Gyaros presents a complex condition shaped by ecological fragility, limited resources, climatic exposure, and the historical legacy of political exile. One of the project’s central challenges was developing a framework capable of supporting environmental regeneration and public engagement while preserving the island’s sensitive landscapes and cultural significance. The proposal responds through a closed-loop metabolic system integrating desalination, soil regeneration, renewable micro-grids, agroforestry, biodiversity corridors, and circular water management into a continuous environmental network. Implemented through three phases, the strategy evolves from pioneer planting and soil stabilization toward diversified agro-ecological systems and community-led stewardship. The project retains the raw Cycladic character of the island while introducing productive terraces, aromatic landscapes, ecological corridors, and research infrastructures that connect the five bays. At Bay 4, the restored prison complex becomes the Museum and Laboratory Center, operating as a threshold between memory and regeneration through laboratories, workshops, exhibition spaces, and collective gathering areas sheltered beneath solar-tiled roofs. Rather than separating conservation from inhabitation, the proposal treats ecology, infrastructure, and memory as interdependent territorial systems.
