World's Tallest All-Timber Building Nears Completion

MJØSTÅRNET, the world's tallest all-timber building, is almost complete as seen in new drone footage released by Woodify, the company that has manufactured the structure's cladding.

Reaching an unprecedented height of 84 metres, the tower is built without using steel bracing or a concrete core - which are common elements that help provide stability in timber high-rise buildings.

The structure is a true showcase, combining a hotel, apartments and office space into a development that demonstrates mass timber's viability for a number of different building types.

Structural beams and bracing are made from glue laminated timber (glulam), while the walls are formed with cross laminated timber (CLT) produced by Norwegian manufacturer and developer Moelven.

The building's external cladding consists of thermally treated, fire retardant timber planks.

There has been a growing interest in timber buildings and mass timber - whether glulam or CLT - is now widely seen as a viable in mid-rise schemes.

Building with mass timber can bring a number of benefits, including shorter build times, lighter structures and reductions in a building's carbon footprint.

However, the UK's Grenfell tower disaster has prompted a review of building standards in the country and some worry this may slow down the adoption of CLT, which is often misconstrued as a highly flammable material.
