RE:Form is an artificial reef system designed to support coral growth while reducing environmental impact. Instead of concrete, it uses naturally textured volcanic rocks that are water-jet cut into modular, interlocking forms. These pieces fit securely on the seabed, creating stable microhabitats for coral larvae and marine species. The system is lightweight, adaptable to different coastal conditions, and entirely zero-waste. By combining natural materials with precise fabrication, the design offers a gentle, environmentally responsible approach to restoring marine ecosystems and enhancing biodiversity.
