Pyramid City

by Shimizu Corporation
Tokyo Bay, Japan

The Shimizu TRY 2004 Mega-City Pyramid is a proposed project for construction of a massive pyramid over Tokyo Bay in Japan. The structure would be 12 times higher than the Great Pyramid at Giza, and would house 750,000 people. If built, it would be the largest man-made structure in Earth’s history. The structure would be 2,004 meters high and would help answer Tokyo’s increasing lack of space, although the project would only handle 1/47th of the Greater Tokyo Area’s population. The idea partially stems from the fictional architectural marvel of the Tyrell Corporation, which appear several times in the 1982 science fiction film Blade Runner, as a duo of futuristic pyramidal structures. The proposed structure is so large that it cannot be built with currently available materials, due to their weight. The design relies on the future availability of super-strong lightweight materials based on carbon nanotubes.
