Building Granny Flats in Plumpton
A granny flat builder in Plumpton works with affordable Blacktown stock — the 1980s to 1990s 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 the 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.
The Plumpton Marketplace shopping centre and access to main roads keep a rear dwelling lettable, and the affordable land base lifts the return. The generous blocks leave room for separate access and private open space.

Affordable, generous blocks
Plumpton'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 the shopping centre and main-road access keeping it lettable.
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.
