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.

"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."

The "Floating City" is probably the most ambitious underwater architecture project ever imagined and put on paper. It will feature green spaces, residential, commercial and cultural facilities, and a complex scheme of underwater tunnels, roads and walkways.

The underwater city will have noise, waste and other environmental impacts managed via innovative strategies. Part of the entire structure will be above water level.

Will the modern Atlantis ever see the light of day? Are we heading for the water world?
