A knockdown rebuild in Wentworthville is a strong play on the post-war stock, with the suburb's own train station and a central location that drives real rebuild demand. The 1950s to 1970s homes on standard 450 to 650m² R2 and R3 blocks are well into rebuild territory.
The ground is Class M shale, which takes a standard engineered slab off a geotech. The post-war homes usually carry asbestos, so a licensed strip-out and clearance certificate lead the demolition.
On the R3 blocks over the 600m² minimum, a duplex can be the stronger return, so I run both feasibilities where the block allows. The rail access supports either play.

Central, well-connected, in demand
Wentworthville's own train station and central location drive genuine rebuild demand. On standard 450 to 650m² blocks, the 1950s to 1970s post-war stock is well into rebuild territory, so a knockdown resets a dated home into a modern one with strong connectivity.
It is a suburb where a well-built rebuild has a solid market behind it.
Asbestos first, then the duplex maths
The Class M shale takes a standard engineered slab off a geotech. The post-war stock usually carries asbestos, so a licensed strip-out and clearance certificate lead the demolition.
On the R3 blocks over 600m², I run the duplex numbers alongside the single rebuild so you can choose on real figures.
