Knockdown Rebuild Palm Beach — One Contract, Demo to Keys
Everything under one agreement in Palm Beach 2108: demolition, asbestos removal, site prep, design, approvals, engineering, new home construction, landscaping and Occupation Certificate.
Quick Answer
A knockdown rebuild in Palm Beach costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Northern Beaches Council approvals, and construction under one fixed-price contract.
New Home on Your Palm Beach Block
A knockdown rebuild in Palm Beach is a rare and considered thing, because this is Australia's most exclusive beach suburb with genuinely significant architecture. The stock includes Sydney School modernist homes by Walter Burley Griffin and others, heritage beach houses and pole houses, and Heritage Conservation Areas cover the village, so demolishing a significant home is often restricted and always a serious decision. On many blocks, a sensitive restoration beats a knockdown.
Where a rebuild is genuinely warranted on a non-heritage block, the constraints are as demanding as anywhere: BAL ratings from 19 to Flame Zone, very deep rock excavation of $80K to $200K-plus, a Coastal Hazard zone on the beachfront, and a Foreshore Building Line on Pittwater frontage. Where the old home carries asbestos, a licensed strip-out and clearance certificate lead the demolition.
What I check first on your Palm Beach knockdown rebuild: whether the home is architecturally significant or heritage-listed, the BAL, the very deep rock, and the coastal and foreshore overlays. Those decide the play and the price.

Significant architecture, a serious decision
Palm Beach is Australia's most exclusive beach suburb, and its stock includes genuinely significant Sydney School modernist homes and heritage beach houses, with Heritage Conservation Areas over the village. Demolishing one of those is often restricted and always a serious decision, and on many blocks a sensitive restoration that respects the architecture beats a knockdown. So the first thing I do is assess the significance of your home honestly.
Where a rebuild is genuinely warranted on a non-heritage block, the setting rewards a home of real quality, designed to the ocean and Pittwater outlook. But that is a considered call, not a default.
The most demanding constraints in Sydney
A Palm Beach rebuild carries as demanding a set of constraints as anywhere in Sydney: BAL ratings from 19 to Flame Zone with mandatory RFS detailing, very deep rock excavation of $80K to $200K-plus, a Coastal Hazard zone on the beachfront, and a Foreshore Building Line on Pittwater frontage. Where the old home carries asbestos, a licensed strip-out and clearance certificate lead the demolition. I price all of it from real assessments rather than a guess.

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 Hawkesbury Sandstone 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 Palm Beach 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 Hawkesbury Sandstone soil) to keys — fixed-price, milestone-based progress payments. Your project manager provides weekly updates.
⏱Walk through your finished home on your original Palm Beach block. OC issued, all services live, 6-year structural warranty, appliance manuals, and maintenance schedule. Move in.
