Architecture firms Snøhetta and Blight Rayner have won an international competition to design an AU$150m (US$103.8m, €90m, £81.4m) theatre for the Queensland Performing Arts Centre (QPAC) in Brisbane, Australia.

Set to open in 2022, the pivotal facility, which will turn QPAC into the largest performing arts centre in Australia, will feature two studios, foyer spaces, and an expansive glass façade.

"The building will glow by night and sparkle by day with just a glimpse of the glass visible from the city side," explained Queensland Government Architect Chair, Malcolm Middleton.

According to the state's Minister of Arts, Leeanne Enoch, the design will also help to promote new forms of cultural storytelling.

"It recognises First Nations Peoples and the cultural significance of South Bank, drawing inspiration from the Brisbane River as both an important meeting place and a place for telling stories," she said.

Currently, QPAC attracts seven million visitors annually. When operational, the annex could attract an additional 300,000 people per year to the venue.
