Plans to build $5.6 billion timber skyscraper in Tokyo have been put in place

Plans are underway to build the world’s tallest timber tower in Tokyo, Japan. Japanese lumber and housing firm, Sumitomo Forestry could potentially break the current record by constructing a timber tower rising to an ambitious 350m (1,148ft) tall.

If this project goes ahead, the tower, named the W350, will reach an impressive 70 floors and will house office space, hotels, retail premises and apartments. Totalling an impressive 455,00sq m (4,897,579 sq ft) of floorspace, the roof will be turned into a green space to reflect the building’s eco-friendly ethos. 

Sumitomo Forestry said: 

"The planned structure is a hybrid wood and steel structure made from 90 percent wooden materials. It will use a braced tube structure in which steel frame vibration control braces (diagonal braces) are positioned inside a column and beam structure, made from a combination of wood and steel.”

“The outermost side is designed with balconies that continue around all four sides of the building. The balcony part gives the high-rise building a space in which people can enjoy fresh outside air, rich natural elements and sunshine filtering through foliage. The greenery connects from the ground to the top floors through the balcony part, and it offers a view of biodiversity in an urban setting."

The total construction cost of building the world record breaking towers is estimated at a staggering 600 million Yen (around $5.6 billion) and construction will not begin until 2041, by which time Sumitomo is hoping that technological advances in timber construction will assist in lowering costs.
