About W350 Tower

Timber is expected to make up 90 per cent of the hybrid structure, with 185,000 cubic meters of wood planned to be used in its construction.

The building would use a "braced tube structure" with columns and beams made from steel and timber, supplemented by additional diagonal steel braces.
