Clerkenwell in central London has long been a creative industry enclave. Renowned for clock-making since the early 18th century, it is a place where other old-world trades, including printing, bookbinding and jewellery-making, still flourish. More than 200 architecture practices and 80-plus contemporary furniture showrooms are based in Clerkenwell — there is a higher density of creative businesses here than in any other part of London. This ensures that Clerkenwell Design Week, an annual event of exhibitions, workshops and talks, held this year from May 24 to 26, feels like part of the area and not something grafted on.
