Jonathan O’Dea creates abstract sculptures out of waste material from construction sites. In so doing, he makes art in a sustainable way. In this episode, he talks about his Irish background in which he was making objects from an early age, how working on building sites as a young man inspired his future art, how he discovered sculpture after studying painting at Central St Martins, the kind of materials he takes from construction sites such as Crossrail and the Olympic Park, how he puts them to use in his sculptures and how his artworks offer a metaphor for the human condition.
