Mjøstårnet is an 18-storey mixed-use building in Brumunddal, Norway.

It is officially the world's tallest timber building, at 85.4 m (280 ft) tall. Mjøstårnet translates as “the tower of lake Mjøsa”. The building is named after Norway’s biggest lake, which it is located next to.

Designed by Norwegian studio Voll Arkitekter, Mjøstårnet has a combined floor area of around 11,300 m2 (122,000 sq ft).
The building offers a hotel, apartments, offices, a restaurant and common areas, as well as a swimming hall in the adjacent first-floor extension. This is about 4,700 m2 (51,000 sq ft) in size and are also built in wood.


All 72 hotel rooms are equipped with electric underfloor heating installed in bathrooms. For this a robust heating cable with concealed joint was used meeting the M2 requirements of the tough IEC 60800: 2009 standard. The heating cables have a 20-year warranty.

Mjøstårnet has already received both national and international recognition for the building with the awards "Norwegian Tech Awards" in the category Building and Construction and Gold in the "New York Design Award 2018" in the category "Architecture - Mixed Use - International".


The world’s tallest wooden tower in Brumunddal where emphasis has been placed on using materials using expertise from the local area, is gaining a lot of international attention. It shows great potential for making construction greener by using more wood.

Mjøstårnet is an innovative example of a sustainable building in an industry responsible for huge emissions.
