Sea Modules is the latest research chapter of Marie Griesmar body of work Beneath the Sea, which explores the fragile balance of coral reefs, and their morphological formations. At the intersection of art, science and architecture, her current reef prototype consists of easy-to-handle stackable bricks, 3D-printed from clay. Developed during her Fellowship at the Library Lab of the ETH Zurich, and at the Gramazio & Kohler Research Group, these structures provide ample sheltered spaces for settlement and growth of baby corals, and habitats for countless other reef animals. The bricks can be assembled in an infinite number of compositions, creating large reefs with customizable shapes.


This research became rrreefs a spin-off of the ETH Zurich. rrreefs stands for rethinking-rebuilding-regenerating coral reefs.
