Baulkham Hills Home Builds — Made to Your Brief
A custom home in Baulkham Hills is a substantial family build on the kind of block the Hills is known for. This established mid-Hills suburb runs 1970s to 1990s brick homes on 600 to 900m2 R2 lots, and at a $1.6M to $2.4M median a designed replacement is a strong long-term play with schools and shopping close by. The generous blocks give the design real scope.
Those blocks open single or double-storey layouts with proper indoor-outdoor living, and the Wianamatta Shale ground gives footings stable, predictable bearing, so a slab off geotech is routine. Some lots along Old Northern Road carry R3, so a well-placed block is worth a quick density check, though on the standard R2 streets a single family home is the clean answer. There are no broad heritage overlays to work around.
What I would check first on your Baulkham Hills block: the building envelope the generous lot allows, any R3 potential near Old Northern Road, and the slab off geotech. Those set the design.
We build these fixed-price, licence HBL 487805C. Bring us your block and brief and we will draw it.
Buildana's design-and-construct service covers everything — from initial design brief and land assessment through to council approval and fixed-price construction. One builder, one contract, one point of contact.

Stable ground, quick zoning check

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. We come to your Baulkham Hills 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 Baulkham Hills 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 Baulkham Hills 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). Baulkham Hills 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.
⏱Quality Promise
We build custom homes in Baulkham Hills the way they should be built — one contractor, fixed price, accountability at every stage.
