The first phase of a $2 billion renovation to the George R. Brown Convention Center in Houston will begin this year. A new building will include additional parking, exhibition space, meeting rooms, and ballrooms. Overseen by Houston First Corp., the city’s destination marketing organization, the plan also includes a new skybridge connecting to the Toyota Center arena, more restaurants and retail venues, and additional green space and sidewalks in the east downtown area. Total additions will result in 2.5 million square feet of convention center space. The first phase is set to be complete by 2028, while the downtown area improvements are expected to span three decades.
