A knockdown rebuild in Strathfield South costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Burwood Council approvals, and construction under one fixed-price contract.
Strathfield South Knockdown Rebuilds
A knockdown rebuild in Strathfield South is a practical inner-west play — Federation cottages, inter-war heritage and post-war brick on 300 to 550m² blocks south of Strathfield, with the Cooks River fringe the main site check.
On the southern fringe, the Cooks River alluvial brings flood planning controls that can set floor levels — checked upfront. On the larger detached lots, a rebuild works cleanly, and the 550m² duplex minimum comes into play on the biggest blocks.
The Wianamatta Shale with reactive clay pockets 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, with the flood fringe checked, before you commit.
Buildana manages the complete knockdown rebuild process in Strathfield South — 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.

Practical, with a river fringe
Strathfield South's 300 to 550m² blocks of aging Federation-to-post-war stock suit a practical rebuild, with Strathfield's amenity close. On the southern fringe, the Cooks River alluvial brings flood planning controls that can set floor levels — checked upfront.
On the larger detached lots, a rebuild works cleanly.
Reactive pockets and old stock
The Wianamatta Shale with reactive clay pockets means the slab is designed off a real geotech, with the alluvial fringe needing a designed footing. 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.

How It Works
From First Call to Final Key
Site visit covers everything that affects the build cost: vehicle access for trucks and crane, services (sewer depth, water connection, electrical service rating), soil exposure for borehole, neighbouring construction, and any obvious heritage or tree constraints. Real numbers, not estimates.
⏱Architectural design for your replacement home, structural engineering for Class M soil, BASIX certification, and all approval documentation. Lodged as CDC (10–15 days) or DA (40–90 days) depending on design.
⏱Demolition runs 5–10 working days for a standard Strathfield South cottage — longer if asbestos volume is significant or the structure includes a brick chimney or solid-block walls. Asbestos work happens first under a controlled removal program before mechanical demo starts.
⏱New home built from engineered slab (Class M soil) to keys — fixed-price, milestone-based progress payments. Your project manager provides weekly updates.
⏱Walk through your finished home on your original Strathfield South block. OC issued, all services live, 6-year structural warranty, appliance manuals, and maintenance schedule.
