The Shimizu TRY 2004 Mega-City Pyramid is a proposed Shimizu Corporation project for the construction of a massive self-sustaining arcology-pyramid over Tokyo Bay in Japan that would have businesses, parks, and other services contained within the building.[1] The structure would house 1,000,000 people. The structure would be 2,004 meters (6,575 feet) high, including five stacked trusses, each with similar dimensions to that of the Great Pyramid of Giza. This pyramid would help answer Tokyo's increasing lack of space, although the project would only handle a small fraction of the population of the Greater Tokyo Area.[2]
The proposed structure is so large that it could not be built with current conventional materials, due to their weight. The design relies on the future availability of super-strong lightweight materials based on carbon nanotubes and graphene presently being researched. The plan was to start construction in 2030, but no further action has been taken. Shimizu is still determined to complete the project by 2110; if built, it would make history as the largest man-made structure in world history.[3][better source needed]
