The Garden Museum and the Garden Museum Cafe are a welcome addition to an area of London that is slow to change. The food at the cafe is modern and seasonal, and the space is beautiful and looks out into a small garden by Dan Pearson. Christopher Woodward, the museum director, is active in improving and campaigning for local green spaces and creating space for the local community. The Museum lives inside an old 18th-century church and has a changing program of exhibits. Worth noting, it is a museum on the subject of gardening, not of gardens, so don’t expect many flower beds. Throughout the summer holidays, the Museum has lots of great events for kids, including cooking and drawing. Luke and I also designed the identity for the museum… the tote bags and visitor badges are particularly nice.

This uninspiring sounding place is a disused railway line that runs along the roofline from Finsbury Park to Highgate. A great place to excerise and escape.

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.

My friend Guillaume opened the swankiest rooftop in London that still feels like a house party. Louie is a French-Creole restaurant, live jazz music venue and oyster bar too.

A special place, a shop which is like a museum, worth popping in to feel the humanness and heritage of London. And if you are looking for rope, compass or any sailing supplies, this is the place. There is no shop like it.
