Short summary
Summer Islam (Material Cultures, London), Corentin Dalon (Bento, Brussels) and Emma van der Leest (Blue City Lab, Rotterdam) on the labour, cost and aesthetical language of building with natural materials.
Introduction text
The second episode turns to bio-based and grown materials — mycelium, algae, bacterial cellulose — and to the gap between a beautiful prototype and something people can actually build with. Host Hülya Ertas speaks with Summer Islam, co-founder of Material Cultures in London; Corentin Dalon, co-founder of Bento in Brussels, who realised the Belgian Pavilion at the 2023 Venice Architecture Biennale in raw earth and mycelium; and Emma van der Leest, founder of Blue City Lab in Rotterdam, who grows materials from bacteria, fungi and algae rather than extracting them.
The conversation moves from the physical toll that supposedly 'traditional' techniques such as stone masonry or reed thatching place on workers' bodies, to the debates around stabilising and industrialising earth construction, to the marketing problem of biomaterials that keep being compared to the animal- or oil-based products they are meant to replace: a mycelium 'leather', a seaweed-based 'linoleum'. Along the way: a student project in Benin that started from local earth rather than a floor plan, a jacket grown from bacterial cellulose that can never be washed, and a shared reading list running from Roland Barthes' Mythologies to David Graeber and David Wengrow's The Dawn of Everything.
