Prior to his artist talk at the Hammer Museum last week, nearing the culmination of his massively successful "Provocations" show, Thomas Heatherwick spoke with Paul and Amelia about his firm's personality and design approach. We discuss his interview on this week's single-focus episode, touching on his diverse project list, his "doubting Thomas" identity, and his attitudes towards "franchised" architecture.

If you're in Los Angeles, "Provocations" will be at the Hammer Museum through May 24. To hear more about the exhibition, listen to our conversation with curator Brooke Hodge, featured on "Three Funerals and a Curator".
