Visitors to this year’s London design festival can expect to see everything from an installation inspired by Barbie’s Dreamhouse to an exhibition devoted to the late furniture designer Robin Day.

At the Yorkton Workshops in Hackney, east London, however, the cutting-edge show features clothes pegs, hammers, smart cards and a case for carrying Pringles crisps.
