About
A registered building surveyor you can actually get on the phone.
Cornerstone is a building surveying practice issuing building permits and carrying out inspections across Melbourne and all of Victoria.
You deal directly with the registered building surveyor named on your permit, and that surveyor stays accountable for it from the first assessment through to sign-off. One practice, one fixed fee, one office to ring. Builders tell us that continuity is the reason they keep sending work; owner-builders tell us it's the reason the process made sense. Suppliers, installers and builders referring a customer: here is how that works.
We take on every class of building work across residential, commercial and industrial: new homes, extensions, dual occupancies and townhouses, sheds and garages, retaining walls, verandahs and decks, demolition, warehouses, offices and shop fit-outs, and change of use. Every job is assessed against the Building Act 1993, the Building Regulations 2018 and the National Construction Code, and every fee is fixed before we start.
We also assess unapproved building works and respond to building notices, calmly and with a realistic view of what can be approved.

How we work
Six things that stay the same on every job.
No volume statistics, no slogans. This is what you can hold us to.
- 01
Accountable from permit to sign-off
Your permit is issued under a registered building surveyor who stays accountable for the job from assessment to sign-off. Questions get answered by the person responsible for the answer — one practice, one office to ring.
- 02
Fixed fees, quoted before we start
One number for the assessment, the permit and the mandatory inspections. Levies and any council consent fees are itemised separately, up front.
- 03
Missing information asked for once
We read the whole file before we come back to you, so the request for information is one list — not a drip-feed that stalls the job.
- 04
Builders get volume handled quietly
Repeat work from builders and drafting firms runs on a predictable fee schedule and a direct line. No re-explaining the job each time.
- 05
Owner-builders get straight answers
Whether it's a shed, a retaining wall or a knock-down rebuild, we tell you what's needed, what's exempt and what's going to be a problem before you commit.
- 06
Statewide, with real logistics
Permits and inspections across Melbourne and all of Victoria. Regional jobs are scheduled in runs so inspections aren't held up by distance.
