Set along one of Capitol Hill’s most iconic blocks, 319 C Street SE is a distinguished two-unit Federal residence where original historic architecture and modern updates are seamlessly aligned.
The home unfolds across four levels, offering over 3,000 square feet of finished living space. Throughout, natural light moves through well-proportioned rooms, original architectural elements have been intentionally preserved, and the layout feels both elegant and exceptionally livable — equally suited for large-scale entertaining and comfortable daily life.

The main floor is designed for elevated entertaining and everyday ease. A traditional foyer with vestibule opens into an elegant living and dining sequence anchored by an original marble fireplace with a marble mantelpiece. The fully updated kitchen features granite countertops with a breakfast bar, top-of-the-line KitchenAid stainless steel appliances, including a gas stove, refrigerator with Sabbath mode, built-in microwave, and solid oak cabinetry offering extensive storage, all overlooking the private fenced garden below. A beautifully finished full bathroom on the main level includes a tiled shower with bench seating and high-end Kohler fixtures.

The entire top floor functions as a true primary level, offering two large bedrooms, each accommodating a king-sized bed, a sunroom ideal as an office or reading room, multiple closets, and a beautifully appointed bathroom. From the bathroom and front bedroom, enjoy year-round views of the iconic Library of Congress and seasonal views of the United States Capitol when the trees open in winter. The primary bath is designed as a true retreat, featuring a deep soaking tub with multiple Moen showerheads, including a handheld sprayer. Two additional generously sized bedrooms, another sunroom, and a full bathroom with a walk-in shower and full-length glass doors occupy the second floor.

The secondary residence is the home’s garden-level English basement, a fully separate studio apartment accessible from inside the primary residence. Offering nearly 600 square feet of finished living space, it has its own vestibule and includes an updated kitchen with full appliances, a full bathroom with heated tile floors, laundry, and direct access to the rear patio and garden. It functions as a true extension of the home — ideal for guests, multigenerational living, au pair accommodations, or income-producing potential.
The rear garden is exceptionally private and increasingly rare for Capitol Hill. Designed for both entertaining and everyday enjoyment, it features a timed irrigation system supporting lush, low-maintenance landscaping along with a covered patio complete with ceiling fan — an ideal setting for summer evenings or quiet mornings outdoors. The front garden is equally polished, framed by mature plantings and easy-to-maintain greenery.

What truly distinguishes the home is how thoughtfully it has been improved and updated. Major infrastructure investments include a 4-year-old multi-zone HVAC system providing precise climate control across all levels, along with dual tankless water heaters that enhance efficiency.
Positioned just moments from Eastern Market, Barracks Row, Capitol South Metro Station, Pennsylvania Avenue, and Lincoln Park, the home delivers the kind of deeply connected lifestyle that defines Capitol Hill at its best. Spend a morning in the Library of Congress reading room, grab coffee at Starbucks, enjoy breakfast at Pete's Diner, or meet friends for dinner and drinks at neighborhood favorites like Belga Café, The Hawk 'n' Dove, and Butterworth's.
