Renzo Piano

As part of its twentieth anniversary, HARDtalk takes another look at its 2013 interview with the designer of one of London's newest and most controversial buildings - The Shard. Renzo Piano is one of the world's most accomplished and feted architects; and one used to dividing opinion. Back in the 1970s he designed Paris' Pompidou Centre and since then has taken on high profile developments all over the globe. His London creation is already loved, but it is also loathed. What does The Shard say about us? And why build it so big?
