym (or extra Living space), an additional separate Living space, and another powder room. There is also a doorway to the backyard. A 48,000 BTU AC system replaced a few years ago and a whole-house humidifier keeps indoor air comfortable year-round. The Garage has both a Storage system and overhead storage. In addition, the driveway has been widened to allow for extra parking out front. The property also features a professionally installed French Drain system. Location seals the deal – quick access to I-495/95, easy commutes to D.C. and Northern Virginia, and Watkins Regional Park’s 850+ acres just a 15-minute walk away. Kettering Plaza and Woodmore Town Center are nearby for all your everyday needs. The bones. The upgrades. The location. All it needs is you.
