The world’s tallest wooden skyscraper is to be built in Japan, providing 8,000 apartments with trees and foliage on balconies at every level.
The 350-metre high-rise building in Tokyo is expected to cost £4 billion to build and is due to be completed by 2041, the 350th anniversary of the foundation of the company that hopes to build it.
Currently referred to as the W350 Project, named after its height, it is not clear which wood or woods have been chosen as the building material.
The tower will be seven times taller than the 17-storey block of student flats in Vancouver that holds the title of world’s tallest wooden skyscraper and 40 metres taller than London’s Shard, by far the capital’s highest building.
Sumitomo Forestry intends to use wooden materials to construct 90 per cent of the 70-storey building.
Because there are frequent earthquakes in Japan, a steel frame with vibration control braces will be part of the structure, but the interior will be entirely wooden, “producing a calm space that exudes the warmth and gentleness of wood”, say the planners.
There will be balconies on all four sides and foliage running up the full height and the developer hopes it might one day form part of a cluster of similar buildings bursting with greenery that will create habitats for birds and insects and contribute to the biodiversity of urban spaces.
The World’s Tallest Wooden Buildings
Wooden skyscrapers can be found across the globe, from an 18-storey office building in Minneapolis made from timber to a 53m-high block of student flats in Vancouver that currently holds the title of world’s tallest wooden skyscraper.
Brock Commons Tallwood House, a 174-foot-high (53-metre) student accommodation tower opened at the University of British Columbia in Vancouver, Canada, last autumn, holds the current record for the world’s tallest primarily wooden building.
Other wooden sky scrapers are currently under proposal with a 244-metre building in Chicago being considered.
