New spaces for Oslo’s landmark

Oslo City Hall needed an open meeting room and auditorium. Troldtekt acoustic panels were used in both spaces.

Inaugurated in 1950, Oslo City Hall with its two distinctive tall towers is an Oslo landmark, known for its exterior decoration and carillon. The city hall houses the city council, administration and other municipal organisations, and is also where the Nobel Peace Prize is awarded.

The city hall needed a meeting room outside the internal security zone and an auditorium.

The meeting or “social" room, is an open space overlooking the building's entrance hall towards Oslo Fjord, from where a staircase leads directly up to the room. It can accommodate both large and small groups that need to hold a meeting or meet for lunch, for example.

Troldtekt acoustic panels were chosen for the walls of the room, making it possible to hold a meeting and sit undisturbed by noise from the entrance hall or others in the room. The acoustic panels are painted in a shade of pink from the city hall’s colour scheme that matches the marble present in the building, making the new meeting room an integral part of the entrance hall and the rest of the large, open space.

A former archive room has become the city hall’s new auditorium, which can seat 150 visitors. Troldtekt rhomb mini design solution in natural wood was chosen for the walls. The colour of the panels is separate from the city hall’s colour scheme in order to delineate the new space, while the auditorium’s seats remain part of the city hall’s colours. Together, the acoustic panels and the colour of the seats create a warm atmosphere in the room while effectively absorbing sound.
