The National Centre for the Performing Arts – 219.400 square meter – is located on the Chang’An Avenue in Beijing. The National Centre for the Performing Arts is separated from the Tian An Men Square by The Great Hall of the People. The building houses an opera house (2416 seats), a concert hall (2017 seats) and two theatres (one of 1040 seats) included in a titanium and glass shell which houses the public space. The glass opens the building like a curtain which we move away showing the interior : theatres, exhibition and public spaces. The titanium protects and covers, creates shadows areas more secret. The concept of the National Centre for the Performing Arts is a cultural island in the middle of a lake.
