If there were an olympic league table for design, Britain would be right at the top. Since the Second World War, British designers have revolutionised our homes, our workplaces, our roads and our public institutions. In November the Design Museum opens its new £83m home in Kensington. To mark this great moment for British design, BBC Arts profiles ten great living British designers. Arts reporter Brenda Emmanus meets and profiles our 'Top 10', to find out what inspires them to make such phenomenal objects. She reveals how designers have responded to society's evolving tastes, from the brash 60s modernism of Margaret Calvert's road signs through to the colourful technology of Rick Dickinson's ZX Spectrum. She also meets Britain's most prolific designer, Sir Kenneth Grange (Intercity 125, bus shelters, the Kenwood Chef...), as well as Andrew Ritchie, who gave the world the Brompton Bike.
