Construction of Perth’s new indoor sports and entertainment centre, Perth Arena, is now complete.Located on the northern fringe of Perth’s CBD, the new stadium is expected to bring more than 250,000 people into the City Link precinct each year and is the catalyst for the renewal of the whole precinct, re-establishing a connection between Perth’s commercial and entertainment hubs.Perth Arena features a retractable roof that can open and close in 14 minutes allowing natural light to flood the centre court, state of the art acoustics, function spaces, corporate hospitality suites, cafes and a basement car park. The stadium has a very flexible design, allowing for crowds of up to 12,000 in concert mode and up to 15,500 in tennis mode. Alternatively, the Arena can be closed down for an intimate concert with 3000 people. The stadium can accommodate shows with a centre stage or end stage and performances in the round such as motocross, equestrian and ice shows.Perth Arena has been designed as a landmark structure with an internationally recognisable and innovative design based on the Eternity Puzzle and inspired by the 12-sided Round House in Fremantle, which is one of Perth's oldest buildings. The striking Yves Klein blue exterior is continued through the interiors and is complemented by warm timber panelling and splashes of red, orange and yellow.Perth Arena is a world-class sporting and entertainment facility and iconic landmark in the Perth CBD. With it’s striking puzzle-like form and bold interiors the venue has a maximum capacity of 15,500 patrons and has been designed to cater for configurations suitable to a wide range of events and performances. It also features a range of sustainability initiatives, including one of the largest PV (solar) arrays installed on any building in Western Australia.The project was a joint venture by ARM Architecture and Cameron Chisholm Nicol.
