A custom home in Cattai costs $450,000–$1,200,000+ depending on size and specification. Single storey from $450K, double storey from $650K. Buildana manages design, The Hills Shire Council approvals and fixed-price construction.
Building Custom Homes in Cattai
A custom home in Cattai is a rural acreage build where the whole site, not just the house, is the project. These are 2 to 10 hectare-plus RU2 holdings with Hawkesbury River foreshore on the northern edge, and at a $2.5M to $6M-plus acreage market a designed homestead is a considered, long-term build. The land is the reason people are here, and the home has to sit within it properly.
This is significant bushfire country, so a BAL rating and an RFS assessment drive the construction spec, and Hawkesbury Sandstone means rock is assessed and priced honestly. Riparian setbacks apply along Cattai Creek, on-site effluent means an AWTS wastewater system, and siting has to weigh access, bushfire, flooding near the river and outlook all at once. Cattai National Park adjacency frames a genuinely rural setting.
What I would check first on your Cattai property: the BAL rating and bushfire spec, the riparian and flood setbacks near the creek and river, and the wastewater system. Those set the home.
We build these fixed-price, licence HBL 487805C. Show us the property and we will design the home and its siting together.
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.

The whole site is the project

At a $2.5M to $6M-plus acreage market a designed homestead has to sit within the land, which is the reason people are here.
Bushfire, water and siting
This is significant bushfire country, so a BAL rating and RFS assessment drive the spec, on Hawkesbury Sandstone with rock priced honestly.
Riparian setbacks apply along Cattai Creek, on-site effluent means an AWTS system, and siting weighs access, bushfire and flooding together.

How It Works
From First Call to Final Key
We start at the kerb. Before a single sketch, we stand on your Cattai block and work out what the land wants — sun path, slope, views, neighbours, the R2 Low envelope we've got to design inside. That walk determines almost every decision that follows.
⏱Design happens in layers. First the plan — where the kitchen is, how the bedrooms stack, what the morning routine looks like. Then the envelope — roof pitch, eave depth, window sizes matched to the Cattai climate. Then the finishes. Nothing gets drawn without a reason you can point to.
⏱Documentation is the unglamorous part, but it's where most projects go wrong. Engineering for Class M soil, BASIX 2025, The Hills Shire Council drawings, hydraulics, stormwater. We stage it so the certifier approves the first time — not the fourth.
⏱Then we build. Programme in hand, trades booked, material orders placed weeks before they're needed so nothing waits on delivery. Weekly update, monthly milestone walk, defects fixed as we go rather than collected at the end.
⏱Quality Promise
Cattai custom home construction done properly: design tailored to your block, compliance handled, pricing locked in before we start.
