Bionic Tower

The Bionic Tower is a proposed vertical city, an extremely large building designed for human habitation designed by Spanish architects Eloy Celaya, Mª Rosa Cervera, and Javier Gómez. It would have a main tower 1,228 metres (4,029 ft) high, with 300 stories housing approximately 100,000 people. The point of the Bionic Tower is to use Bionics to solve the world's rising population problems in an eco-friendly way, an incredibly difficult feat to accomplish.

The Bionic Tower is composed of two complexes put together. The first complex, Bionic Tower, is made up of twelve vertical neighborhoods, each eighty meters high. The neighborhoods are separated by safety areas to make for easier construction and evacuation in case of an emergency. Each neighborhood has two groups of buildings, one on the interior of the building and one on the exterior. Both groups of buildings are situated around large gardens and pools. The second complex, called the Base Island, is 1,000 meters in diameter, and is made up of many buildings, gardens, pools, and communication infrastructures. Foreseen uses of these complexes include hotels, offices, residential, commerce, cultural, sports, and leisure.

In 1997 work on the prototype Bionic Vertical Space began. This was developed by the architects Eloy Celaya, Mª Rosa Cervera, and Javier Gómez through the beginning of 2001. However, Eloy Celaya, who studied at Columbia University, is developing another project similar to the Bionic Tower project.

While in office, then-Shanghai mayor Xu Kuangdi expressed an interest in the concept for his city. Hong Kong also reportedly expressed interest in the project.
