A custom home in Bonnyrigg Heights is a family rebuild on a well-sized block in a quiet residential pocket. The suburb runs 1970s to 1990s homes on generous lots, and at a $950K to $1.2M median a designed replacement suits owners upgrading in place rather than moving out. The settled character and the space are the draw for families here.
This is Fairfield LGA on reactive clay, so footings are engineered to suit the ground off geotech and the slab is detailed for the movement. The generous blocks open single or double-storey family designs with a proper backyard, and there are no broad heritage overlays to work around, which keeps the approval path predictable. Where older homes carry fibro a licensed asbestos strip-out comes first.
What I would check first on your Bonnyrigg Heights block: the reactive-clay footing design, the building envelope, and any asbestos in older stock. Those set the home.
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.

How It Works
From First Call to Final Key
We start at the kerb. Before a single sketch, we stand on your Bonnyrigg Heights block and work out what the land wants — sun path, slope, views, neighbours, the R2 Low Density 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 Bonnyrigg Heights 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–H soil, BASIX 2025, Fairfield City 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.
