D.C.'s Premier Event Spaces
The building's stylish spaces create an extraordinary experience for all types of events.
Located in Chinatown/Penn Quarter, The National Union Building is an elegant, historic building encompassing 6 floors of dedicated event space.
Designed by local architect Glenn Brown and built in 1890, the National Union Building boasts a striking Romanesque, stone clad façade and maintains captivating period details that give it character unlike anything else in D.C.
Soaring ceilings, curved glass, and exposed brick greet guests as they ascend our original wrought-iron staircase or the city’s last remaining central-core elevator cage.

Everything about working with Catering by Seasons, from the planning, communication, to the execution was phenomenal!
The food, of course, was a highlight. Several attendees went out of their way to mention that it was the best they’ve ever had at a corporate event. Your ability to deliver this high-quality experience with such ease made a lasting impression, and we truly appreciate the effort and care that went into making everything perfect. Thank you again for making our event such a success.
Catering By Seasons exceeded my expectation. I used them for a brunch at my house after my son’s bar mitzvah. The level of professionalism along with their responsiveness made me feel at ease right away.
