A knockdown rebuild in Cammeray costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, North Sydney Council approvals, and construction under one fixed-price contract.
Cammeray Knockdown Rebuilds
A knockdown rebuild in Cammeray suits the Federation, inter-war and post-war stock on tight 300 to 550m² blocks, on the ridge between Long Bay and Tunks Park with a strong village heart along Miller Street. It is a lower North Shore suburb where a well-designed rebuild on a compact block can deliver a genuinely smart home.
The tight blocks mean design matters — a rebuild here is about clever use of a compact footprint rather than a sprawling home. Heritage Conservation Areas cover several streets, so heritage is the first thing to check, and on the R3 land a dual-occupancy can be worth costing where a block clears the 500m² minimum.
The ground is Class M on the sandstone ridges, grading Class H to E on the harbour fall, so the slab is designed off a real geotech. The older stock can carry asbestos and lead paint, so a licensed strip-out leads the demolition.
We rebuild fixed-price, licence HBL 487805C. Get our feasibility — rebuild or dual-occupancy — before you commit.
Buildana manages the complete knockdown rebuild process in Cammeray — 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.

Tight blocks, clever design
Cammeray sits on the ridge between Long Bay and Tunks Park, with a strong village heart along Miller Street, on tight 300 to 550m² blocks. A rebuild here is about clever use of a compact footprint rather than a sprawling home, and good design makes the difference on a block this size.
The Federation, inter-war and post-war stock is largely into rebuild territory.
Heritage, yield and harbour-fall soil
Heritage Conservation Areas cover several streets, so a heritage block goes down the DA path with a sympathetic design. On the R3 land, a dual-occupancy can be worth costing where a block clears the 500m² minimum, so I run both where relevant.
The ground is Class M on the sandstone ridges, grading Class H to E on the harbour fall, so the slab is designed off a real geotech. The older stock can carry asbestos and lead paint, so a licensed strip-out leads the demolition.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. 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.
⏱The Cammeray construction phase. Fixed price, programmed, supervised. Demolition runs 5–10 working days for a standard Cammeray 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.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Walk through your finished home on your original Cammeray block. OC issued, all services live, 6-year structural warranty, appliance manuals, and maintenance schedule. Move in.
⏱Quality Promise
Cammeray knockdown rebuild done cleanly: licensed demolition, compliant slab, new home built to NCC 2025. Fixed-price contract.
