A custom home in Sadleir costs $450,000–$1,200,000+ depending on size and specification. Single storey from $450K, double storey from $650K. Buildana manages design, Liverpool City Council approvals and fixed-price construction.
Custom Homes Designed for Sadleir
A custom home in Sadleir is an affordable family build in a small Liverpool suburb. The streets run established 1960s to 1970s housing on standard blocks, and at a $700K to $850K median a designed replacement changes the value proposition for families and investors. It is an attractive entry to the Liverpool LGA with genuine renewal opportunity close to the CBD.
This is Liverpool LGA on reactive clay, so footings are engineered to suit the ground off geotech and the slab is detailed for the movement. The standard blocks suit efficient single or double-storey family designs, and where older homes carry fibro a licensed asbestos strip-out comes first. The local shops and the Catholic Club anchor the suburb.
What I would check first on your Sadleir 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 Sadleir 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 Sadleir 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 H soil, BASIX 2025, Liverpool 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.
⏱Quality Promise
We build custom homes in Sadleir the way they should be built — one contractor, fixed price, accountability at every stage.
