A granny flat builder in Fairfield is on home ground — this is where Buildana is based, so I know the blocks and the Fairfield City controls first-hand. The mixed-era stock sits on 450 to 700m² R2 and R3 lots, so most blocks clear the 450m² threshold for a 60m² secondary dwelling under the Housing SEPP, and the CBD, station and schools give a granny flat a deep tenant pool of commuters, students and extended family.
The ground runs moderately to highly reactive clay, so the slab is engineered as a stiffened raft off a real geotech to hold against clay movement. The 1950s to 1980s stock often carries fibro, so a licensed asbestos strip-out comes first where demolition is involved. Separate access off the rear keeps the dwelling lettable.
What I check first on your Fairfield block: whether the survey clears 450m² for the CDC path, the rear-yard access and setbacks, and the slab off geotech. Those decide the pathway and the yield.

Home ground, deep tenant pool
Fairfield is Buildana's base, so the Fairfield City controls and the local blocks are known ground. Most 450 to 700m² lots clear the 450m² Housing SEPP threshold, so a 60m² secondary dwelling is achievable on the majority of blocks.
The CBD, the station and the schools give a granny flat a wide tenant pool — commuters, students and extended family — which keeps the yield strong.
Reactive clay and older fibro
The moderately to highly reactive clay means the slab is engineered as a stiffened raft off geotech, stable against clay movement.
The 1950s to 1980s stock often carries fibro, so a licensed asbestos strip-out leads where demolition is involved.
