The Copenhagen-based architecture studio said the arena would be a "modern-day colosseum" for the city, as part of the Nygardstangen district development.
"In developing this new arena, we considered the characteristics of Bergen as it is now, and envisioned how it can be in the future," said Jan Ammundsen, senior partner and head of design at 3XN.
"In our design we have tried to solve the urban and infrastructural challenges by creating an arena in human scale using warm materials, taking the local climate in to account. We will change the area from a place for cars to become a place for people."
Sn%uF8hetta makes every interior surface a canvas in new ꌐ0-million arts school in Bergen
Bergen, which is on Norway&aposs west coast, is built around a fjord and surrounded by mountains. The city&aposs waterfront is home to Bryggen, an old wharf dating from the 14th century century that is a UNESCO world heritage site.
Renderings of 3XN&aposs arena show curving timber louvres that would compliment the city&aposs historic wooden buildings, deflect inclement weather and have a planted green roof.
Along with the arena, which will host large scale cultural and sporting events, the mixed use development will include new housing, public plazas, a hotel, cinema and a police school.
In 2017 the Danish architecture firm completed a 35,000-square-metre arena with an undulating wooden facade in Copenhagen, and is building an aquatics centre in Linköping, Sweden, from curving glass and timber.
Bergen recently opened the doors of its new ꌐ0 million arts school designed by Sn%uF8hetta, featuring a mirrored facade that reflects the coastal city&aposs changeable skies.
