Bangkok-based architecture firm S+PBA recently unveiled plans for a self-sustaining floating city that can thrive with the ebb and flow of rising tides. Dubbed “A Post Diluvian Future”, the “wetropolis” allows Bangkok to live with natural flooding instead of resisting it while creating a homeostasis that detoxifies the region’s polluted waters.

Embracing the water, they call their new Waterworld-style city plan a “Wetropolis.” The vegetation basis for the Wetropolis is a forest of indigenous mangroves, which the government is already trying to implement in Bangkok. The mangroves naturally filter water, and they also supply fresh oxygen and natural cooling.
