I walk a lot; the best way to experience a city. So it's sometimes to do with the way places join up. This cast concrete letterform is a part of the Lycée's gateway. Each of the form's facets arrives at a different character, so six possible letters come from each cast object. I've never been inside the Lycée but always walked through this way up to the V&A, in order to examine again and again how each form works. The surfaces set the tone for the V&A and its incredible Ceramics floor, a perennial inspiration.

The thing I love most about London is the juxtaposition of urban and rural, and nowhere is this better illustrated than in Lea Valley Park. A genuine wilderness where I’ve seen everything from ponies, to a rogue Costco outlet, and all less than 20 minutes from my front door.

The gallery was extended into a neighbouring Victorian House space about a year and a half ago, with a real skill in judging the meeting point between the contemporary and the conserved. The architects — 6a — were also responsible for Raven Row near Spitalfields (another favourite place). I'm lucky enough to work part of the week next door, at Camberwell College of Arts. This is about great food and good books. The café — a real haven at breakfast time before work — is run by the nicest team of people, with intertwined relationships to Camberwell. This book, designed by James Langdon, represents the kind of find possible in the bookshop and also the quality of conversation content had, over the best coffee.

The Greenwich Observatory with its green laser beam can transfigure any night sky. If you decide to cross the Thames via the foot tunnel, make sure you look out for the green ray. You can be on one side of the meridian in a minute, and cross to the other side on the next, without even realising it.

I spend many hours in the bookshops along this stretch, namely Henry Pordes for second hand books and new discounted titles (pile on left of photo), as well as Koenig Books for new art books with lots of great discounts in the basement. (photo right). In 2001 the rents for much of this strip were increased to align them closer to market value but thanks to public support they were reduced again. Unfortunately some bookshops still closed down; Koenig replaced the beloved Zwemmers - a real institution - but thankfully still provide great books, although others are no longer bookshops at all.
