A granny flat builder in Auburn works with a well-connected suburb where the zoning cuts two ways. On the R3 and R4 land near the CBD a townhouse or unit scheme is often the higher use, but on the R2 and R3 house blocks a granny flat stacks up well. The 450 to 650m² lots mostly clear the 450m² threshold for a 60m² secondary dwelling under the Housing SEPP, and proximity to Olympic Park, Silverwater and the station gives a deep worker tenant pool.
The ground is moderately reactive clay, so the slab is engineered off geotech to suit. The 1930s to 1970s stock — pre-war cottages and post-war fibro — usually carries asbestos, so a licensed strip-out comes first where demolition is involved.
What I check first on your Auburn block: the zoning, whether the survey clears 450m² for the CDC path, and the slab off geotech. Near the CBD the zoning can point to medium density instead.

Zoning cuts two ways
On Auburn's R3 and R4 land near the CBD, a townhouse or unit scheme is often the higher use than a granny flat.
On the R2 and R3 house blocks — mostly 450 to 650m² clearing the 450m² Housing SEPP threshold — a 60m² secondary dwelling stacks up, with Olympic Park and Silverwater workers driving the rental.
Reactive clay and pre-war stock
The moderately reactive clay means the slab is engineered off geotech to suit.
The 1930s to 1970s cottages and fibro homes usually carry asbestos, so a licensed strip-out leads where demolition is involved.
