A Chinese company wants to build this incredible four-square-mile floating underwater city using the same techniques they're using for the construction of the 31-mile bridge that links Hong Kong, Macau and Zhuhai. It's incredible—the kind of stuff I dreamed about when I was a little kid.
The China Communications construction company commissioned AT Design Office to plan the ocean metropolis. They are now in talks with a large Chinese investor group to decide whether to pursue the project or not.
Of course, some of the parts in the renders would be so prohibitively expensive to make that I doubt that they would make it to the final project but, according to architect Slavomir Siska, the city is entirely doable using the same techniques they are using to build the bridge, which will be finished next year after construction began in 2009:
Part of that bridge is an underwater tunnel, which is joined by a 150-metre-long precast concrete box. The mega box is cast on a nearby island and floated to site before being connected. We were appointed to work with the engineer to come up with a masterplan for a 10-square-kilometre floating island that can be built with the same technology.
One of the coolest things about this project is that it has underwater and above water levels.
