A shortlist of architects has now been established for the Green Square Aquatic Centre in Sydney, Australia.

The centre will form part of the commercial, retail and cultural heart of the AU$8bn (US$7.5bn, €5.6bn, £4.4bn) greater Green Square redevelopment – one of the largest ever urban renewal project in Australian history.

The five finalists are all from Sydney – Andrew Burns; Cullinan Ivanov Partnership; CHROFI & McGregor Coxall; Andrew Burges Arhitects; and TYP-TOP Studio (Andrew Daly and Kevin Liu).

Short-listed designs include sunken pools surrounded by wetlands, evoking the region’s pre-industrial heritage and a moonlight cinema.

When complete, the AU$50m aquatic centre will include an outdoor 50m swimming pool, an indoor 25m pool, a leisure pool, a hydrotherapy pool and a gym.

The finalists are now expected to "refine their entries" in the next stage of the competition and the winner will be announced later this year.
