From Wildness to Information Era, rapid urbanization and immoderate resource consumption has not only devastated the natural environment but also bred numerous urban problems. After recalling the evolution process from nature to urban, we audaciously purpose a concept of building a “Floating, Evolutionary, Secondary Ecosystem” over the city, aiming to enable the future city to transform back to the superior eco-condition of Wildness allowing civilians to dwell between nature and urban enjoyably.

Using Beijing CBD as example, several eco-techniques such as rainwater collection, photovoltaic, air purifying thin-film, and eco-phytoecommunity planting, are considered as measures in the “Floating City” to combat Beijing’s environmental problems of water and energy shortage, air pollution, heat-island, etc. Moreover, based on the concept of “Vertical Urban Functional Distribution,” we integrate functions as residence, interaction, and relaxing into the design, in which the complex horizontal transportation system could be minimized and residents would have a more affluent urban experience.

In the overall design, the whole floating city is separated into three parts in the overall design: the components, the structure, and the façade. We extract correlation factors from the site as the parameter to generate and control the configuration. Firstly, we select four basic points with lower building density according to precise site analysis. Secondly, we use a random system to insert three different functions (residence, entertainment, interaction) with a certain ratio into the floating city. Except for the functional equivalence, the areas of these functions should also match with the bottom city. Finally, we use a genetic algorithm to optimize the sunshine amount by calculating the position and the area of the holes that we are trepanning on the upper platform.


For the detailed design, firstly combining curve typing with quantity control can help us generate the most suitable combinations of our components. They can perfectly fit in with the current architectural form. Then, take advantage of the field system to control the variation tendency of the components both in plane and height. Next, the whole floating structure is generated by network system. Finally, for specific design on components, each component has its own parametric control according to particular analysis on using area, function, and form.
