2026 Sustainability Summit Keynote preview: Design for Climate, Design for Change

The Summit forms part of the 20^th-anniversary Sustainability Awards program and brings together leading voices in sustainable architecture, design, and construction for a day of CPD-accredited discussion and debate.

Representing a new generation of architects focused on practical, climate-responsive design, Marra has built her practice around one pressing question: how can buildings respond intelligently to a changing climate without increasing reliance on energy-intensive technologies?

Her work investigates the realities facing Australia’s built environment, from rising temperatures and extreme winds to bushfires and flooding. Rather than relying on mechanical solutions, Marra explores how architecture itself can provide resilience through thoughtful planning, material selection and environmental responsiveness.

Central to her research is a deep appreciation of traditional building practices from across the Asia-Pacific region. By examining historical precedents through the lens of contemporary knowledge and technology, she demonstrates how time-tested principles can be adapted to meet today’s climate challenges while maintaining comfort, functionality and amenity.

Marra’s keynote will present a compelling case for architecture that works with climate rather than against it. Through research and practical case studies, she will illustrate how place-based design can reduce environmental impact while creating buildings that are more robust, adaptable and liveable.

As the built environment faces mounting pressure to respond to accelerating climate change, Marra’s presentation promises to deliver valuable insights for architects, designers and industry professionals seeking practical pathways towards a more resilient future. It is a timely reminder that some of the most effective innovations are grounded not in complexity, but in a deeper understanding of climate, place and the enduring lessons of the past.
