The $400 million expansion Adelaide Convention Centre is well underway with demolition of Australia’s first purpose built convention centre completed to make way for Australia’s newest one.

The Centre’s new East Building will be constructed on the site of the Centre’s original plenary and link seamlessly into the current Central and new West Building via an internal Sky Walk. The West Building, stage one of the Centre’s expansion, was officially opened in March.

The new East Building will house a multi-purpose, state-of-the-art facility, which reaches out over the Riverbank Promenade and capitalises on the expansive views over the River Torrens towards Adelaide Oval.

The East Building will be able to be subdivided and configured within minutes as pre-function space, ballroom, exhibition or plenary with capacity of up to 3,500 seats.

The building will feature a new auditorium with hinged seating stored in the roof space, which can be lowered in minutes to convert from exhibition space to lecture theatre style space. Two, 18 metre diameter rotating seating drums in the auditorium can be rapidly turned and reorientated to change from a large open plan theatre setting to separate, more intimate group seating arrangements for approximately 350 delegates.

The new East Building is scheduled for completion in 2017.
