Open House Saturday 1:00 - 3:00pm Welcome to 3901 Colonel Ellis Avenue, a rare opportunity to own an expanded 2-car garage colonial on a flat lot in the highly sought-after Seminary Ridge community. Offering 4 bedrooms, 2.5 baths, and nearly 3,000 finished square feet above grade (and 1,000+ sq ft in the unfinished basement) , this spacious home combines generous living areas, thoughtful updates, and timeless appeal in one of Alexandria's most desirable neighborhoods. Recent improvements include newly installed and refinished solid oak hardwood floors throughout the main level, fresh paint throughout the interior, new light switches and outlets throughout the home, and new exterior shutters that enhance the home's classic curb appeal. Step in from the covered front entry and discover an ideal balance of formal and casual living spaces that create a home equally suited for everyday living and entertaining. A sunlit formal living room welcomes guests, while the impressive dining room, expanded by a thoughtfully designed rear addition, spans approximately 24 feet and is perfect for holiday gatherings and entertaining on any scale. The rear addition transformed the heart of the home, creating an expansive kitchen with an island, peninsula seating, abundant cabinetry, and generous prep space that is open to a casual dining area and an adjoining family room, providing the perfect setting for everyday living and entertaining. The vaulted ceiling and abundant natural light add to the open feel. Adding even more flexibility, a separate family room with a wood-burning fireplace and wet bar offers an inviting retreat that can also serve as a home office, media room, playroom, or additional gathering space. Upstairs, you'll find four generously sized bedrooms and two full baths, including a spacious primary suite with dual vanities and ample room to customize the closet space to your needs. One secondary bedroom features direct access to the hall bath, offering "princess suite" functionality while also providing the opportunity to create a future third full bath and upper-level laundry room. The expansive 1,044-square-foot unfinished lower level offers excellent ceiling height. Whether you envision a recreation room, guest suite, home gym, or additional storage, the lower level provides exceptional flexibility and could bring the home's total finished living space to nearly 4,000 square feet. Outside, the fenced, mostly flat backyard is a rare find in Seminary Ridge, offering plenty of room for play, entertaining, gardening, or future outdoor living spaces. The attached two-car garage, along with a driveway accommodating two additional vehicles, provides ample off-street parking. Tucked just off Seminary Road, Seminary Ridge is a peaceful enclave of stately homes known for its quiet streets, strong sense of community, and exceptional convenience. The neighborhood's underground utilities and sidewalks enhance both its beauty and walkability. Residents enjoy quick access to I-395 and the Express Lanes to downtown DC, along with proximity to top public and private schools including St. Stephen's & St. Agnes, Episcopal High School, Bishop Ireton, MacArthur Elementary, and Alexandria City High School. Shopping, dining, grocery stores, fitness studios, parks, and historic Old Town Alexandria are all just minutes away. Offering generous living space today with the opportunity to create nearly 4,000 finished square feet, this is an exceptional opportunity to personalize a home with outstanding bones in one of Alexandria's most sought-after neighborhoods. Priced below market in a community where updated homes exceed $1.6 million, 3901 Colonel Ellis Avenue delivers an outstanding combination of space, flexibility, location, and value.
