The Reef Architecture project aims to demonstrate the positive transformative power for the activation of latent eco-systemic feedback processes in Miami through the creation of underwater protection sea barriers generated with digitally simulated growth processes. It thrives on the potential that emerges from a coherent utilization of the environment’s inherent ecology for its own transformation and evolution, using an approach based on computationally simulated ecosystems and enabled by the possibilities of large-scale 3D concrete printing technology.
