I’ve learned a new architectural term today: bowellism, as a way of describing Richard Rogers’s tendency to turn buildings inside out, with their mechanics on the exterior. First used, apparently by Nikolaus Pevsner of a 1957 student project by Michael Webb, later a member of Archigram, for the Furniture Manufacturers Association in High Wycombe, which was described by Pevsner in a lecture on the return of historicism at the RIBA as looking ‘like a series of stomachs on a plate. Or bowels, connected by bits of bristle’. It was then adopted by Reyner Banham to describe an interest in visible circulation.
