A knockdown rebuild in Macarthur costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Campbelltown City Council approvals, and construction under one fixed-price contract.
New Home on Your Macarthur Block
A knockdown rebuild in Macarthur is worth weighing against the precinct options, because this is the rail interchange and WSU campus precinct — Macarthur Square, the station, and R3/R4 redevelopment with strong university and hospital staff demand.
On the R2 streets, a rebuild of the 1980s-2010s stock works, and the 500m² duplex minimum puts a dual-occupancy in play on the larger blocks — with the WSU-and-hospital tenant base making the yield story real. Near the station, precinct value can dominate.
The Wianamatta Shale takes a slab designed off a real geotech, and the older stock can carry asbestos, so a licensed strip-out leads the demolition where needed.

A precinct with a real tenant base
Macarthur's interchange, Macarthur Square and the WSU campus generate genuine tenant demand, and the 500m² duplex minimum puts a dual-occupancy in play on the larger blocks. On the R2 streets, a rebuild works; near the station, R3/R4 precinct value can dominate — I check first.
The yield story here is real, backed by university and hospital staff.
Shale and era demolition
The Wianamatta Shale takes a slab designed off a real geotech. The older stock can carry asbestos, so a licensed strip-out leads the demolition where needed.
Both are in the feasibility and the fixed price.

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 Macarthur homes from the 1980s–2010s + premium contemporary — 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 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 Macarthur block you'd get on a greenfield build. The only difference is you still live in the street you chose.
