Japanese architects have unveiled plans forthe world’s tallest wooden skyscraper.


The 1,148-feet (350-metre) tower, housingshops, homes, offices and a hotel, will become the tallest building in Japanwhen it is completed in 2041.


Positioned in central Tokyo, the aim of the£4.2 billion ($5.9 billion) structure is to turn the Japanese capital into anenvironment-friendly city and help ‘transform the city into a forest’,architects behind the plans said.


Designs for the structure were drawn up byTokyo-based architectural firm Nikken Sikkei, but the building will beconstructed by the Forestry arm of the Sumitomo Group, one of Japan’s largestbusiness conglomerates.

该建筑的设计方案由位于东京的Nikken Sikkei建筑师事务所(即日建设计)起草,不过将会由日本最大的商业集团之一住友集团的林业部建造。

Currently referred to as the W350 Project,named after its height, it is not clear which wood or woods have been chosen asthe building material.


The tower has 70 stories above ground andis made of a combination of wood and steel, with more than 6.5 million cubicfeet (0.2 million cubic metres) of wood making up 90 per cent of theconstruction material.


Nikken Sekkei’s plans outline a braced tubestructure that is able to withstand strong winds, as well as Japan’s frequentearthquakes.


As well as offices, a hotel, shops andresidential units, the completed tower will feature a garden roof, balconiescovered with greenery, water features and large internal open spaces filledwith natural light.


Brock Commons Tallwood House, a174-foot-high (53-metre) student accommodation tower opened at the Universityof British Columbia in Vancouver, Canada, last autumn, holds the current recordfor the world’s tallest primarily wooden building.

The 24-storey HoHo Tower is set to top thiswhen it opens later this year in Vienna, Austria, with the structure set toreach 275 feet (84 metres) high upon completion.


Housing office units, apartments and ahotel, 76 per cent of the building will be constructed from wood, saving 2,800tonnes of carbon dioxide emissions over similar structures built out of steeland concrete.


A rising number of architectural firmsacross the globe are turning to wood as their primary construction material,though few match the ambitions of the W350 Project.

‘New technological advances withconstruction techniques and composite wood make this a very exciting area atthe moment’, Riccardo Tossani, who designed a retirement home on Mount Fujithat is the current largest habitable wood structure in Japan, told theTelegraph.


‘It is in many ways the ideal materialbecause it is a renewable resource as well as being somewhat recyclable.’


Before construction of the W350 Projectbegins, Sumitomo Forestry Co must first traverse stringent Japanese fireregulations.


Despite relying on wood to build houses forgenerations, Japan has largely banned the material in construction because ofits flammability – a weakness laid bare by firebomb raids on major citiesduring World War II.


Officials have begun to loosen these regulations,allowing Japanese architects to explore wooden designs


But officials have recently begun toloosen these regulations: Japan’s new national stadium currently underconstruction in central Tokyo for the 2020 Olympics Games uses wood in thedesign.


‘For Japan, it is an excellent buildingmaterial because it is readily available, it is pliable and appropriate for aseismic environment,’ Mr Tossani said.

‘Wood gives or flexes with movement in theground or absorbs movement in its joints; concrete is rigid and does not havethat flexibility, so it can crumble’.

Biodegradable building materials in a highrise. What could go wrong?

If you do some research you will find thistype of building using wood is in fact stronger than steel, cheaper, easier toinstall, more environmentally friendly. The wood is treated, fire proof, (yes Iknow hard to believe), squeezed together with other wood. Americans could dowith learning how to build better homes, unlike those blow-away houses inTornado-alley states. American houses are great in terms of design, space etc.But rubbish in their build quantity, a bit like their cars.

The longest wood treatment lasts 25 years ,that is the longest guarantee not that it actually lasts that long, they wouldbe better going for naturally oily wood like mahogany that will last over 50years.

That’ll be the world’s biggest matchstickone day….or candle.


== DebtCollecter 英国

wood has been used for building for over10,000 years and it works well


== The Highway Star

Not too avant-garde. In reality, this is asteel-frame structure with timber cladding. Timber will be pre-treated withpreservatives and intumescent materials. Long-term maintenance costs might betoo high, however, I’m sure there’s a design solution for this too.

And how many trees have been cut down tomake it environmentally friendly


== DebtCollecter 英国

better than tearing up the earth for Ironore causing pollution in the water table probably destroying land trees grownon too


== CliveMendonca 挪威

You can plant trees. They breathe carbondioxide.


== SuperDec 英国

Actually a tree absorbs more carbon dioxidein the first 3 years of its adult life, then it wanes down.

Are there termites in Japan?

Cut trees down to make a forest, Hmm

What insurance company is going tounderwrite the fire risk?

Wooden buildings are much more flexible inearthquakes than rigid stone or concrete structures. That is why housing in NewZealand is mostly of wood or wooden framed… early British settlers learnedthe hard way that what worked in their old country would not withstand theseismic activity of the new. Also, buildings can now be constructed with rubberbase isolators that minimise shock.
