Inside a large warehouse in an unremarkable industrial street in north London, something unexpected is happening. In contrast to the grimy buildings outside, I walk into a verdant garden-of-Eden landscape, backed by a giant photo of planet Earth. Then I pass a patch of scrabbly, log-strewn red-earth desert.

These living worlds-within-worlds are photographic sets, days in the making, now awaiting the scrutiny of a snapper’s lens.
