400 O Street SW 402Washington, DC 20024

A rare offering in the sought-after 400 building—the only unit currently available and a true penthouse residence that elevates both your lifestyle and your investment.

Positioned at the top, this penthouse delivers what buyers are searching for but rarely find: privacy, natural light, and a sense of exclusivity that simply doesn’t exist on lower levels. With no competing inventory in the building, this is a unique chance to secure a premier unit in a tightly held community.

Inside, the home offers a thoughtfully designed layout that maximizes space, light, and functionality—ideal for both everyday living and entertaining. Elevated sightlines and top-floor positioning create a quiet retreat above it all, while still keeping you connected to everything happening around you.

Location is where this property truly shines. Situated in Southwest DC, you’re moments from:

--The Wharf – dining, waterfront views, entertainment, and nightlife
--Navy Yard – home to Nationals Park, parks, and a rapidly growing restaurant scene
--Capitol Riverfront & Audi Field – one of DC’s most active lifestyle corridors
--Easy access to Metro, commuter routes, and downtown DC

This location continues to benefit from ongoing public and private investment, making it not just a place to live—but a smart long-term play. Ai has been used to show the condo as a blank canvas experience.
