Eden Project biomes Cornwall

Cornwall, England · 2000-2001 · Not readily available

The judgement call

Account-gated at launch

Biomimicry in design: The honeycomb shape of the biomes maximizes strength while minimizing materials. - ETFE cladding: The use of ETFE (ethylene tetrafluoroethylene) for the inflated cells provided a lightweight, transparent, and durable solution. - Site transformation: Converting an almost uninhabitable clay pit into a new natural habitat. - Efficiency in design: The biomes were designed for efficiency in both space and material usage.

Key engineering challenges

Building within challenging terrain (a former clay pit). - Designing and constructing the large-span geodesic domes with minimal materials. - Developing a lightweight and transparent cladding system (ETFE). - Complex ground modelling and site remediation.
