This research project presents an alternative approach to addressing the complex challenges of sustainability of the coastlines by integrating advanced technology solutions with ecological conservation principles. The paper intro-duces the Ecoblox, a modular infrastructure system consisting of interlocking blocks devised for attachment to seawalls to improve marine biodiversity at the water edge. The design of the Ecoblox system employs environmental data, data analytics, AI-powered generative algorithms, and digital fabrication to produce blocks with complex shapes and textures suitable for bio-marine habitats. The project is executed in two phases. This paper describes the initial phase, encompassing the prototyping process, construction, testing, and analysis of various Ecoblox versions. The primary objective of this phase is to assess multiple designs and evaluate their effects on biodiversity. Building upon the insights gained from the initial phase, Phase II of the study focuses on developing data-driven strategies and applying robotic 3D printing to refine the system’s design and construction.
