"One of the architects behind London's famous Gherkin skyscraper has now turned against glass buildings. Is it time tall towers were made out of something else, asks Hannah Sander.
It is one of the UK's most recognisable buildings. A Stirling Prize winner. A backdrop to Hollywood films. Named the most admired tower in the world.
