Convention Center Expansion

Horizon Glass fabricated and installed the curtain wall and glazing scope for the Colorado Convention Center Expansion, a $233 million vertical expansion of one of the largest convention centers in the United States in downtown Denver. Designed by TVS and delivered design-build by Hensel Phelps for Denver’s Department of Transportation and Infrastructure, the project added roughly 250,000 square feet atop the existing building—anchored by the new 80,000-square-foot Bluebird Ballroom (the largest multifunction ballroom in Colorado, subdividable into 19 rooms), wrap-around pre-function concourse space, and a rooftop terrace with sweeping views of the Rocky Mountains and the Denver skyline. The vertical expansion was executed while the facility remained fully operational, and the team preserved the iconic “”blade”” roof that defines the building’s place on the downtown skyline.

Horizon’s scope encompassed approximately 30,000 square feet of curtain wall and glazing, including the floor-to-ceiling glass that wraps the pre-function concourse and frames the mountain and skyline views central to the expansion’s appeal. Completed in 2024, the expansion elevated the Colorado Convention Center into a top-tier national meetings venue and earned an ENR 2024 Mountain States Best Project award for Sports/Entertainment.
