Those who criticised the cost and design of the abstract blue Perth Arena will be dumbfounded that the building has won two prestigious architecture awards.

Perth Arena joint-venture designers ARM Architects and Cameron Chisholm Nicol won the best interior and best public architecture prizes at the Australian Institute of Architects 2013 National Architecture Awards.

It is an impressive accolade for the arena, which is marking its first birthday this weekend with pop star Beyonce gracing the stage on Friday and Saturday night.

Eager Beyonce fans have been camping outside the arena to be first in the queue for general admission spots at her Friday night show.

Elton John opened the arena on November 10 last year. Since then it has hosted diverse acts including Pink, Rihanna, Kiss and The Jacksons.

Other big acts to come soon include Bon Jovi, Dolly Parton and Bruce Springsteen.

Perth Arena is also home to the Perth Wildcats basketball team and the Hopman Cup tennis tournament.
