With 12 versatile event spaces spread across six floors—including a speakeasy-style cocktail club and modern meeting rooms with full AV support—this venue is purpose-built to accommodate everything from intimate gatherings to large-scale conferences, receptions, and activations.

A Venue With Purpose—and Personality

The National Union Building isn’t just another rental space—it’s a place designed with planners in mind. The venue’s design pays close attention to detail, offering atmospheric architecture, seamless guest flow between rooms, and tech-forward amenities that make event execution smooth and stress-free. Exposed brick, high ceilings, tin detailing, and natural light give each floor its own unique energy, allowing you to choose a backdrop that enhances your brand, gathering, or celebration.

Whether you’re planning a corporate off-site, non-profit fundraiser, thought leadership summit, product launch, or private social event, this is the kind of venue that flexes to meet your needs.

A Closer Look at the Spaces

Each of the 12 spaces at National Union Building offers something distinct. Here's how planners can maximize their event experience:

The First & Second Floors: Stylish Yet Intimate

• First Floor North: With a rustic black tin ceiling, brick walls, and cozy lighting, this space creates an inviting lounge vibe—ideal for cocktail receptions, meetups, or pre-event gatherings. Pair it with the Second Floor North for a two-level event that offers guests multiple experiences in one.
  
• Second Floor South: Outfitted with a built-in projector and screen, this exposed-brick space is perfect for breakout sessions, workshops, and small group presentations. It can be combined with the north room for a more expansive layout.

Third & Fourth Floors: Smart Meetings + Warm Design

• Taste of DC Demo Kitchen: This interactive space is perfect for culinary classes, team-building activities, or hybrid events with a food focus. Think “Chef’s Table” meets hands-on brand experience.
  
• Fourth Floor North & South: Elegant and tech-equipped, these rooms feature dual ceiling-hung projectors, built-in butler’s pantries, and city-facing windows that add light and character. Combine both for full-floor exclusivity with event flexibility.

Fifth & Sixth Floors: Private, Polished, and High-Capacity

• Fifth Floor Conference Room: Overlooking Penn Quarter, this refined space includes three adjacent breakout rooms—ideal for corporate retreats, board meetings, and high-focus sessions.
  
• Sixth Floor North & South: Vaulted ceilings, exposed beams, wood flooring, and large windows create an airy, dramatic environment. These top-floor rooms are a favorite for upscale receptions, fashion events, and formal celebrations.

The Cocktail Club: A Hidden Gem Below

Tucked away beneath the main building, the Cocktail Club offers a speakeasy-style experience with arched brickwork, a black granite bar, and a spiral staircase connecting to the first floor. This exclusive, 40-person space is perfect for tastings, private parties, and after-hours receptions with a distinctly Prohibition-era flair.
