expressions of interest are now open
We are seeking iconic and interesting buildings to open their doors for Sydney Open on Sunday 2 November. You will join a carefully curated program of buildings and spaces recognised for their significance in the city's architectural landscape, and welcome new audiences to your space.
As one of Australia's foremost curated architectural programs, Sydney Open relies on the generous involvement of building owners and stakeholders like you. Partner with Museums of History NSW and align with leaders in architecture, design innovation, sustainability, history and heritage.
The Sydney Open program runs from 9am to 4pm, offering ticketholders a 'choose your own adventure' experience as they explore buildings and spaces that are usually off limits to the public.
Let us put your building on the Sydney Open 2025 map!
