A knockdown rebuild in South Granville suits the post-war stock on standard 450 to 650m² R2 and R3 blocks, in a quiet residential pocket with established infrastructure and good access to Parramatta Road. The 1950s to 1970s homes are aging 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.

Quiet pocket, good access
South Granville is a quiet residential suburb with established infrastructure and handy access to Parramatta Road. On standard 450 to 650m² blocks, the post-war stock is aging into rebuild territory, so a knockdown resets a dated home into a modern one.
It keeps you close to Granville and the broader Parramatta area while staying in a settled street.
Asbestos and the duplex question
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 cost the duplex alongside the single rebuild so you can see both returns.
