Although activity is high, it is surprisingly quiet inside the construction site of a high school extension in Sickla, a former industrial area in south Stockholm that is set to become part of the “largest mass timber project in the world” according to the Swedish urban property developer Atrium Ljungberg.
Just a few months remain until students enter the premises, but there is no sound of drilling or pounding against concrete walls. The scent of wood is unmistakable, and signs of the material can be spotted everywhere – from glulam (glued laminated timber) columns and beams in the building’s frame to cross-laminated timber (CLT) slabs in the floors, ceilings and staircases. CLT, made by gluing together layers of planed wood into panels, offers strength and rigidity comparable to concrete but is significantly lighter and quicker to build with.
