Oslotre Architects, based in Oslo, has completed the Lumber Building 4, an “all-timber office building” featuring a curved wooden façade in Kristiansand, Norway. Spanning 3,106 square meters, it is the largest and first mass timber commercial building in southern Norway.
Oslotre Architects reports that Lumber Building 4 is economically competitive compared to traditional steel and concrete structures. Constructed in record time with innovative solutions and a high level of prefabrication, the building reduced greenhouse gas emissions by 53% and aligns with environmental taxonomy standards.
Entirely built from wood, the structure provides protective, insulating, and structural benefits. The six-story Lumber Building 4 now serves as the headquarters for Green Tech companies, with offices occupying the upper five floors and retail space on the recessed ground floor.
