A granny flat builder in Oakhurst works with affordable 1980s to 1990s stock — the 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 more affordable in Blacktown LGA, the rental-yield case leads.
The ground is moderately to highly reactive, so the slab is a stiffened raft engineered off a real geotech. The stock is late enough that fibro is uncommon, which keeps the build clean where a structure needs removing from the build zone.
Mount Druitt is a couple of kilometres out with good local amenities, and the affordable land base lifts the return. The generous blocks leave room for separate access and private open space.

Affordable, generous blocks
Oakhurst's 550 to 700m² lots clear the 450m² Housing SEPP threshold comfortably, so a 60m² secondary dwelling is achievable on most blocks via the CDC path.
The affordable land base lifts the return on a well-built rental, with Mount Druitt's amenities a couple of kilometres out.
Reactive clay, clean stock
The moderately to highly reactive ground means the slab is a stiffened raft engineered off a real geotech.
The 1980s to 1990s stock rarely carries fibro, which keeps the build clean where a structure needs removing.
