What should cultural heritage encompass? What should be protected—how and why? Spring evening design debates with the Australian Institute of Architects returned to MPavilion during our most recent season of free events. Representatives from the Victorian Chapter of the AIA went head to head on timely and enduring ideas in architecture, including this debate, titled ‘New heritage’. Panellists included Sofie Kvist, Matt Gibson, Tania Davidge, Ross Turnbull and Clare Cousins.
