The National Union Building is one of D.C.'s premier offerings of DC boutique meeting and conference spaces. Supported by dedicated event space staff, our team works in collaboration with your vendors to help you host a perfect meeting.

“I spoke at a conference at this space and was blown-away by it. It looks like no other space I've seen in D.C. (in the best way possible). ”

Location And 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.

Each floor can adapt to match a variety of themes and meeting formats, from boardroom to theatre style or pod layout to u-shape.

Beyond your daytime meeting or conference, National Union Building is also a great venue to host your post-meeting happy hour, seated dinner, networking brunch, or intimate panel discussion.
