BIG unveils a sustainable floating city in response to rising sea levels
BIG and a coalition of partners have unveiled Oceanix City, a visionary proposal for the world’s first resilient and sustainable floating community for 10,000 people. Presented at the first UN high-level roundtable on Sustainable Floating Cities, the conceptual design was created as a potential solution to the perceived threat of climate change and rising sea levels. Conceived as a “modular maritime metropolis,” Oceanix City is engineered for self-sufficiency with features from net-zero energy and zero-waste systems to a sharing culture.
According to UN-Habitat, 90 percent of the world’s largest cities will be exposed to rising seas by 2050. As part of UN-Habitat’s New Urban Agenda, BIG teamed up with MIT Center for Ocean Engineering, Mobility in Chain, Sherwood Design Engineers, Center for Zero Waste Design and other partners to propose Oceanix City. This is a 75-hectare floating city that is meant to grow and adapt organically over time — from neighborhoods to cities — with the possibility of scaling indefinitely. To that end, Oceanix City uses a modular design with two-hectare modules serving mixed-use communities of up to 300 residents centered on communal farming.
Larger 12-hectare villages comprise six neighborhood modules clustered around a protected central harbor accommodating social, recreational and commercial functions for up to 1,650 residents. For a city of 10,000 residents, six villages are connected around a larger protected harbor. Construction materials will be locally sourced whenever possible, and components would be prefabricated on shore and then towed to their final site to keep construction costs low and thus permit affordable housing.
“The sea is our fate — it may also be our future,” Bjarke Ingels said. “The first sustainable and self-sustained floating community, Oceanix City, is designed as a human made ecosystem channeling circular flows of energy, water, food and waste. Oceanix City is a blueprint for a modular maritime metropolis anchored in the UN’s Sustainable Development Goals. The additive architecture can grow, transform and adapt organically over time, evolving from a neighborhood of 300 residents to a city of 10,000 — with the possibility of scaling indefinitely to provide thriving nautical communities for people who care about each other and our planet.”
