According to forecasts, by 2050, 90% of the world's largest cities will face the problem of rising sea levels. Coastal erosion and flooding will make millions of people refugees, and destroy homes and infrastructure. The solution would be Oceanix, an environmentally friendly, climate-resilient city, a modular, self-contained structure that can expand indefinitely. BIG architects developed the first version of such a settlement for the tropics and subtropics as the most vulnerable part of the planet, but such cities can be created, for example, in Northern Europe.
The module is a two-hectare block with housing, workplaces and public spaces for 300 people. All structures will be below seven stories to withstand wind loads and maintain a low center of gravity. Wide roofs will shade facades and spaces around buildings, saving energy for cooling rooms, and at the same time maximizing space for solar panels. Residents will provide themselves with food and reduce waste through communal surface farms and breeding under the floating platforms of their neighborhood on the reefs from
"Bioscal rocks" of algae, oysters and other molluscs, which will also purify water and accelerate the regeneration of ecosystems.
Six such neighborhoods can be connected around a common central harbor, and the resulting settlement of 1,650 inhabitants (12 hectares) could become one-sixth of a city per 10,000 inhabitants. In such larger formations, a varied public, commercial, cultural and leisure program is provided; residents can move on foot or by watercraft, including electric ones. Particular attention is paid to the preservation of the identity of such settlements. They will be built from local materials, for example, bamboo, which is six times stronger in tensile strength than steel and has a negative carbon footprint: it grows very quickly, and it can be grown directly on floating platforms.
Oceanix-style cities can be constructed onshore and towed to the final “anchorage” site. Low rents on water surfaces also make them an affordable housing option for coastal metropolitan areas, where they can be quickly shipped to fill housing shortages.
