Nature has always been a source of inspiration for designers – plant and animal forms, in particular. Think of the organic skeletal shapes of Santiago Calatrava’s bridges, the swirling naturalism of William Morris patterns, or Arne Jacobsen’s Swan and Egg chairs.

But cityscapes throw up surprising riches. This photograph, taken in King’s Cross station when it was recently being revamped, is by my daughter. The peeled wall, with its smeared colours and vestiges of lettering, is really pleasing to me.
