Drummoyne Granny Flats Built Around Your Property
Drummoyne features established Federation and interwar homes on generous blocks, many exceeding 500 square metres with deep backyards.

Whether you need a compact studio, a one bedroom retreat or a full two bedroom dwelling, we deliver designs that complement established Inner West properties.
The Drummoyne property market remains strong with median house prices exceeding $2.5 million, making granny flats a smart investment for homeowners.
