The World's Tallest Wooden Skyscraper Built in Norway

Building offsite with wood is trendy and environmentally friendly.









“Mass timber” construction is derived from old techniques of post-and-beam construction but uses advanced technologies, including cross-laminated timbers (CLT) and laminated veneer lumber (LVL), which feature layers of wood bonded with adhesives and produced as either beams or panels. 

Some concrete and steel were used around elevator shafts or stairwells in mass timber construction, but floors and beams were made entirely of wood.


Structural wood products like CLT are lighter than conventional materials, require less energy to make than either steel or concrete (and thus produce lower emissions), and can sequester carbon.

Their relative lightness makes it possible to assemble floor and wall sections off-site and ship them to the building site, significantly reducing the amount of building time required. 


Prefabrication also means that building structures can be designed to maximize energy efficiency since individual components can be built precisely in a factory, minimizing errors and ensuring that measurements are exact.


Tall wooden buildings store carbon, preventing it from entering the atmosphere by sequestering it in the building for decades. In contrast, buildings made of steel and concrete generate large amounts of carbon emissions per tonne of material produced.
