The design calls for a cone-shaped pyramid 840 meters high, with a base about as big as the Tokyo Olympic Stadium and glass sides for natural lighting.
The tower is a self-contained arcology containing one million square meters of commercial development and housing for 60,000 people, split into sections.
Offices and light or clean industries are in the lower levels, apartments above, and the top section houses communications systems and wind or solar generators.
Horizontal and vertical high-speed metro lines provide long-distance travel, with cars designed to carry 160 people stopping at intermediate five-story 'sky centers' on every thirtieth floor.
The design firm's web site states that "the project demonstrates that high-density or high-rise living does not mean overcrowding or hardship; it can lead to an improved quality of life, where housing, work and leisure facilities are all close at hand".
