What if the spaces we inhabit every day—homes, hospitals, workplaces—are shaping us more than we realise? In this thought-provoking talk, Dr Sarah Green explores how physical and digital environments impact our mood, behaviour, and well-being. From childhood dens to post-Covid workspaces, from beach holidays to hospital waiting rooms, space is never neutral. It whispers, nudges—and sometimes shouts. With insights from design thinking and spatial philosophy, this talk invites us to see space as a co-author in our lives. If we shape it with empathy and intention, we can transform not just how spaces look—but how they make us feel.
