🏢Building Details

  • Completed March 2019, certified by Council on Tall Buildings and Urban Habitat as world’s tallest timber building

👷🏾‍♀️Developer & Contractor

✍️Architects & Engineers


  • Wood from locally sourced, untreated Norway spruces – so local in fact, standing atop the viewing platform you can “actually see” where the timber comes from + where it was processed

  • CLT + GLT = alternative to carbon-intensive concrete / steel – plus timber is a carbon sink, with up to 50% of its dry weight made up from the element

  • Prefabricated façade reduces waste: assembled in 5 construction stages, 4 storeys at a time, without external scaffolding

  • Structural timber is on the inside of the façade and glass elements: protecting timber from rain and sun, increasing durability, reducing maintenance

🥦 Wellbeing

  • Communal roof-top terrace overlooking Norway’s biggest lake, picturesque lake Mjøsa

  • Indoor municipal swimming pool built next door, also in wood

  • Various studies show wooden buildings promote good wellbeing: improving indoor air quality, regulating humidity + relieving stress through aesthetic quality

  • Part of a comprehensive area planning: connecting Brumunddal to wider city with new network of walking and cycling paths

🎈Bonus feature

“But isn’t it a fire hazard?!” Mjøstårnet is actually safer than most – meticulously calculated and designed to withstand up to 120 minutes of fire. Each floor is built as a separate retardant fire compartment, whereas a typical fire compartment comprises 3 floors.
