The world’s first floating city will be here in 2025

I, for one, can’t wait.

The world’s first floating city, to be built off the coast of South Korea, is expected to be finished by 2025. The city, backed by the United Nations, will be built off the coast of Busan in order to combat rising sea levels. It will be a “flood-proof infrastructure,” according to the project leaders, consisting of many man-made islands that will rise with the sea to eliminate the possibility of flooding.


The details

The self-sufficient city, which is a collaboration between Oceanix and the United Nations Human Settlement Program (UN-Habit), will generate its own electricity from solar panels, produce its own food and fresh water, and ferry tourists and residents between the island on specially-made boats.


According to local estimates, the city would be 75 hectares in size and house 10,000 people. The neighborhoods will be arranged into six clusters around a central harbor that will be protected. This means that each hamlet might have a population of up to 1,650 people.


Floods, tsunamis, and Category 5 hurricanes will all be natural disasters that the city will be built to resist. That’s not all, though. The city will be built in such a way that it will dynamically expand, evolve, and adapt over time.


Construction on the project, which is expected to cost $200 million, will begin soon. The “historic agreement” has already been signed by the Republic of Korea’s Busan Metropolitan City, UN-Habitat, and New York designers Oceanix.


The co-founder of Oceanix, Itai Madamombe, shared:


“It just happened that Busan is the best place for us to deploy this prototype. But this is something that we hope will be useful to all coastal cities around the world, and all coastal communities who are facing the challenge of sea-level rise.”


To meet the needs of the community, Oceanix will cooperate with local designers and the work’s findings will be presented at a UN panel in April. Maimunah Mohd Sharif, the executive director of UN-Habitat said: “We look forward to developing climate adaptation and nature-based solutions through the floating city concept, and Busan is the ideal choice to deploy the prototype.”


The design

The floating metropolis of Oceanix City is essentially a cluster of hexagonal platforms floating in the ocean. Hexagons are often regarded as one of the most efficient architectural designs, allowing architects to save both space and material. Consider the neatness of a beehive’s interior, which is effectively a web of interlocking hexagons.


A limestone coating two to three times tougher than concrete would be applied on the city’s platforms. Underwater minerals are exposed to an electric current to form the substance. It becomes stronger over time and can repair itself in the presence of that current, allowing it to resist extreme weather conditions.


With all the advancements in technology this decade is experiencing, this surely is one of the coolest inventions yet. Doesn’t this beat a NFT design space in the Metaverse?
