Coral reefs are highly susceptible to climate change and anthropogenic pressure. Specifically, overexploitation and artificial land expansion in the water can contribute significantly to coral reef degradation. However, water expansion is often necessary due to limited land resources for human habitation. This research follows the concept of “Living Architecture” to identify opportunities for integrating corals into the design of underwater structures, aiming to promote a symbiotic design approach that could support human and coral habitation in coral reef environments. The key findings identify opportunities for underwater planning by highlighting some of the environmental parameters that affect coral growth, such as wave energy, sedimentation, sunlight availability, and the correlation to reef zoning. Also, this research categorises the ecosystem services provided by corals that could be integrated into the design development. Furthermore, it generates a table of coral growth that aims to be used as a base for the design of bio-enhancing structures. The opportunities are summarised within the text through diagrams and tables, providing tools to aid the design process of underwater structures. This research prioritises the integration of corals as fundamental design elements, promoting nature-based solutions and sustainable development that adapts to the environment and addresses ecological and human needs.
