Office building working with a full life-cycle focus on sustainability

Innovative wood construction in the centre of Oslo if setting a new standard for the future of office buildings.

Developed by: Lund+Slaatto Arkitekter & NCC

Situated in Oslo, Valle Wood – with 6,700m2 of office space – is the largest massive wood construction project for commercial use in Norway. The project has taken a holistic and highly ambitious approach to environmental protection in the construction phase, minimising energy use, waste, transport and use of chemicals. The building will have a green roof, and be certified in accordance with one of BREEAM’s highest level of certification, which takes a full view of the building’s entire lifecycle perspective. It is expected that the building will have 40% less energy consumption than similar office building, savings that can be passed on to tenants.

Valle Wood was designed with a distinct identity, to stand out from the surrounding concrete and steel buildings, thanks to its dynamic wood façade. Inside the building, wood will be the dominant material, even the elevator shaft and the stairs between the floors are made from wood. The emphasis on exposed wood in the building aims to create a pleasant and healthy working environment.


The glulam beams and columns are Norwegian produced, while all the massive wood panels and slabs are from an Austrian CLT producer. Assembly is around 2.5 weeks per floor, with CLT wall elements spanning over two floors. In total there will be 7 floors, taking the wood building to a height of 28 meters.
