A knockdown rebuild in Maraylya costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, The Hills Shire Council approvals, and construction under one fixed-price contract.
New Home on Your Maraylya Block
Calling it a knockdown rebuild undersells what happens in Maraylya, on 2 to 10ha acreage holdings, replacing the old farmhouse is a rural build with rural rules. RU2 zoning, significant bushfire exposure, riparian setbacks along the Cattai Creek tributaries, and Hawkesbury Sandstone under a lot of it. None of that appears in a standard KDR quote, and a builder pricing your project like a suburban block will get it wrong in both directions.
The land justifies doing it properly, $2.5M to $6M-plus medians reflect what these equestrian and lifestyle holdings are worth with the right home on them. Expect an RFS assessment driving BAL construction levels, on-site effluent design where sewer does not reach, and siting decisions that balance the setbacks against the views. No rail out here, the trade-off is space nobody in suburban Sydney gets.
What I would check first on a Maraylya holding: the RU2 rules and BAL rating, the riparian setbacks and effluent design, and the sandstone. Those decide the pathway.

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 Mixed rural-era home. Clear feasibility report before you commit.
⏱Approval pathway gets locked at design stage based on FSR, height, setbacks, and any overlays. Most Maraylya 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.
