If you haven’t visited the Eden Project in Cornwall yet, start here. The vision of Tim Smit and his team “to build a place unlike any other, one that would capture the imagination of all who came upon it” is laid bare in Eden, Smit’s handsome full-colour account of the recreation of the world’s environments in climate-controlled biomes.

From the seeds sown by Smit’s work on the Lost Gardens of Heligan and his discovery of the perfect site in Bodelva, a disused china clay pit, he traces the sometimes perilous path to opening day in May 2000.

Eden now employs more than 500 staff, but Smit’s account with its emphasis on attracting key individuals has much to offer anyone who’s tried to make anything happen on a smaller scale. And one of his chapter titles, “If you’re not on the edge, you’re taking up too much space”, might look good on the staffroom wall.

Friday magazine has five copies of Smit’s book, publised by Bantam Press and worth pound;25, to offer readers. Write your name and address on a postcard and send it before May 24 to: Eden offer, Tracey Thomas, Friday magazine, 66-68 East Smithfield, London E1W 1BX.* Take the biscuit
