The Parcels Post Office is an integral part of the historic Central Railyards Precinct and was originally designed as a four-storey Georgian-style building. To add a tower above the heritage building without being overbearing or diminishing of its character, a design strategy utilising the concave and convex curves of the historic design was employed.

A cluster of ‘pill’ shaped forms complement the heritage building’s curved corners, creating slender vertical proportions while reducing visual bulk. This cluster of forms respond to the functions and recall the shape of indigenous message sticks.

Referencing the craft and materiality of the original Parcels Post Office, a contemporary interpretation pairs concave terracotta fins to create a human scale grid, visually uniting the various tower functions and providing passive shading and insulation.
