X-Seed 4000
The X-Seed 4000 is the tallest building designed ever in the human race. The designs of the construction have been completed by Taisei Corporation. Which was designed for Tokyo, Japan.
This X-Seed 4000 "was never meant to be built" says Georges Binder, managing director of Buildings & Data. The purpose of the plan was to know the skill ability of the company and contractors, which I think.
