A granny flat builder in Emerton works with affordable stock near Mount Druitt — the 1960s to 1980s homes sit on standard 550 to 700m² blocks that clear the 450m² Housing SEPP threshold comfortably for a 60m² secondary dwelling. With prices among the lowest in the Blacktown LGA, this is a yield play as much as anything.
The ground is moderately to highly reactive, so the slab is a stiffened raft engineered off a real geotech. The 1960s to 1980s stock frequently carries fibro, so a licensed asbestos strip-out leads where any demolition is involved — I budget it upfront rather than have it surprise you.
Mount Druitt is about a kilometre and a half out, and the low land base is the real driver: a well-built rear dwelling returns strongly against a cheap block. The generous lots leave room for separate access.

Low land base, strong yield
Emerton's low prices make the yield case strong — the build cost is similar anywhere, but a well-built rear dwelling returns strongly against a cheap block.
The 550 to 700m² lots clear the 450m² Housing SEPP threshold comfortably, so a 60m² secondary dwelling is achievable on most via the CDC path.
Reactive clay, older stock
The moderately to highly reactive ground means the slab is a stiffened raft engineered off a real geotech.
The 1960s to 1980s stock frequently carries fibro, so a licensed asbestos strip-out leads where demolition is involved — budgeted upfront.
