A knockdown rebuild in Lane Cove West costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Lane Cove Council approvals, and construction under one fixed-price contract.
Knockdown Rebuild Builder in Lane Cove West
A knockdown rebuild in Lane Cove West depends heavily on your street, because this river-fall suburb has Heritage Conservation Areas over several streets. On a heritage street, demolition is restricted and a sensitive restoration is the path. On the non-heritage blocks, a rebuild designed to the river and bushland outlook is a play, but the deep rock and the fall make it a considered, higher-cost job.
The sandstone-dominant ground means the substantial fall to the river adds engineering and rock excavation on any rebuild, and bush-edge lots carry a BAL rating the new home must meet. Where the older home carries asbestos in later additions, a licensed strip-out and clearance certificate lead the demolition.
What I check first on your Lane Cove West knockdown rebuild: whether you sit inside a Heritage Conservation Area or on a bushfire-rated bush-edge lot, the river fall and rock, and asbestos in the demolition. Those decide the play.

Heritage, river fall and bushfire
Lane Cove West runs along the Lane Cove River with Heritage Conservation Areas over several streets, so on a contributing home demolition is restricted and a sensitive restoration is the path. On the non-heritage blocks, a rebuild designed to the river and Lane Cove National Park outlook is a genuine play, though the fall and the bushfire on bush-edge lots shape it. So the first thing I do is check the heritage and bushfire layers.
Where a rebuild does stack up, the river-fall setting gives a new home a genuinely desirable outlook worth designing to.
Deep rock and the fall
The sandstone-dominant ground and the substantial fall to the river mean any rebuild carries real engineering and rock excavation, priced from a real geotech. Bush-edge lots also carry a BAL rating the new home must meet. Where the older home carries asbestos in later additions, a licensed strip-out and clearance certificate lead the demolition. I price the fall, rock, bushfire and clearance from real assessments.

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 Lane Cove West 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 Lane Cove West block. OC issued, all services live, 6-year structural warranty, appliance manuals, and maintenance schedule. Move in.
⏱Quality Promise
Buildana handles Lane Cove West KDR end-to-end — old house out, new house in, one contract, one contractor, one defined timeline.
