A knockdown rebuild in Merrylands West suits the 1960s to 1980s stock on standard 450 to 650m² R2 and R3 blocks, in a quiet residential setting close to Merrylands station and shops. The aging stock makes a rebuild a sensible reset.
The ground is Class M shale, which takes a standard engineered slab off a geotech. The older homes can carry asbestos, so a licensed strip-out and clearance certificate lead the demolition where needed.
On the R3 blocks over the 600m² minimum, a duplex can be the stronger play, so I run both feasibilities where the block allows.

Quiet, close to the action
Merrylands West gives you a quiet residential setting with Merrylands station and shops close by. On standard 450 to 650m² blocks, the 1960s to 1980s stock is aging into rebuild territory, so a knockdown resets a dated home into a modern one.
It is a practical pocket for families who want convenience without the noise of the town centre.
Ground, asbestos and the duplex question
The Class M shale takes a standard engineered slab off a geotech. The older homes can carry asbestos, so a licensed strip-out and clearance certificate lead the demolition where needed.
On the R3 blocks over 600m², I cost the duplex alongside the single rebuild so you can see both returns.
