Floating City: a dream that may become a reality

Architecture studio AT Design Office has developed a project for an Atlantis-like floating underwater city.

The Chinese construction firm CCCC plans to build the ocean metropolis in an area of four square miles, with the same technologies used to build a 31-mile bridge between the cities of Hong Kong, Macau and Zhuhai.

"Part of that bridge is an underwater tunnel, which is joined by a 150-metre-long precast concrete box," underlines architect Slavomir Siska.
