Completely renovated in 2023 | This one-of-a-kind Colonial in the heart of idyllic Crestwood features a brand-new, two-level Accessory Dwelling Unit (ADU) at the rear of the property. The separate 1,000 sq. ft. carriage house includes 1 bedroom, 1 full bath, a full kitchen, and a laundry room. While the main listing reflects only the primary residence, this home actually includes 6 bedrooms, 5.5 baths, and over 5,500 total square feet of living space when factoring in the separate 1,000 sq. ft. ADU. The two-level carriage house provides unmatched flexibility, whether for rental income, an au pair suite, extended family, a guest house, or an Airbnb opportunity. The upper level features a spacious bedroom and full bath, while the main level boasts a large open-concept living area with a full kitchen, in-unit washer/dryer, and abundant natural light--a rare find in D.C.'s housing market. The main home is equally impressive, offering a bright and open first floor with a gourmet kitchen featuring an island, a spacious dining area, and a cozy living room with a fireplace. A wall-to-wall glass door opens to a covered patio overlooking the beautifully landscaped backyard--perfect for entertaining. A convenient half bath completes this level. Upstairs, the primary suite boasts a walk-in closet, three additional closets, and a spa-like bath with a double vanity. Two additional bedrooms share a stylish full bath in the hallway. The third level features a versatile suite with another full bath, a cedar-lined closet, and built-in storage, making it ideal as a bedroom, playroom, or inspiring home office. The lower level includes a spacious recreation room with a fireplace, perfect for a home theater or lounge space, along with a flex room that can serve as a bedroom or office, a full bath, and a large laundry room with backyard access. Parking is effortless with a private multi-car parking area off the rear alley, plus ample street parking out front. Nestled in one of D.C.'s most sought-after neighborhoods, Crestwood is a hidden gem offering quick access to downtown via Rock Creek Parkway and 16th Street, as well as proximity to Rock Creek Park, the Fitzgerald Tennis Center, Carter Barron Amphitheater, and Metro Bus lines just a block away. A short drive west takes you to Van Ness and Cleveland Park, adding even more convenience to this prime location. This is a truly once-in-a-lifetime opportunity to own a home with a completely separate, fully equipped carriage house--something you won't find anywhere else in the city
