ATLANTA – 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, announced today it 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.
Rule Joy Trammell & Rubio (RJTR) has been selected as project architect, Holder Construction will be the construction manager on the project, and Impact Development Management serves as owner’s representative and project manager. These team members have extensive experience in complex design and construction projects across the Southeast and the U.S.
Bob Voyles, Vice Chairman of the Authority and long-time commercial developer in Atlanta and the Southeast, said he has worked with each of these firms in the past and believes that the Authority is very fortunate to have such an experienced project team. “In my 19 years serving on this Authority, this is the most exciting and consequential project since we built the 2,750-seat Cobb Energy Performing Arts Centre in 2007. Once completed in early 2027, the rejuvenation and expansion of the convention center will assure that our facility remains No. 1 in the state of Georgia and maintains its high national standing for similar sized facilities.”

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.
Voyles adds: “We are grateful to our partners at Cobb County and the incorporated cities who funded the construction of the original facility over three decades ago with Hotel-Motel Tax (HMT) through legislation passed by the Georgia General Assembly. This lines right up with our planned expenditure of such funds for these improvements.”
