A note from Oliver
“What you actually want to know is whether the bloke who quoted you is the same one answering the phone in month seven. On our jobs that’s me, both times.”

Before you build
Good questions.
Straight answers.
The budget, your block and what happens next. Start here, then ask us about your own project.
Ask Oliver directly0476 300 300How much does it cost to build a home in Sydney?
A useful price starts with a defined scope. The size of the home, site conditions, design and selections all affect the cost. Send us your address and what you want to build; we can discuss the next steps towards a site-specific quote.
Talk through your projectWhat areas does Buildana build in?
We’re based in Fairfield and build across greater Sydney, with a strong focus on Western Sydney. That includes Liverpool, Cumberland, Canterbury-Bankstown, Blacktown, Penrith, Campbelltown and Camden. Tell us where your block is and we’ll discuss your project.
Explore our building areasHow long does it take to build a house?
There are two different timeframes: getting the project ready to build, and the construction itself. Design, approvals, site conditions and the scale of the work all matter. Ask us for a project-specific program, including the assumptions behind the dates.
How we workWhat is a CDC and how is it different from a DA?
A complying development certificate (CDC) combines planning and construction approval for eligible development that meets the applicable standards. A council or accredited certifier can assess it. A development application (DA) follows a planning assessment process, usually through council. The right pathway depends on the site and proposed work; not every block qualifies for a CDC.
Read the NSW planning guidanceDoes Buildana offer fixed-price contracts?
Yes, for an agreed scope of work. The contract and inclusions should make clear what is covered and what is excluded. If you change the design or selections, discuss the cost and any timing impact before agreeing to the change.
Ask about your scope and budgetCan I build a granny flat on my property?
That needs a site check, not just a lot-size calculation. Zoning, access, setbacks, easements and other site constraints can affect what is possible and which approval pathway applies. Send your address so we can discuss the checks needed for your block.
