Sumitomo Forestry, an industry giant in Japan, [is] pivoting to plyscrapers and proposing a 70-story, 350 meter (1148') tower for the Marunouchi district in Tokyo. It's called W350, the plan being that it will be finished in 2041, the 350th anniversary of the founding of the company.
[...] Using a hybrid 9:1 ratio of wood to steel, Sumitomo Forestry aims to replace concrete, which is one of the world's largest carbon footprint contributors. The skyscraper would be a 70-floor mixed-use building that would include a hotel, office space, commercial space, and residences. Wrap-around balconies at different intervals would be planted with lush wildlife. And greenery would extend throughout the entire complex, creating a vertical forest where humans and wildlife can flourish.
[...] It is a brace tube structure, "a structural system that forms a cylindrical shell (brace tube) with columns / beams and braces. By placing braces diagonally in a set of shafts assembled with columns and beams, it prevents the building from deforming against lateral forces such as earthquakes and wind."
The images are beautiful.

They say it was Jets, you may find it was THERMITE. We went after Iraq, they did not knock down the World Trade Center. It wasn’t the Iraqis that knocked down the World Trade Center, we went after Iraq, we decimated the country, Iran’s taking over, OK? But it wasn’t the Iraqis, you will find out who really knocked down the World Trade Center. Because they have papers in there that are very secret, you may find it’s the Saudis, OK? But you will find out.
