“Open House Melbourne is an independent organisation that fosters public appreciation for architecture and public engagement in conversations about the future of our cities.”
Over the weekend of 29 & 30 July there are a lot of buildings open to the public and tours which are conducted. Most of the ticketed events are sold out, but there are many open places which don’t require tickets.
If you aren’t able to reserve a spot to some of the interesting/popular ones, you might end up just going to a bunch of architects studios to look at their little models and promo videos…which is underwhelming and has happened to me before.
