The visionary beekeeper started his first beehive ten years ago on the roof of his tower block in Bermondsey and today runs 30 sites across the city. His bees live atop Tate Modern and Tate Britain, Fortnum & Mason and the National Portrait Gallery, and he supplies honey to the Savoy tearooms, Harvey Nichols and Harrods. His bees forage in parks, cemeteries, along railway lines and in windowboxes, and because of the diversity of the plants and trees in the city, produce far richer honey and greater yields than they would in rural areas.
