The neighborhoods are separated by safety areas, designed to make for easier construction and evacuation in the case of emergency.

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.

This was developed by the architects Eloy Celaya, María Rosa Cervera and Javier Gómez through the beginning of 2001.

Eloy Celaya, who studied at Columbia University, is developing another project similar to the Bionic Tower.
