The ‘Caldera’ Barrier Reef Masterplan
Hainan China - 2016
80% Ecology. A Coastal Defense that Grows over Time
The Caldera rethinks the coastal barrier island not as a defensive object, but as a living system. Instead of hard edges resisting the monsoon, the island absorbs and dissipates energy through wetlands, mangroves, and tidal landscapes.
This approach increases the island’s green coverage from a proposed 35% to over 80%, allowing it to function as both protection and restoration. The result is a coastal edge that grows stronger over time, not weaker.
A Self Seeding Spine that Sustains a Biosphere
At its core, a constructed “caldera” acts as a stabilizing armature—supporting energy, water, and waste systems that feed the surrounding landscape. Infrastructure is no longer separate from ecology; it becomes the catalyst for it.
Algae reactors, tidal energy, floating solar, and closed-loop water systems work together to produce energy while regenerating habitat. The island operates as a continuous exchange between human and natural systems, where each sustains the other.
