The Eden Project in Cornwall is the largest botanical garden of this kind up to now: it provides a habitat for trees and plants from three different climatic zones.
The domes, with a miximum span of 124m, are located in a disused quarry. The geodesic domes are lightweight, prefabricated and delivered on site as small components.
The dome construction consists of two layers: the outer skin is based on a hexagonal layer, the inner on a triangular and hexagonal grid. Both layers are interconnected by steel compression elements in a pyramidal configuration.
The covering consists of ETFE cushions.
