Licensed Custom Home Builder Blacktown — Design & Construct
NSW licensed builder (Oliver Alameri) delivering fixed-price custom homes across Blacktown 2148. Engineered slab for Class M–H soil, BASIX 2025, 6-year structural warranty.
Blacktown Custom Home Construction
Compare Blacktown to almost any suburb closer to the harbour and the custom build case gets loud. Blocks run 550 to 750m², wider than most of inner Sydney, medians sit at $850K to $1.1M, and the suburb has its own station, Westpoint, and Blacktown Hospital within reach. You can buy a 1960s to 1980s original, knock it down, and build a genuinely new custom home for less than an apartment costs in half of Sydney.
One thing to respect. The soil grades M to H, so some blocks carry reactive clay that needs a properly engineered slab. It is a known quantity, not a dealbreaker, and we design for it from the soil test onward rather than discovering it mid-build.
What I would check first on a Blacktown block: the soil grade for slab design, the age of the existing house, and the budget. Those set the plan.
We build these to last, fixed-price, licence HBL 487805C. If you are a first-time builder or an upgrader wanting real space, get us to look at the block before you sign.
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.

Wide blocks, loud value
Blacktown's blocks run 550 to 750m², wider than most of inner Sydney, at a $850K to $1.1M median, with its own station, Westpoint and Blacktown Hospital within reach. You can buy a 1960s to 1980s original, knock it down and build genuinely new for less than an apartment costs in half of Sydney.
For a first-time builder or an upgrader wanting real space, that is a compelling case, and the wide blocks take a full family home with a yard.
Respect the clay
The one thing to respect is the soil. It grades M to H, so some blocks carry reactive clay that needs a properly engineered slab. It is a known quantity, not a dealbreaker.
We design for it from the soil test onward rather than discovering it mid-build. Send us the address and we will look at the block before you sign.

How It Works
From First Call to Final Key
We come to your Blacktown 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 Blacktown 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.
⏱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 Blacktown City Council (40–90 days). Blacktown is zoned R2 Low Density & R3 Medium Density. 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.
⏱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.
