Building a house in Australia sounds straightforward… until you actually start.

One wrong call can blow out your budget. Delay your build for months, or lock you into mistakes you can’t undo.

So before you sign anything, touch the site, or choose a builder, read this.

I’m going to walk you step-by-step through the entire building process in Australia. All the way through to handover, so you know exactly what’s coming and exactly how to avoid the costly traps first-timers fall into.

Hi, I’m Peter Kelly from Little Fish. If you’re new around here, we keep things simple, we help everyday Aussies build smarter, avoid the traps. And get clarity around their property journey.

And today, I’m going to take you through the actual stages of building a house in Australia. From start to finish, in plain English. No fluff, no jargon and no sugar-coating.

This guide follows the full process of building a house, from pre-build planning right through to construction, handover, and what happens after you move in.

Now, before we jump into the pre-build work, it’s important to understand how construction stages and payments actually work across Australia.

When it comes to build contracts, there are generally two ways they’re structured.

First is what is referred to as method A and is the more traditional one with five major stages of construction.

Construction Stages

Here in Victoria, where we’re based, those five stages are Base Stage, Frame Stage, Lock-Up Stage, Fixing Stage and Completion Stage. Other states might use slightly different names, but the flow is basically the same nationwide.

The second is Method B. Which breaks those same stages down into smaller substages. Which means the builder receives more regular payments throughout the build.

Builders often prefer this method, and to be honest, we’ve embraced it more and more over recent years. Because better cashflow for the builder usually means they can keep things moving faster out on site. Which is better for everyone.

For this video, we’re going to follow Method A because it’s the cleanest and simplest way to explain the entire building process from start to finish.

Everything before those stages is considered pre-build work, and that’s where we’ll start.

Pre-Build Phase 1: Your Vision & Budget

Before you even start thinking about the types of concrete slabs, frames, tiles, colours, any of that stuff, you’ve got to dial in two things first. And these two things will decide exactly how smooth or how painful the rest of your build is going to be.

The first one’s simple: what do you actually want to build? I’m talking bedrooms, layout, how flexible you need the home to be, what you’ll need in a few years’ time, and how energy-efficient you want it. Think about all your non-negotiables.

You need that picture in your head before you go any further.

And the second thing is just as important: how much do you realistically want to spend? Not your dream budget, your real budget. The actual number you’re comfortable with.

Because your total cost isn’t just the price of the house. There are all the extras that add up quickly, site costs, approvals, utility connections, landscaping, upgrades, and you’ve got to have a contingency buffer in there as well.

If you don’t get this bulletproof and locked in early, you will overspend before the build even starts.

This is also where understanding the real cost to build a house becomes critical, because that base construction figure sets the foundation for your entire budget and everything else stacks on top of it.

Pre-Build Phase 2: Choose Your Block & Due Diligence

The next step is choosing your block and doing your due diligence. This is the part most beginners skip, and it’s the part that bites the hardest.

A block can look perfect… and still turn into a nightmare once you dig a little deeper.

You’ve got to look at everything together. The slope of the land, the soil conditions, how the drainage works, whether it’s in a bushfire zone, if it’s prone to flooding, and whether there are any easements running through it.

On top of that, you need to know your setback restrictions and check if there are any heritage or neighbourhood character rules that limit what you can build.

And before you can design anything properly, you’ll need a surveyor to complete what’s called a re-establishment survey, along with a full feature and level survey of the block.

This tells you exactly where your boundaries are, where the services sit, the natural ground levels, and how the land actually falls, which is critical for drainage, setbacks, and placing the house correctly on the site.

Your builder, designer, or surveyor can help you with all of this, but at the end of the day, you need to understand what it means, because that’s where the surprises hit.

If the soil’s bad, it’s an extra cost. If the drainage is complicated, that’s also an extra cost. And if the overlays are restrictive, you’re looking at more time… which results in more cost.

Pre-Build Phase 3: Design & Team Selection

Now that you know the site works for you, it’s time to lock in your team and begin the design process.

At this point you can work with an architect, a building designer, or you can even go straight through your chosen builder and use their plans, whatever suits the style of home you are looking for and the way you prefer to work.

But no matter which path you take, the design still must comply with the National Construction Code, your local planning rules, and of course, your budget.

Choosing the Right Builder for Your Project

And this is also the time to choose your builder, not at the end but right now.

When working out how to choose a builder, look for strong communication, transparent pricing, and a genuine track record of building homes like the one you are planning.

If your block has development potential, that experience matters even more, which is where engaging dual occupancy builders or duplex home builders becomes important, as multi-dwelling projects come with different design, compliance, and cost considerations compared to a standard single home.

You need a builder that uses industry-recognised contracts, such as Master Builders or HIA here in Victoria, and you need someone who isn’t cutting corners just to win the job. If you get a crazy cheap price relative to other tenders, that should be seen as a red flag, not a bargain.

At the end of the day, your team will directly impact your experience. So choose well.

And if your plan involves building more than one dwelling, such as townhouses, it’s critical to work with townhouse builders who understand higher-density design, sequencing, and approvals, as the margin for error tightens significantly once complexity increases.

This is also the point where your windows and external doors get fully specified and measured, so your builder can order them early.

You want these ordered well before construction begins so they’re ready to be installed at lock-up,
delays here can stall the entire build.

Pre-Build Phase 4: Approvals, Permits & Documentation

The next step is to think about the approvals, permits and documentation you will need to execute your build. This is where most people get blind sided.

