Hanna Harris is Helsinki’s chief design officer and the second person in the job since the role was created in 2016. But why does a city need a chief design officer? And, what can design do to boost wellbeing? Erika Benke joins Hanna as she searches for new pioneering opportunities that have the potential to change people’s lives. They visit a vast decommissioned power plant, inviting local people to share their views on how to give an industrial facility that has served its purpose, a new lease of life. They also go to an old playground that is about to be transformed into a new themed playground where children can learn about computing, algorithms and AI. As Hanna travels a cross the city, we hear her plotting, planning and exploring ideas and infecting others with her passion for design.
