Transformation Is On The Horizon
The Cobb-Marietta Coliseum & Exhibit Hall Authority, owner and operator of Cobb Galleria Centre, Georgia’s premier mid-size convention venue for tradeshows, meetings and special events, has assembled an enviable team of Cobb County-based firms to manage the design and construction of the expansion and renovation of Cobb Galleria Centre. This transformative project is scheduled to break ground in fall of 2025 and be completed in early 2027.
The current project master plan scope includes:
- Demolition of Galleria Specialty Shops and 2nd floor meeting rooms;
- Creating an exciting new, 2-story grand entryway, a new junior ballroom to complement the existing John. A Williams ballroom, two unique outdoor event courtyards and gardens with natural lighting penetrating interior conference room spaces, and new connected parking with covered, all-weather access into the expanded facility;
- Addition of 13,000 square feet of state-of-the-art meeting space with enhanced graphics and technology; and
- Extensive renovation and facelift of existing convention space, concourse, rotunda and ballroom.
