The detail

What a good home building quote includes

A good quote spells out how the job is priced and what's covered — labour, materials, prep and clean-up — so you're comparing like for like. Check what each builder's quote covers before you choose.

Worth knowing: getting two or three quotes is the simplest way to land a fair price — and it costs you nothing.

  • Itemised scope. Every stage listed, site prep to finishing, not a lump sum.

  • Material specs. Exact brand, grade and quantity, not 'good quality'.

  • Exclusions. Driveways, landscaping, fencing and site costs are classic traps.

  • Prime cost and provisional sums. Allowances for choices and site work not priced yet.

  • Licence and insurance. ABN, licence, public liability and home warranty cover.

  • Permits. Who gets permits, soil tests and compliance certificates.
