Licensed Knockdown Rebuild Builder Northwood
NSW licensed KDR specialist in Northwood 2066. Asbestos-accredited demolition, Class M engineered slab, BASIX 2025, 6-year structural warranty on the new home.
Quick Answer
A knockdown rebuild in Northwood 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.
Northwood Knockdown Rebuilds
I will be straight with you: Northwood is rarely a knockdown rebuild suburb. This small harbour-fall enclave on Woodford Bay is dominated by Federation mansions and inter-war heritage, and Heritage Conservation Areas cover virtually all streets, so demolishing a significant period home is heavily restricted. On most Northwood blocks a knockdown rebuild has little path.
What the enclave rewards is a high-end heritage restoration that restores the significant period home and captures the protected harbour outlook, with engineered foundations on the substantial fall. In a $4M-plus tightly-held market, that is where the value is, not in a knockdown council will refuse.
What I check first on your Northwood property: the near-total Heritage Conservation Area controls, the harbour fall, and whether demolition is even permissible. Those confirm the realistic path is a restoration.

Why a knockdown rarely works here
Northwood is a small, tightly-held harbour enclave of Federation mansions on Woodford Bay, and with Heritage Conservation Areas over virtually all streets, demolishing a significant period home is heavily restricted. A knockdown rebuild has little path on most blocks, and I would rather establish that from the heritage layer than draw plans that get refused.
If a builder is promising you a Northwood knockdown without checking the heritage controls, be sceptical, because they cover essentially the whole enclave.
Restoration and the harbour fall
What Northwood rewards is a high-end heritage restoration that restores the significant period home and captures the protected Woodford Bay outlook. On the substantial fall to the water, engineered foundations are standard, and the sandstone gets assessed from a real geotech. I would rather restore you a landmark harbourside home than pursue a knockdown that cannot happen.

How It Works
From First Call to Final Key
On-site assessment covers block measurements, soil conditions (Class M), tree preservation checks, service locations, and asbestos identification on your 1880s–1940s heritage-era home. Clear feasibility report before you commit.
⏱Approval pathway gets locked at design stage based on FSR, height, setbacks, and any overlays. Most Northwood KDRs go CDC for speed; we use DA when the design wants to push past complying development limits.
⏱Existing home demolished by licensed contractors. Asbestos removed and disposed of to EPA standards.
⏱Construction starts the week demolition finishes — no idle site, no momentum lost. Slab pour usually within the first month, frame stand soon after.
⏱Final inspection, Occupation Certificate, 6-year structural warranty, keys, and maintenance guide. Services reconnected.
⏱Quality Promise
Northwood knockdown rebuild done cleanly: licensed demolition, compliant slab, new home built to NCC 2025. Fixed-price contract.
