ZHA’s Marine Habitats

Unveiled at the World Design Congress 2025, Nereid by Zaha Hadid Architects (ZHA)

Nereid, conceived as a digitally fabricated marine habitat focuses on regenerating food resources by encouraging the growth of phytoplankton and filter-feeding shellfish—the foundational species of marine food chains. By reintroducing habitats for these species, the project aims to repair broken links in the ecosystem, creating a ripple effect that benefits fish populations, biodiversity, and ultimately, human food security.

Fabricated using large-scale 3D printing by D-Shape, Nereid employs pH-neutral, low-carbon concrete pastes to produce complex, porous geometries. These forms mimic the structures of kelp forests, benthic substrates, and coral reefs, creating safe havens for marine organisms while allowing water to flow naturally through them. Beyond nurturing life, the habitats act as barriers against destructive fishing practices such as bottom trawling.

Developed in collaboration with marine physiologist and toxicologist James Fang (Hong Kong Polytechnic University), the project links architecture and marine science to promote ocean health and seafood sustainability. Fang’s research underpins Nereid’s role as a prototype response to biodiversity loss caused by climate change, urbanisation, land reclamation, and pollution, all of which increasingly threaten coastal ecosystems.

Set for deployment in Hong Kong’s North Lantau Marine Park, Nereid demonstrates how digital fabrication can move beyond buildings to foster ecological repair.
