Exquisite Designer-Reimagined Newly Expanded and Renovated Chevy Chase DC Residence. Rarely does a Chevy Chase home combine the timeless character of a 1937 residence with the vision of an award-winning designer and the quality of a newly completed luxury renovation. 2921 Legation Street NW is one of those exceptional opportunities. Completely reimagined, expanded, and nearly doubled in size during a three-year renovation completed in early 2026, this residence offers almost 3,700 sq ft of finished living space on a landscaped 5,276-sq-ft lot. Personally designed and curated by the owner, an award-winning kitchen and bath designer, the home blends classic architecture, craftsmanship, premium materials, and modern comfort. Originally purchased new, it remained in the same family for four generations. The original Chevy Chase brick Colonial character was carefully preserved, oak floors were refinished, 1930s solid 6-panel doors refreshed and figured brass door hardware and crystal knobs were polished and reused. Original Antique 6 by 14’ heart pine floor boards were removed from the attic to become the new kitchen flooring. The home offers five bedrooms, including two primary suites, 4.5 baths, and exceptional flexibility for guests, multigenerational living, adult children, or a nanny. A Signature Designer Concierge Package is included with purchase, providing private post-closing consultations to personalize furnishings and styling. A contractor’s warranty covers the newly constructed addition, gourmet kitchen, and renovated bathrooms. At the heart of the home is a 16' x 16' designer kitchen with a professional 48-inch JennAir Rise six-burner gas range with griddle and double ovens, plus a 48-inch built-in JennAir refrigerator/freezer concealed behind custom cabinetry. A recessed Zephyr ceiling-mounted hood preserves views through four floor-to-ceiling black-stained Pella wood casement windows overlooking the rear gardens. The custom natural-walnut island is topped by a dramatic 6' x 4.2' Calacatta Imperial marble slab, complemented by matching counters and tall backsplashes, solid bronze hardware, designer bin pulls, and a House of Rohl polished-nickel bridge faucet. Black Pella French doors open to a freeform flagstone and antique-brick terrace. The luxurious primary bath features heated Calacatta Chablis marble herringbone floors, a six-foot freestanding soaking tub, twin custom reeded vanities with marble tops, gold-leaf framed mirrors, Hudson Valley sconces, and an expansive marble shower with ceiling rain head, wall shower, handheld spray, and floating marble bench. A premium TOTO Washlet bidet completes the retreat. The original hall bath features Thassos and Dolomite marble with a handcrafted mosaic floor. The vaulted third-floor retreat can serve as a primary suite, executive office, sitting room, au pair or nanny suite, or private guest suite. The finished lower level adds recreation space, a bedroom or fitness room, children’s playroom, and full bath. Laundry plumbing on both the second floor and lower level adds convenience. Major improvements include a new two-zone HVAC system with high-efficiency gas furnace and heat pump, a 100% replaced roof with new 50-year architectural shingles, House of Rohl polished-nickel solid-brass plumbing fixtures, and TOTO turbo-flush toilets. Outside, fieldstone walls, freeform flagstone walkways, mature plantings, and outdoor living spaces create a gracious setting. A detached garage, private rear alley-access parking pad, and guest street parking add convenience. Top-rated Lafayette Elementary School is a half-mile walk, sharing the block with a beautiful park setting and neighborhood tennis courts. Walking distance to St. John’s College High School, Broad Branch Market, Rock Creek Park, Chevy Chase Community Center and Library, neighborhood restaurants, the historic Avalon Theatre, shopping, and convenient access to downtown Washington and Metro.
