This paper and talk document my collaboration with Jolyon Brewis of Grimshaw Architects on the design of a new education building for the Eden Project, Cornwall. The roof structure of the building is based on plant geometry in the form of spiral phyllotaxis and incorporates a granite sculpture which will be sited in it's own specially designed chamber at the centre of the building. This very large sculpture is based on the same growth pattern as the roof and has involved collaboration with professionals from many disciplines including quarrymen, stone masons, engineers and computer experts.
