Building designer Thomas Heatherwick is best known for his work on landmarks such as New York's Vessel and Little Island, and designing the cauldron for the Olympic flame at the 2012 games in London. The founder and design director at Heatherwick Studio tells Bloomberg's Stephen Carroll that Vessel will re-open to the public this year, and how he'd like to be involved in designing social housing in the UK. See omnystudio.com/listener for privacy information.
