Bjarke Ingels is the Danish architect who is responsible for creating the flood defence project for Manhattan. In 2012 Hurricane Sandy saw flood water rise up to 2.4 metres. Lives were lost, the city’s transportation system was brought to a stand-still and the New York Stock exchange was closed for two days. As a child, Bjarke wanted to draw comic books and walk on roofs and the buildings that he’s designed include a power station with a ski slope. How can he build his sense of fun and creativity into vital protection against climate change? Razia Iqbal meets Bjarke for The Cultural Frontline on the BBC World Service.
