Knockdown Rebuild Allawah — From $450K All-In
Fixed-price knockdown rebuild in Allawah 2218. Demolition, new home, all Georges River Council approvals under one contract. No surprises, no variation trail.
New Home on Your Allawah Block
A knockdown rebuild in Allawah is a compact station-suburb play — Federation cottages, inter-war heritage and 1960s-90s brick on 350 to 550m² R2 blocks between Hurstville and Carlton, with renewal strong and its own station.
The blocks run tighter than the neighbouring suburbs, so the survey matters — on the larger lots a rebuild works cleanly, while the R3 along the station precinct can make medium-density the bigger play on qualifying blocks.
The shale-sandstone interface means the slab is designed off a real geotech, and 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.
Buildana manages the complete knockdown rebuild process in Allawah — from site assessment and architectural design through to DA or CDC approval, demolition management, and fixed-price construction to handover. One builder, one contract, one new home.

Compact blocks, survey first
Allawah's 350 to 550m² blocks run tighter than the neighbouring suburbs, so the survey does more of the deciding — on the larger lots a rebuild works cleanly, designed to the envelope. The station and the renewal momentum keep demand genuine.
On the R3 station precinct, medium-density can be the bigger play, which I check first.
Interface ground and old stock
The shale-sandstone interface means 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.
Both are in the feasibility and the fixed price.
