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.

A "braced tube structure", diagonal steel vibration-control braces at the centre of a 350m (1,150ft) wood and steel column, would protect against Tokyo's regular earthquakes, it said.

 

How much will the skyscraper cost?

The projected cost of the building is about 600bn yen (£4.02bn; $5.6bn), 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.

 

 

Is the concept of a wooden skyscraper new?

No. Japan actually passed a law in 2010 requiring construction companies to use wood for public buildings that are below three storeys high.

 

It's not a new concept worldwide either.

 

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.

 

 

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.

 

 

What do you guys think?

Would you like to stay there if they built it?

Healthy trees dont fall down during an earthquake, Makes sense to build your sky scraper out of tree.

There are types of wood that are stronger, more flexible and fire resistant than steel, and have a longer lifespan than modern steel reinforced concrete structures.

I don't believe it. I'm in the final year of Architecture and have spoken specialists who think 20 stories is the limit.

Obviously steel framed and some kind of glue reinforced wood. Would be pretty cool if 90% of the build was made with wood.

I'm sure I could get it done with a large supply of Balsa Wood.
