Sustainably designed floating cities for a future world that shimmers green

With dwindling land resources and the need to curb pollution, while still providing ample living space for the generations to come, architects have long envisioned sustainable developments that can float on the surface of water. Considering the fact that more than 70 percent of the surface of our planet is covered in water, the plans seem a viable alternative too. Here we bring to you some of the most creatively thought out plans that could well materialize in the near future, providing fully functional cities far from the land as we all know.

New Orleans Arcology Habitat:

The brainchild of Ahearn Schopfer Architects, the New Orleans Arcology Habitat has been designed to be located in New Orleans. The concept includes space for 20,000 housing units, three hotels, 1500 time share units and 50,000sqf space for shops.  The self sufficient design, NOAH, was created to complement New Orleans with a sustainable icon that could change the way the world looks at architecture.

Boston Arcology:

Radically conceived by E.Kevin Schopfer, AIA and RIBA, The Boston Arcology or simply put BOA, will be able to provide a safe living space to more than 15,000 people in a globally warmed world. Apart from normal living spaces, this floating wonder will provide ample space for hotels, offices, retail houses and museums, all on the surface of water. The floating city will also include a multitude of green spaces ranging from sky gardens to lush green lawns and gardens. The city is stated to be powered by renewable energy sources such as the wind and sunshine.

The Embassy of Drowned Nations:

Conceptualized by Oculus, the Embassy of Drowned Nations was adjudged one of the winners at the Sea Change 2030+ competition. The proposal is to develop a floating city in Fort Denison in Australia. The design, which is being referred to as a “blend of Atlantis and Eden”, will serve as a safe haven for anyone who would have lost their homes due to rising sea levels caused mainly due to global warming.  The unique inverted shape will ensure that it sinks deeper into water making the design stable and also exposing new land in the center of the mini city.

The Green Float:

The Green Float is the brainchild of a team of Japanese scientists and engineers. Essentially a floating city with all the features of any metropolis, the Green Float, which will be a carbon negative development, will also house the world’s tallest building with a conceived height of about 1000 meters. Though with today’s technology it would be difficult to even think about constructing such a tower, the design team hopes that by the year 2025 it might be possible to do so. The sustainable development which will include a “City in the Sky” will have residential units for about 30,000 people and also a waterside resort where townhouses will be built for about 10,000 inhabitants.

The Lilypad:

Put on paper by Vincent Callebaut architects, The Lilypad could well be one of the most beautiful floating city designs ever conceived. With an ability to provide sustainable living space to more than 50,000 inhabitants, this floating beauty is completely recyclable and powers itself with various forms of renewable energy. The design is so efficient that the architects state that it could even recycle CO2 and other forms of waste to produce something useful and green. The structure is designed to be covered in living walls and roofs with the top covered in grass and the center featuring a palm oasis.
