TetraPOT / Green sea defense design


Discipline: Professional Concept


Discipline: Professional Concept

TetraPOT is a sustainable sea defense system made of organic materials and plants. Distributing TetraPOTs along coastlines will eventually interlock to create a long-lasting sea defense of growing trees and roots that help keep the blocks in place. As plants grow inside out from TetraPOT, the roots will intertwine and gradually become a natural sea defense. The shape and placement will enable TetraPOTs to interlock with each other and form a structured web. The design not only prevents soil erosion, but also helps to protect and create a natural habitat. It’s not only a defense, but also an ecosystem. A home for other livings.

  • TARGET GROUPS Consumer / User, Trade / Industry, Public Sector / Government, Other target groups:: There is no actual target group of this project. Every thing is included e.g. nature, human, etc., Further specification:: It’s not only a defence, but also an ecosystem. A home for other livings.

  • TARGET REGIONS Africa, Asia, Australia/Oceania, Europe, North America, South America, Further localization:: Tropical and subtropical tidal areas where there are mangrove forests

  • DEVELOPMENT TIME up to 12 months

This concept is a future-looking sea defense system that uses living static and organic structures from the natural world. A symbiosis of stability and aesthetics, this 'win-win' concept demonstrates the synergies that arise from working together with nature instead of against it.
