This project explores a new urban community deeply tied to Sargassum, a natural, carbon sequestering macro-algae that has grown uncontrollably in the Atlantic Ocean over the past decade. It is sourced before it reaches the Caribbean shores, after which it is processed to create raw material for construction. The sargassum based material offers low embodied carbon along with opportunities to experiment with load bearing masonry construction. After agreeing upon a localized building and ethical framework, members are given the freedom to build on their own, resulting in a ground up, iterative approach that explores new ways of living in an eco-based urbanism.
