Quentin Blake and a team of architects, artists, designers, cartoonists and illustrators will lead visitors in exploring and drawing around the extraordinary architecture and spaces at Somerset House and King's College, London. Join them drawing inside, outside, what's above and below the space and everything in between, absolutely free.

The event starts at 10.30am on Sunday September 24 with Lord Foster kicking things off with a talk at 11am.

Activities and events will run all day and are open to all ages. Places on some of them will be allocated on a first-come-first-serve basis.
