This stunning, quintessential Colonial has been transformed by the sellers, creating a home adaptable to the needs of a modern family. Whether you're working from home, entertaining, or spending quality time together, 300 Mansion Dr has space (and storage!) for everyone. An optimal blend of convenience and seclusion, this corner lot offers buyers an idyllic and contemporary experience in Colonial Park, Alexandria. The quiet front entrance faces Mansion Dr, the corner property on this sought-after street. The proud Colonial boasts symmetrical windows with black shutter decor, allowing natural light to pour into every room. Step inside, the grand foyer mimics the symmetry of the exterior, branching off to the living, dining, and family rooms. The combination of crown and dentil molding throughout the main level is reminiscent of the original 1930s style. Every room in the home is spacious and allows for creative furniture arrangement. The formal living room is no exception, featuring the first of three gas fireplaces with a simple white mantle and marble surround. An office lies beyond the living room, high-ceilinged and with substantial room to create your ideal at-home work space. Congregate around the kitchen, the beautiful cream and sage colors present a soft aesthetic and the radiant heat floors add an extra level of comfort while you prepare dinner. The inviting island with second sink and casual breakfast bar seating is made for sous chefs with little hands and friends with new stories. Multi-colored granite counters provide ample space to cook, while the cabinet storage on three walls ensures you'll always stock the right ingredients. Stainless steel appliances, including a gas cooktop above the flush wall oven and a double-door beverage chiller, are placed thoughtfully to create a functional and convenient kitchen. Let the party easily flow to the family room, western exposure from the wall of windows keeps the room bright throughout the day. A large sectional to fit the whole family sits comfortably in the space, with room to spread out during Marvel movie marathons. Another gas fireplace amplifies the cozy atmosphere. Slate flooring transitions into a wainscoting-like border on the sunroom walls, and encompasses the third gas fireplace, warming guests in the winter. 2021 fans drop down from the vaulted ceiling to circulate air in the summer. Four bedrooms and three full baths occupy the upper level. All baths were updated in 2020. The primary suite, heightened by tall ceilings and skylights, exudes peace and tranquility. The primary bath features radiant heat flooring, to keep your feet warm stepping out of the shower or separate soaking tub. Double sinks encased with quartz counters, and multiple closets are the cherry on top of this relaxing suite. Two of the beds share a hall bath, while the fourth bedroom is the ideal guest retreat - an attached bath with marble counter gives your visitors privacy during their stay. The lower level, renovated this year, features a rec room and utility storage space, plus a convenient half bath. Egress windows let in additional light, illuminating the basement. This property is situated to maximize privacy. Landscaped evergreens stand tall, lining three sides of the yard on Russell Road, creating a sanctuary to host birthday parties on the expansive stone patio and games of "fetch" in the grassy play area. The front and garage entrances are tucked away on the opposite side of the home, the one-car garage provides additional storage and sheltered access straight into the kitchen from your car. Discuss the latest with friendly neighbors while enjoying "strolling cocktails" up the street. Positioned between Braddock Rd and Mount Vernon Ave, this home is walking distance to several local schools and dining and shopping options in Del Ray. Catch the Metro bus line on Russell Rd to Braddock or King St stations, making your morning commute a breeze.
