Oslo Opera House

The Oslo Opera House (Norwegian: Operahuset) is the seat of The Norwegian National Opera and Ballet, and the national opera theatre in Norway.

The Storting decided on the 15 Juny 1999 to build a new opera house in Oslo. The construction started in 2003 and the Opera House was finished in 2007 with the opening event held on 12 April 2008. King Harald V of Norway opened the Opera House that evening at a gala performance attended by national leaders and royalty.

The architects were the Norwegian firm Snøhetta who were also the architects of the Bibliotheca Alexandrina (the Library of Alexandria) in Egypt. The theatre designers were Theatre Projects Consultants based in London, the acoustic designers were BrekkeStrandArup, a joint venture between local consultant Brekke Strand Akustikk and international acousticians Arup Acoustics. The Opera won the culture award at the World Architecture Festival in Barcelona in October 2008. In April 2009, the Opera House was pronounced the winner of the 2009 Mies van der Rohe award.

The structure provides a total area of 38,500 m² and includes 1,100 rooms, one of which has 1,350 seats and another has up to 400 seats. Total expenditures for the building project were planned at 4.4 billion NOK, but finished ahead of schedule, and 300 million NOK under budget. At the 1-years jubilee of the opera 1.3 million people had visited the building.
