The reason for the refurbishment and extension of the building was that the technical services were out of date and was in need of modernizing to comply with current requirements for office environment. Sparebanken NOR (now DnB) was the only one of the country’s four largest banks not to build a new headquarters during the economic boom of the late 1980’s.
The building was originally completed in 1920 as headquarters for the ‘Centralbanken’. Since then it has been the headquarters for ABC Bank and later for Sparebanken NOR.
The building`s architect, Waldemar Hansteen, assisted by Henrik Bull, were inspired by a number of different architectural styles. The building is characterized by the contrast between the curved lines of the rotunda and the more rectangular flanks typical of the late Jugendstil or early Art Deco.
An important part of the remodeling was the restoration of great architectural details, such as the skylights, marble counters and columns, to their original beauty and elegance. These elements have also been given a modern interpretation in the new oak wall coverings, glass walls and lighting. The new canteen occupies the previous banking hall, surrounded by meeting rooms and the brokers` department.
