The Eden Project: The Biomes - Exterior/Landscape

With 1.956 million visitors in the first year of opening, the "biomes" at the Eden Project is one of the top attractions in the UK. This place houses the largest rainforest in captivity, stunning plants, exhibitions and stories that serve as a backdrop to the contemporary gardens, summer concerts and other events.

These rainforests live inside "biomes" which are placed in a sequence of 8 inter-linked geodesic transparent domes covering 2.2 hecatres, encapsulating vast humid tropic and warm temperate regions.
The biomes are structurally made of hex-tri-hex space frames that rely on 2 layers with the components made up of steel tubes and joints that are light and relatively small to be easily transportable. The cladding panel material are triple layered pillows of high performance ETFE foil.
