Interior designer Mary Featherston is famous for many things. Her trailblazing creations with her late husband Grant Featherston. Their extraordinary Melbourne house designed by the iconic modernist architect Robin Boyd, which has housed four generations of their family. But what Mary's most driven by is her 50-year mission to change the face, feel, and function of Australian classrooms. Classrooms, not just teachers, can be educators too! She joins Big Ideas' host Natasha Mitchell.
