Norway has completed the frame of the world's tallest timber building, which is being lauded for being environmentally friendly and fire resistant. The Mjos Tower, which is situated near and named after a lake located about 100 kilometres north of Oslo, saw its last beam hoisted by a crane this week.

Promoters say that using wood, a renewable material, makes it possible to reduce CO2 emissions compared to concrete, which is the primary material of residential buildings in cities. "Building with wood is helping us breathe in a better world," said businessman Arthur Buchardt, who added he began the project after being inspired by the Paris agreement on climate change.
