Forget steel and concrete — wood is the latest go-to material for building skyscrapers. The renewable resource has high potential.  “The world’s tallest wooden house!” reads a huge poster on the side of a building under construction in the Norwegian municipality of Brummundal. The house doesn’t have any scaffolding; cranes and an outdoor elevator are used to transport the building material to where it’s needed. The wood is sourced from Norwegian forests. …But despite the declaration on the poster, this is not actually the world’s tallest wooden house after all. Vienna is currently working on an 84-meter-tall wooden building 24 stories tall (with a staircase made out of cement). The building in Vienna will also combine apartments with offices, shops and a spa. Ask the Austrians and they will tell you they’re the ones who came up with the concept of using wood as an industrial product. Austria is the world’s largest producer of cross-laminated timber.
