Nexus is an immersive museum that bridges Savannah’s past, present, and potential futures. Set within the historic Old Waterworks building, this adaptive reuse project transforms a site tied to water into a powerful space for climate awareness. The museum explores rising sea levels and their cultural, ecological, and social impacts. Through immersive and experiential design, it transforms visitors into engaged citizens. Visitors experience destructive and regenerative futures, engage with interactive tools, and leave with collective actions -bridging history, sustainability, and resilience.
