Kengo Kuma is a mercurial architect, who works with natural forms and historical structures with an avant-garde sensibility. Tim talks to the usually taciturn Japanese maestro about the horrors of Metabolism, what he calls the philosophy of the detail and the affinities between Portugal and Japan.

To celebrate the London Festival of Architecture’s 20th anniversary Tim met Edwin Heathcote, the Financial Times architecture critic, in a small podcast booth built underneath the Lloyd’s building in London.

Job Floris was an editor of the pioneering, always interesting OASE Journal for Architecture from 2008 until 2018. He is also an architect: one half of the Rotterdam-based practice Monadnock which he founded in the naughties with Sandor Naus. For reasons that Tim explores with Job, Monadnock’s work sits uneasily in their home city although it is popular elsewhere in the Netherlands and in Germany.

Bijoy Jain lives in Mumbai; the city of his birth. Tim talked to him about his world famous practice Studio Mumbai which sits between the world of art, craft and architecture and is staffed by skilled craftsmen, technicians and draughtsmen, who design and build each project themselves. He reflects on architecture as dance and his time living and working in London.

Simon Henley is one of London architecture’s unsung heroes. His practice Henley Halebrown wrings great buildings from unlikely sites across the city, Hackney New Primary School being a great example but also their latest work Thames Christian School. But Simon is also a great advocate for the culture of architecture as a writer but in a host of other ways. Tim talked to him about buildings, history and London.

This is the second half of a conversation between host Tim Abrahams and William Mann the first half of which was broadcast earlier in this series. This week the practice William is a partner of Witherford Watson Mann will complete their extension to Clare College in Cambridge. This is a discussion about that building but much more. Moliere, Freud and Imannuel Kant.
