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.

One of my favourite things about London is the underground transport system itself. I love the design of the information systems and the stations have so much history — some of them dating right back to the 1800s.

London has great green spaces. There are large royal parks and small public gardens, hidden allotments and roof terraces. Each one has its own identity and characteristics and everyone has their favourite. In summer they become extensions of people homes, you see girls sunbathing from 9 am and the endless picnics mean you can eat 3 meals a day in the park. My favourites - St James Piccadilly Gardens, Hyde Park, Barbican Conservatory.

2 Willow Road designed by Ernő Goldfinger and completed in 1939. It has been managed by the National Trust and is open to the public. Goldfinger lived here with his wife and their children until his death in 1987.

I love this space.
