Japanese company plans world’s tallest wooden building

February 22, 2018

A Japanese company is planning to build the world’s tallest wooden skyscraper, to mark its 350th anniversary in 2041.

Sumitomo Forestry said 10% of the 70-storey W350 tower would be steel, combined with about 180,000 cubic metres of indigenous wood.

There will be about 8,000 homes, with trees and foliage on balconies at every level, it said.

How much will the skyscraper cost?
The projected cost of the building is about 600bn yen (NZ$7.6billion), about twice the cost of a conventional skyscraper of the same size.

However, Sumitomo says it expects costs to fall before the building’s 2041 scheduled completion date due to technological advances.

How environmentally friendly is it?
Concrete and steel buildings leave behind a carbon footprint, and are thought to be responsible for about 8% and 5% of global emissions respectively.

Wood, on the other hand, stores carbon instead of emitting it back into the atmosphere.

Japan also has large forests, covering approximately two thirds of land area.

What challenges are there in a project like this?
Fire-resistance is obviously one key factor.

However, cross-laminated timber (CLT), a building material that is becoming more common, is designed to be fire resistant and unlike steel, remains more structurally stable when subjected to high temperatures.

It’s a lot more expensive to build a wooden skyscraper, so chances are you’re not going to see them pop up across your neighbourhood anytime soon.

Huh. Neat.

That's risky

7.6 Billion dollars just for one building seems a bit much, but not really considering the expense of all the safety precautions.
