Abstract
Solutions to the urban problems of the future must assume the new reality of megacities. The inevitable
technological progress must find a balance with the ‘bio-ecological' recovery of the natural environment. In the vertical
bionic city, all these occur; bio intelligence and giant structures of the city are merged into a single. These structures try
to survive by relying on working together as a single organism alive, as ants work in their nest. What makes them so
efficient? What makes them work all together? What will be the future form of our building environment? Our future
habitable environment is more likely to be in a vertical built form, against the horizontal city form. There are many
reasons to believe that the new vertical cities will be more sustainable than the conventional horizontal cities. If this logic
is accepted as the future scenario, then the question facing all planners and architects today is: Should we take this
built form and make it more socially accepted, physically habitable, and human? This paper examines some of the key
implications of this scenario, and the criteria for the design and planning of our future sustainable built environment as
the vertical cities in the sky.
