As rising sea levels threaten low-lying nations around the world, floating cities are gaining political backing and some serious investment.

Has the time come for floating cities ? A possible solution for demographic growth and rarefaction of available land ?

Some architectural projects of the 1960s explored and colonized the vastness of the ocean.

SEA CITY

Hal Moggridge, John Martin, Ken Anthony ; 1968 ; An experiment for a marine city

A self-supporting island made of concrete and glass, a sheltered lagoon for floating islands, housings and machine industries.

TRITON CITY 

Buckminster Fuller ; 1960 ; A study of a prototype Floating Community

A concept for a tetrahedronal and anchored floating city for Tokyo bay.

“Three-quarters of our planet Earth is covered with water, most of which may float organic cities. Floating cities pay no rent to landlords. They are situated on the water, which they desalinate and recirculate in many useful and non-polluting ways. They are ships with all an ocean ship’s technical autonomy, but they are also ships that will always be anchored. They don’t have to go anywhere. Their shape and its human-life accommodations are not compromised, as must be the shape of the living quarters of ships whose hull shapes are constructed so that they may slip, fishlike, at high speed through the water and high seas with maximum economy. Floating cities are designed with the most buoyantly stable conformation of deep-sea bell-buoys. Their omni-surface-terraced, slop-faced, tetrahedronal structuring is employed to avoid the lethal threat of precipitous falls by humans from vertically sheer high-rising buildings.” (Fuller)

PNEUMATIC CITY – FLOATING DYODON

Jean-Paul Jungmann ; 1967 ; a floating and inflatable structure – The unbearable lightness of architecture

“It was a complicated job as “Lightness” deals with many different subjects that, somehow, are all interrelated by analogies, in shape, structure, process or the idea behind them. Likeness apparently trascends time, origin and professional specialism.” (Adriaan Beukers and Ed van Hinte)

Air is so poetic, ephemeral and untouchable.
