The Oslo Opera House is the home of the Norwegian National Opera and Ballet, and the national opera theatre in Norway. The building is situated in the Bjørvika neighbourhood of central Oslo, at the head of the Oslofjord. The main auditorium seats 1,364 and two other performance spaces can seat 200 and 400. The angled exterior surfaces of the building are covered with marble from Carrara, Italy and white granite and make it appear to rise from the water.
The roof of the building angles to ground level, creating a large plaza that invites pedestrians to walk up and enjoy the panoramic views of Oslo. While much of the building is covered in white granite and La Facciata, a white Italian carrara marble, the stage tower is clad in white aluminium, in a design by Løvaas & Wagle that evokes old weaving patterns.
The lobby is surrounded by 15 m (49 ft) tall windows with minimal framing and special glass that allows maximum views of the water. The roof is supported by thin angled columns also designed not to interfere with views.
Interior surfaces are covered in oak to bring warmth to spaces in contrast to the coolness of the white exterior. The main auditorium is a horseshoe shape and illuminated by an oval chandelier containing 5,800 handmade crystals.
