A granny flat builder in Smithfield works with standard residential blocks close to the Fairfield employment area. The 1960s to 1980s stock sits on 450 to 700m² lots that mostly clear the 450m² threshold for a 60m² secondary dwelling under the Housing SEPP, and proximity to the Smithfield–Wetherill Park industrial area gives a granny flat a steady local-worker tenant pool.
The ground is moderately to highly reactive clay, so the slab is engineered off a real geotech to suit. The older 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 Smithfield block: whether the survey clears 450m² for the CDC path, the rear-yard access and setbacks, and the slab off geotech.

Standard blocks, worker tenants
Smithfield's 450 to 700m² blocks mostly clear the 450m² Housing SEPP threshold, so a 60m² secondary dwelling is achievable on most.
The adjacent industrial area gives a granny flat a steady local-worker tenant pool, which keeps the yield reliable.
Reactive clay and fibro
The moderately to highly reactive clay means the slab is engineered off a real geotech to suit.
The 1960s to 1980s stock often carries fibro, so a licensed asbestos strip-out leads where demolition is involved.
