Scalloped sections of green-painted timber clad the facade of Lumber 4, a mixed-use building in Norway designed by local consulting agency Oslotre to demonstrate the capabilities of timber construction.
Located in an industrial area on the outskirts of the city of Kristiansand, Lumber 4 comprises a ground floor with commercial spaces and five floors of office space above.
