Campsie Granny Flats Built Around Your Property
Campsie features predominantly brick homes built from the 1950s through to the 1980s, with typical block sizes ranging from 450 to 650 square metres.

Our deep knowledge of Canterbury Bankstown Council requirements ensures smooth approvals for studio, one bedroom and two bedroom designs.

Campsie’s property market remains strong due to excellent train access to the CBD and proximity to major employment hubs across Western Sydney.
