A knockdown rebuild in Henley costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Hunters Hill Council approvals, and construction under one fixed-price contract.
Henley Knockdown Rebuilds
A knockdown rebuild in Henley depends heavily on your street, because this small Parramatta River foreshore suburb of Hunters Hill has Heritage Conservation Areas over most streets. On a heritage-listed street, demolition is restricted and a sensitive restoration is the path. On the rare non-heritage block, a rebuild on the river fall is a play, but the deep rock makes it a considered, higher-cost job.
The sandstone-dominant ground means deep rock excavation on the new slab and footings, and the substantial fall to the river drives real engineering. Where the older home carries asbestos in later additions, a licensed strip-out and clearance certificate lead the demolition. The heritage layer is the first check.
What I check first on your Henley knockdown rebuild: whether you sit inside a Heritage Conservation Area where demolition is restricted, the depth to rock and the river fall, and asbestos in the demolition. Those decide the play.

Heritage covers most of Henley
Henley is a small Hunters Hill foreshore suburb with Heritage Conservation Areas over most streets, so on a contributing Federation or inter-war home demolition is restricted and a sensitive restoration is the path. A knockdown rebuild is off the table on the bulk of Henley blocks, and I would rather establish that from the heritage layer than have a rebuild refused.
On the rare non-heritage block, a rebuild designed to the Parramatta River outlook is a genuine play, but the deep rock makes it a considered, higher-cost job. So I check the heritage layer first.
Deep rock and river fall
The sandstone-dominant Henley ground means deep rock excavation on the new slab and footings is typical, priced from a real geotech rather than assumed, and the substantial fall to the river drives real structural design on any rebuild. Where the older home carries asbestos in later additions, a licensed strip-out and clearance certificate lead the demolition. I price the rock, the fall and the clearance from real assessments.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. On-site assessment covers block measurements, soil conditions (Class Hawkesbury Sandstone bedrock), tree preservation checks, service locations, and asbestos identification on your 1880s–1940s Federation/Victorian/inter-war heritage predominant (Heritage Conservation Areas cover virtually entire LGA) + premium contemporary infill-era home. Clear feasibility report before you commit. Approval pathway gets locked at design stage based on FSR, height, setbacks, and any overlays. Most Henley KDRs go CDC for speed; we use DA when the design wants to push past complying development limits. Either way, all documentation prepared and lodged in-house.
⏱The Henley construction phase. Fixed price, programmed, supervised. Existing home demolished by licensed contractors. Asbestos removed and disposed of to EPA standards. Services disconnected, site cleared and prepped for construction. Buildana manages all permits and logistics. Construction starts the week demolition finishes — no idle site, no momentum lost. Slab pour usually within the first month, frame stand soon after. From frame stand to handover runs 6–9 months for a typical Henley family home.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Final inspection, Occupation Certificate, 6-year structural warranty, keys, and maintenance guide. Services reconnected. Your new home near Henley shops + Henley wharf + Parramatta River foreshore.
