Proposed by Kajima Construction designed by Sadaaki Masuda and Scott Howe Would be able to house up to 40,000 peopleĪimed at helping put an end to major congestion and lack of greenspace in the Tokyo 400 m (1,312 ft) wide at the base for a total floor area of 8 km 2 (3.1 sq mi) drawn by construction firm Takenaka for the city of Tokyo in 1989, its design was the first of the modern super-tall mega-structures to gain serious attention and consideration by any governmentĭesigned by 元5 Arquitectos articulated in nine modules Planned as part of the proposed "Khazar Islands" project ĭesigned by architect Henning Larsens Tegnestue A/S īy Eric Kuhne and Associates Like the pyramids of the Mayans and Egyptians, this structure in Dubai would be a giant it would cover 2.3 square kilometers and would be able to sustain a community of up to one million people.Ĭommercial, retail, and leisure real estate The structure was designed to house nearly one million people and would be self-sustainable with all-natural energy sources. Ziggurat Pyramid is a pyramid-shaped arcology that was conceived for Dubai in 2008. Shanghai and Hong Kong have both expressed serious interestĭesigned by architects Eloy Celaya, Mª Rosa Cervera and Javier Gómez Pioz would house about 100,000 people. Xtopia is a concept building for a 300-floor high-rise self-contained community. Would serving as a dam and supplying water to its 55,000 residents The aims of the project are to reach a nautical mile in height while "not using concrete, orthogonal grids, traditional systems, mortars, cranes." If built, the tower would reach 1,852 metres (6,076 ft). ĭesigned by architect Omero Marchetti as part of his proposed "ethic city" concept. "De Nederlandse Berg", Dutch for "The Dutch Mountain" is a proposal for an artificial mountain by Thijs Zonneveld. Tourism, leisure, commercial and wind generation If built, it will be the largest man-made structure on Earth. The structure would be approximately 14 times as high as the Great Pyramid of Giza, and would house 750,000 people. The Shimizu Mega-City Pyramid is a proposed project for construction of a massive pyramid over Tokyo Bay in Japan. Residential, commercial, retail, and leisure real estate Residential, commercial, and retail real estateĭesigned by American architect Eugene Tsui in 1991 Would accommodate five hundred thousand to one million inhabitants Residential, commercial, retail real estate, as well as heavy industry The cost would be around ¥3 quadrillion ($22 trillion).
Would house roughly 30 million people and take 100–150 years to build. It has a long (1000–1500 km) vacuum tube, levitated via strong currents in superconducting cables

The structure would be free standing and actively guyed over its base. Tourism, communications, wind generation, andĪ sub-orbital or mini version. The Launch loop is a concept that has been proposed for the purposes of orbital launch. Multiple tethers can be connected from orbital ring to the ground enabling mass-transport to space. A motorized platform is placed on the cable that runs in the opposite direction at the speed that makes the ring structure become stationary relative to the ground at much lower attitude compare to space elevator which has to maintain its center of mass around geostationary orbit. The Orbital ring is a concept of an artificial ring shaped cable placed around Earth and set rotating at such a rate that the apparent centrifugal force is large enough to counteract the force of gravity.
