 Breezeblocks have historically been made from concrete, clay, or mud. They have been popular in tropical and subtropical climates where a combination of ventilation and privacy are valued. Breezeblocks have appeared in Brisbane architecture over the decades. A search of the 61,000 images comprising the Frank and Eunice Corley Collection Corley Explorer (slq.qld.gov.au) held by the SLQ returns a total of 387 images tagged with the term ‘Breezeblocks’. The photographs were taken by the Corleys all around Queensland during the 1960s–70s.  Breezeblocks have historically been made from concrete, clay, or mud.

 All inside faces of the block will be formed against XPS foam inserts or cores. You will receive instruction on how to cut the foam using a hot wire. Because the XPS foam sheets are not readily available in a thickness corresponding to the full depth of a breezeblock, you will need to glue 2 or 3 thicknesses in a sandwich.  All inside faces of the block will be formed against XPS foam inserts or cores.

We acknowledge Aboriginal and Torres Strait Islander peoples and their continuing connection to land and as custodians of stories for millennia. We are inspired by this tradition in our work to share and preserve Queensland's memory for future generations.
