Kenthurst Home Builds — Made to Your Brief
A custom home in Kenthurst is an acreage estate build, and that shapes the whole project. On 1 to 10ha RU2 holdings of Hawkesbury Sandstone, the home is designed as part of a whole-of-site plan that accounts for bushfire, on-site services and how the house sits in the landscape. Owners in the $3M to $8M-plus range are building the long-term family estate.
The compliance stacks up. Bushfire overlays are significant, so an RFS assessment and BAL-rated construction apply, on-site services including a certified AWTS are designed in where there is no sewer, and sandstone means excavation is priced by test dig. Siting the home for aspect, access and the equestrian or lifestyle use matters as much as the floor plan.
What I would check first on a Kenthurst holding: the BAL rating and RFS path, the on-site services design, and where the home should sit on the land. Those drive the project.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. We come to your Kenthurst site or you visit our office on The Horsley Drive in Fairfield. Either way, you leave the meeting with a clear cost band, an outline timeline, and a yes/no on whether your block supports the home you have in mind. The hard yards happen here, not at design lock-in. Our designer draws up plans matched to your Kenthurst block — north-facing living, compliant setbacks, garage placement, and outdoor flow. You get floor plans, elevations, and 3D renders to review before we lock in the design.
⏱The Kenthurst construction phase. Fixed price, programmed, supervised. Documentation is where bad builders cut corners and good builds stay on track. Buildana commissions the borehole, instructs the engineer, prepares BASIX, and aligns hydraulic, structural, and architectural drawings before lodgement. Certifiers reject sloppy packages — ours go in clean. CDC fast-track (10–15 business days) or DA through The Hills Shire Council (40–90 days). Kenthurst is zoned R2 Low. Construction Certificate obtained before works commence. Slab, frame, lock-up, fit-out, external works — all under fixed-price contract. Dedicated project manager on your build, weekly progress reports, and quality inspections at every critical hold point.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. OC, six-year structural warranty, two-year non-structural warranty, all manufacturer warranties on appliances and fixtures, BASIX certificate, certifier sign-offs, and maintenance schedule — all handed over in a single documentation pack. Keep it for your records and any future sale.
