- Mjøstårnet, a mixed-use tower in Brumunddal, Norway has been named as the tallest timber building in the world by the Chicago-based Council on Tall Buildings and Urban Habitat (CTBUH).
- Designed by Trondheim, Norway–based Voll Arkitekter, Mjøstårnet tops out at over 280 feet in height.
- The mixed use building contains a hotel, office space, residential units, and event spaces.
The Mjøstårnet tower consists of 18 stories with different uses. The official height is 85,4 meters. With a footprint of only 17m in width and 37,5m in length, each floor is about 640 m2. The total floor size for the tower is about 10 500m2. There is an additional 4 900m2 for a public bath facility that adjoins the building.
The ground floor is public, with lobby, reception and restaurant. In addition, there is an adjoining public bath on the ground floor with two 25 meters length pools. The second story is reserved for rentable meeting rooms and technical facilities. The next five stories are office space.
The Mjøstårnet also has 72 hotel rooms, 18 on each floor from the 8th story to the 11th. In total there are 33 apartments in the project, ranging from 50m2, to 180m2 from the 12th to 16th floor.
There are two apartments on the 17th floor together plus an event room, used for weddings, celebrations and larger conferences. On the top floor there is one penthouse apartment and a public viewing terrace.
The main load bearing consists of large-scale glulam trusses along the façades as well as internal columns and beams. The trusses handle the global forces in horizontal and vertical direction and give the building its necessary stiffness. CLT walls are used for secondary load bearing of three elevators and two staircases.
Voll Arkitekter designed the tower and the story layout. They comment “Mjøstårnet is our first building where we really exploit the tree’s properties to the fullest as construction material. We think it’s exciting to see that wood construction has gained a new renaissance, considering recent experiences with the tree’s environmentally friendly impact on greenhouse gas emissions.”
