‘PS: Potential Spaces’ is a collaboration between three disciplines – law, architecture and art – with Chalk Horse collective and Freehills Lawyers. The installation makes apparent the ‘invisible’ legal framework of Tank Stream Way, making reference to historical records such as property and planning boundaries, written descriptions and paintings of the area – originally a fresh water stream over which the street was built. This information is translated directly onto the laneway via survey using custom bronze markers, road paint, and weighted ropes representing a plumb bob and string. Temporary street furnishings are deployed as an indication of possible future habitation with standard council planter boxes appropriated as street lounges.
