Come and participate in this event and explore some of the city’s best architectural accomplishments. If you love history, architecture, and design, you’ll love the Sydney Open!

Welcome to a refreshed Sydney Open – the city’s leading event for architecture, design and the built environment. We asked our visitors, members, volunteers and industry colleagues what they’d like to see for the Sydney Open. You’ve spoken; we’ve heard you. You’ll discover a new annual offer of in-depth curated experiences and stories from the architects, designers and heritage experts connected to each site.

Held over several Sundays throughout 2025–26, this carefully curated program opens the doors to select buildings under key themes, including Adaptive Reuse, among many more. The revamped program makes Sydney Open more enjoyable, allowing visitors to engage with unique spaces throughout the year.

Designed to be viewed over the day, each Sydney Open event also unlocks so much more: a rare opportunity to hear fascinating insights and captivating stories from those ‘in the know’—global leaders in architecture, design, and placemaking, academics, and arts and culture experts.

Enjoy immersive experiences that peel back the layers to reveal the personalities, innovations, and historical contexts that brought these unique environments to life. These will give you a broader understanding and knowledge of our city’s architecture, history, and design.
