A knockdown rebuild in Smithfield works on the 1960s to 1980s residential stock, on well-sized 450 to 700m² R2 blocks in the streets set back from the Smithfield–Wetherill Park industrial area. A rebuild gives you a modern home with a good building envelope in a practical, well-located pocket.
The ground runs from shale to reactive clay across the suburb, so the slab is designed off a real geotech for what your block has. Where it is reactive, that means a stiffened raft rather than an assumed footing.
The older homes can carry asbestos, so a licensed strip-out and clearance certificate lead the demolition where needed. Smithfield is R2, so this is a single-home rebuild suburb.

Practical, well-located blocks
Smithfield's residential streets sit back from the industrial precinct, on 450 to 700m² R2 blocks that give a rebuild a solid building envelope. It is a practical suburb with good access to the western Sydney network, so a modern home here works well for families and workers alike.
The 1960s to 1980s stock is aging into rebuild territory, so a knockdown resets a dated home rather than patching it.
Test the ground, then demolish
The ground under Smithfield runs from shale into reactive clay, so the slab is designed off a real geotech for your specific block. On the reactive-clay lots that means a stiffened raft, which is where under-built slabs come undone.
The older homes can carry asbestos, so a licensed strip-out and clearance certificate lead the demolition where the inspection calls for it. I price both into the feasibility.

How It Works
From First Call to Final Key
KDR starts with an honest look at the existing house. Sometimes it's worth keeping. Most Smithfield homes from the 1960s–1980s — especially fibro and brick-veneer — are beyond the point where renovation makes sense. We tell you straight.
⏱Demolition is pre-approved to run parallel with rebuild design. Asbestos cleared, services abolished, site stripped in a single mobilisation. Geotech reconfirms Class M–H soil with the old house gone.
⏱New house goes up on the same footprint or a better one, whichever serves the block. Modern NCC envelope, better orientation, fit-for-purpose room sizes. The suburb stays the same; the house finally fits it.
⏱Final handover: new OC, six-year structural warranty, all the documentation on your Smithfield block you'd get on a greenfield build. The only difference is you still live in the street you chose.
