New Addington-raised local legend John Grindrod is the author of Concretopia (a study of post-war architecture), the Wainwright Prize-nominated Outskirts (a personal account of the Green Belt and growing up on the edge of it). His latest, How To Love Brutalism, is about his admiration for the Marmite of architectural styles. He’ll be discussing this in his second visit to the Festival, after his hugely popular and entertaining appearance at our first.
