Cities across the United States are making significant investments in convention center upgrades and expansions to attract larger conferences, trade shows, and business events. From billion-dollar redevelopment projects to sustainability-focused renovations, convention destinations are transforming their facilities to meet the growing demands of global event organizers.
Houston Advances Massive George R. Brown Convention Center Expansion
The George R. Brown Convention Center is moving forward with a major expansion after the city of Houston and Houston First Corporation announced the sale of approximately $1.38 billion in hotel occupancy tax and special revenue bonds. The funding supports the first phase of the ambitious Convention District Transformation Project.
The master plan is designed to reconnect Houston’s East End with downtown while creating a more walkable convention and entertainment district. A major highlight is the 700,000-square-foot expansion called GRB Houston South, scheduled to open in 2028.
The expansion will include two exhibition halls totaling 150,000 square feet, a 50,000-square-foot multipurpose hall with direct access to the new Central Plaza, a 25,000-square-foot atrium flex hall, and 225,000 square feet of contiguous exhibit space. It will also feature the largest ballroom in Texas, ranging from 60,000 to 80,000 square feet, along with retail spaces, restaurants, and a central atrium designed to maximize natural light throughout the facility.
Detroit Adds New Connected Hotel to Huntington Place
Detroit’s Huntington Place is set to gain another connected hotel as part of an ongoing master redevelopment initiative aimed at strengthening downtown connectivity and boosting convention business.
The new property will offer approximately 600 guest rooms, making it the second hotel directly connected to the convention center. It joins the 601-room JW Marriott Water Square, currently under construction and expected to open in 2027.
The project is part of a broader revitalization strategy that includes infrastructure upgrades like the Second Avenue connector, designed to improve accessibility and community engagement. Construction on the new hotel could begin as early as 2027, though the final hotel brand has not yet been selected.
Huntington Place also recently achieved LEED Gold recertification, reflecting Detroit’s continued focus on sustainability. The convention center offers 723,000 square feet of exhibit space and features Michigan’s largest ballroom at 40,000 square feet.
Austin Convention Center Begins Landmark Reconstruction
The Austin Convention Center has officially closed for a complete reconstruction and expansion under the $1.6 billion Unconventional ATX project.
Designed by LMN Architects and Page, the new facility will nearly double rentable event space, growing from 365,000 square feet to 620,000 square feet. Funding will come through hotel occupancy taxes and convention center-generated revenues, with nearly $18 million allocated specifically for public art installations.
The redesigned center emphasizes flexibility, accessibility, and sustainability with open-air terraces, public gathering plazas, seamless indoor-outdoor event spaces, and architecture that maximizes natural light through transparent design elements and sweeping roof structures.
Once completed in late 2028, the venue is expected to reopen in time for Austin’s 2029 spring festival season. Notably, it aims to become the world’s first zero-carbon-certified convention center under the International Living Future Institute certification standards.
U.S. Convention Cities Continue Competitive Growth
These large-scale investments highlight how major U.S. convention destinations are competing to host larger international meetings, exhibitions, and trade shows. By focusing on expansion, sustainability, modern design, and enhanced visitor experiences, cities like Houston, Detroit, and Austin are positioning themselves as leading destinations for the future of business events and conventions.
