A knockdown rebuild in Carlton costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Georges River Council approvals, and construction under one fixed-price contract.
Demolish and Rebuild in Carlton
A knockdown rebuild in Carlton is a solid renewal play — Federation cottages, inter-war heritage and 1960s to 1980s brick on 350 to 550m² R2 blocks between Kogarah and Allawah, with its own station and strong renewal activity already underway.
The R3 zoning along the station precinct opens medium-density where a block qualifies, and against the 600m² duplex minimum, the larger blocks can support a dual-occupancy. I run those numbers where they apply.
The ground is the shale-sandstone interface with reactive clay pockets, so the slab is designed off a real geotech. The pre-war stock carries asbestos and lead paint, so a licensed strip-out leads the demolition.
We rebuild fixed-price, licence HBL 487805C. Get our feasibility before you commit.

Renewal already underway
Carlton's renewal activity is genuine — the rail-line position between Kogarah and Allawah and the aging Federation and brick stock are driving steady knockdown activity. On 350 to 550m² blocks, a rebuild resets a dated home into a modern one in a well-connected pocket.
On the R3 station precinct, medium-density can be worth costing, and the larger blocks can support a duplex against the 600m² minimum.
Interface ground and old stock
The shale-sandstone interface with reactive clay pockets means the slab is designed off a real geotech — clay in some spots, rock in others.
The pre-war stock carries asbestos and lead paint, so a licensed strip-out leads the demolition.

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 Carlton homes from the 1920s–1960s heritage Federation/Californian Bungalow + 1960s–1990s brick veneer + 2010s+ R3/R4 redevelopment around Hurstville/Kogarah/Beverly Hills CBDs — 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 Carlton block you'd get on a greenfield build. The only difference is you still live in the street you chose.
⏱Quality Promise
Our Carlton knockdown rebuilds sequence demolition, slab, frame, lockup, handover. Fixed price locked before demolition starts.