Before you build anything, there’s a stack of approvals and documents you need to have locked in. You’ll need your planning permit if your project requires one, and you’ll need your building permit, all your engineering drawings and computations, your energy report, soil tests, final working drawings, and your full contract documentation.

If something is missing or incorrect here, it will cause delays later, guaranteed.

This is also the stage where you confirm every inclusion and every exclusion.

And before you pay your deposit, make sure the builder has actually taken out their domestic building insurance and shown you proof of it.

It is not uncommon for builders with financial issues to collect the deposit before lodging the insurance, and if they go under, that deposit isn’t covered. So when you sign the contract, wait for the insurance certificate, check it, and only then pay your deposit.

It’s also critical you minimise or, even better, remove all assumptions from your build contract as practically as possible by accounting for all your costs, and of course, agreeing to a fair and reasonable timeline with your builder.

It is important that once you agree to that timeline, you lock in what is called fair liquidated damages in your contract, which is essentially how much the builder needs to pay you per week for every week they are delayed.

The more clarity you get right now, and the more assumptions you can replace with actual pricing, the smoother the entire build is going to run. A small amount of time spent now will save massive time and money later.

Stage 1: Base Stage

This is the first construction stage in Victoria, and this is where your first progress payment is typically due. For full context, you would have already paid your 5% deposit when you signed your build contract.

Next is what is called the base stage, so where the physical work onsite begins. It entails your site preparation and your slab.

Your surveyor goes out first to your block to do the site set-out, using the site surveys. They are literally marking where the house is going to sit on the block.

After that, all the underground work gets underway. The plumbers run everything that needs to go in under the slab, the footings get excavated, and the formwork gets set up, so the slab can be poured.
Once you get to this point, and it has been completed, your build should start to move quickly.

Stage 2: Frame Stage

Completion of this stage triggers the second progress payment.

After the slab cures, the carpenters come in and set out the walls directly on top of the slab.

From there, the frames start going up. Most of the time they’re prefabricated offsite and then craned in, which makes this part move quickly.

After the frames are in, you’ll see the rest of the structure take shape. The structural steel beams go in, as well as the posi-struts for the second-floor support. The upper-floor frames, and the wall insulation wrap, also known as sisalation. And then the roof trusses, along with the fascia, the gutters, and the roof sheets.

This is the point where your house starts looking like a house for the first time.

And before the roof goes on, the builder needs to install the scaffolding and all the fall-protection measures. So the roof plumber can work safely.

Stage 3: Lockup Stage

This is the third recognised stage, and builders typically claim the next progress payment here.

Next is where you are looking to complete what is called the lock-up stage.

At this point, you will have arranged delivery of the windows and external doors you ordered earlier in the process so they can be installed. Once they’re in, the house becomes weatherproof.

This is lock-up.

Stage 4: Fixing Stage

Completion of this stage triggers the fixing-stage payment claim. At this point, you move into what’s called the fixing stage.

This is where the carpenter comes through and starts installing all the internal details. So the doors, handles, skirting, architraves, and the internal fixtures.

Once that’s done, the painter will usually come in and put on the first coat. And from there the kitchen and joinery measurements are finalised, so the joinery can be manufactured offsite.

This step matters. If anything goes wrong here, your finish quality will suffer.

Stage 5: Completion Stage

Includes Fit-Off & Finishes and Final Checks. This is the final construction stage under Victorian law, and it aligns with the final payment claim.

Fit Off & Finishes (now correctly part of Completion Stage). Then it’s time for the final fit-off and all your finishes. This is the stage where the home actually comes alive.

Inside, your kitchen and bathroom joinery gets installed. Your stone bench tops go in, and the plumbers fit off all the taps and fixtures.

The electrician fits the switches, the power outlets, and the lights. Your heating and cooling get commissioned, so everything is balanced and working properly, and then your flooring goes in.

Externally, the driveway gets done, any paths get installed. The turf goes down, the garden beds are finished, and the fences go up. Even the clotheslines and letterboxes get installed.

Once again, all of this can happen in parallel. Final Checks, Compliance & Handover.

Certificate of Occupancy

Now we’re at the pointy end of the project. Once everything is complete, your building surveyor will come through and sign off on any compliance items.

After that, the Certificate of Occupancy is issued by the building surveyor. This document confirms the home is safe, compliant, and ready to be lived in.

You and the builder will then do a full walkthrough. A defect list will be created. And this is your chance to identify anything that needs to be fixed before the final handover. The builder will fix those items, and once that’s all sorted, you get handover.

This is the moment your project officially becomes a home.

And if you’re subdividing your property. Your council will issue your Statement of Compliance once all the subdivision requirements have been met. That includes things like services being connected. Driveways being completed, and any other conditions set out in your planning permit are being signed off.

Once the council issues that Statement of Compliance, you can lodge your titles and settle any off the plan sales you made.

Post-Build: After You Move In

At this point, if the plan is to move in, then it’s game on. You can move in, just keep in mind you’ll have a defect’s liability period, usually somewhere between three and twelve months, depending on your contract.

During that time, you want to keep an eye on anything unusual, things like cracking, doors sticking, leaks, or electrical issues. If anything like that shows up, make sure you note it down.

Your builder must return and fix any genuine defects. That’s what the defects liability period is there for.

That’s it, so if you’re thinking about building your first home in Australia, I hope this gave you the clarity you need to do it with confidence.
