Plans for an underwater city, capable of housing 5,000 residents has been unveiled by Japanese construction firm Shimizu Corporation.

The concept for the Ocean Spirals consists of a floating 500 metre wide sphere connected to a resource centre located on  the ocean floor via a 15km helix-shaped path, made from resin components that are produced using massive 3D printers.

The ‘spirals’ are able to descend 2.5 miles below the ocean’s surface, creating self-sustaining underwater communities.

Each of the floating domes will contain business and residential zones, and hotels which would submerge underwater during bad weather.

The spirals, that descend from the domes, allow scientists to create an “earth factory” of natural resources may be harvested for energy and materials.

Shimizu has predicted that the first spiral will take five years to build, estimated to cost about $25 billion.

The firm. which has previously worked on a space hotel and a floating city, says the technology to sustain life under the sea will be completed in 15 years, allowing residents to move in by 2030.

The concept for Ocean Spirals was developed in collaboration with Tokyo University as well the Japan Agency for Marine-Earth Science and Technology.
