SKYWALK CITY: The Unsinkable Resilient City----A Three-Dimensional Urban Design for Typhoon, Flood, and Sea-Level Rise Adaptation Based on Macau's Reclaimed Land

Set in Macau’s reclaimed Zone H, this project envisions Skywalk City—a resilient and adaptive urban prototype designed to address the growing risks of flooding, typhoons, and long-term sea level rise. At the heart of the design lies the Skywalk System, a modular elevated pedestrian infrastructure lifted to the third floor level. More than a circulation network, Skywalk functions as a multifunctional urban backbone, integrating daily mobility, emergency evacuation, logistics, and commercial activities within a climate-resilient spatial framework. Its components—such as sky stations, observation decks, and drone delivery nodes—can be prefabricated, rapidly deployed, and flexibly reconfigured. The system also anticipates future elevation needs, enabling phased vertical upgrades in response to rising ground levels without disrupting urban operation. Complementing this is a coastal ecological buffer composed of modular breakwaters and mangrove habitats, which collectively reduce storm surge energy while supporting biodiversity. Inland, amphibious and floating housing models populate mid-density zones, demonstrating adaptive living solutions for flood-prone areas. Together, these layered systems form a comprehensive resilience strategy that blends engineered robustness with ecological intelligence—offering a forward-looking urban model that is scalable, sustainable, and prepared for the climate challenges of tomorrow.
