Ever wondered how tall the tallest building ever designed is ?Before you try let me remind you the tallest building in world at present is the Burj Dubai(still under construction ) at 1,680 ft and will be 2,275ft when finished.
Well, The largest building ever to be envisioned and designed fully is X-Seed 4000 .The X-seed 4000 is 13,123 ft (4 km) tall steel construction of 800 floors with a 6km base, the building was designed to be built in water in the Tokyo bay.Beating even the tallest structures dozens of radio and television broadcasting towers which measure over 2,000 ft.

Roughly based on the japan mount Fuji's structure ,this building would house somewhere from half a million to a million people. The X-Seed 4000 would cost about $ 300-900 billions US.

Being designed by Taisei constructions as an " Intelligent building" the X-SEED 4000 would maintain light temperature and air pressure in response to changing extreme weather condition.

Really wonder if this building will ever be made?
