The Core is the latest addition to the site and opened in September 2005. It provides the Eden Project with an education facility, incorporating classrooms and exhibition spaces designed to help communicate Eden's central message about the relationship between people and plants. Accordingly, the building has taken its inspiration from plants, most noticeable in the form of the soaring timber roof, which gives the building its distinctive shape.

Grimshaw developed the geometry of the copper-clad roof in collaboration with a sculptor, Peter Randall-Page, and Mike Purvis of structural engineers [[Sinclair Knight Merz|SKM Anthony Hunts]]. It is derived from [[phyllotaxis]], which is the mathematical basis for nearly all plant growth; the "opposing spirals" found in many plants such as the seeds in a sunflower's head, [[pine cone]]s, and [[pineapple]]s. The copper was obtained from traceable sources, and the Eden Project is working with [[Rio Tinto (corporation)|Rio Tinto]] to explore the possibility of encouraging further traceable supply routes for metals, which would enable users to avoid metals mined unethically. The services and [[acoustics|acoustic]], mechanical, and electrical engineering design was carried out by [[Buro Happold]].

The Core is also home to art exhibitions throughout the year. A permanent installation entitled ''Seed'', by [[Peter Randall-Page]], occupies the anteroom. ''Seed'' is a large, 70 tonne egg-shaped installation, carved from a single block  of [[granite]] from [[De Lank Quarries|De Lank Quarry]] on [[Bodmin Moor]], standing some {{convert|13|ft}} tall and displaying a complex pattern of protrusions that are based upon the [[Fibonacci number#Nature|geometric and mathematical principles that underlie plant growth]].<ref>{{cite news |title= Granite seed is 'planted' at Eden |work=[[BBC News]] |date= 11 June 2007 |url= http://news.bbc.co.uk/1/hi/england/cornwall/6738783.stm |access-date= 25 February 2018}}</ref><ref>{{cite web |url= http://www.edenproject.com/visit/whats-here/seed-sculpture |title= Seed sculpture by Peter Randall-Page |publisher= Eden Project |access-date= 25 February 2018 |quote= Made out of a single piece of granite, its surface has been carved with 1,800 nodes in the pattern of a Fibonacci spiral – the growth pattern found across the natural world in things like sunflowers, pine cones and ammonites}}</ref>
