An Event Venue for your D.C. Vision

When we founded the National Union Building as a DC event venue we had a vision: A gorgeous boutique conference center that could let groups of 50 to 500 people gather to drive discussion, policy, and commerce.

Our clients have hosted hundreds of events to move our country forward and make a better world. They've successfully hosted private events featuring CEOs of Fortune 100 companies, Governors, Senators, Members of Congress, and entertainment leaders. We're just here to make it easy.

Event Space for All Occassions

In addition to conference center offsites and policy events, the National Union Building is a perfect location to host a broad range of your private events.

Location & Transportation

Positioned perfectly between the Hill and the Financial District, we are two blocks away from both Metro Center and Chinatown, connecting us directly to every metro line in the DMV. A stone's throw from the White House and The Mall, your guests will find getting to and from our venue simple, easy, and convenient.
