The Flexibility to Make the Space Yours
Your event shouldn’t have to conform to a one-size-fits-all venue.
With configurations ranging from approximately 30,000 to 120,000 square feet, DEC allows organizers to select a footprint based on the size and needs of their event.
Start with the space you need today, expand as your event grows, or use multiple levels to create distinct experiences within a single venue.

Built for the Realities of Event Operations
A venue has to work before the doors ever open.
DEC was developed with the practical needs of event organizers, exhibitors and production teams in mind—from loading and move-in to show operations and move-out.
Loading access, freight movement, event-floor flexibility, show offices, ticketing locations and supporting building infrastructure help organizers build an operational plan around their event.

A Northern Virginia Destination
DEC is located at Dulles Town Center in Sterling, Virginia, within one of Northern Virginia’s most active commercial corridors.
The location provides convenient access from throughout the Washington metropolitan region, extensive on-site parking and proximity to hotels, restaurants, shopping and services.

Infrastructure for Modern Events
Today’s events depend on reliable connectivity, power and operational support.
DEC provides the infrastructure and available services to support exhibitor requirements, registration, point-of-sale systems, production, attendee connectivity and other event needs.

Your Event Is the Priority
From initial planning through move-out, the DEC team works with organizers to understand the operational requirements of each event and coordinate the venue, services and event plan accordingly.
Our goal is straightforward: provide the space, support and flexibility organizers need to run a successful event.
I would avoid saying things like “white-glove service” or “world-class team.” This feels more credible.
