Scroll through any builder’s marketing material and you’ll see timelines that sound almost too good to be true: move in within six months, keys in your hand before the year is out. For some straightforward builds on flat, serviced land, that’s genuinely achievable. For most people, though, the real timeline looks quite different once you account for approvals, weather, supply delays, and the sheer number of trades that need to move through a site in sequence.
Understanding what actually happens at each stage of a build, and roughly how long it takes, makes it much easier to plan around a real move in date rather than a marketing one.
Setting Realistic Expectations From the Start
Before committing to any builder, it’s worth asking how they structure their published timelines and what’s typically included in that estimate. Some quote from the day the slab is poured, others quote from contract signing, which can make two “six month” timelines mean very different things in practice. Comparing how different builders present this, whether you’re speaking to a smaller local operator or looking to build with Stand Out Projects, gives you a clearer sense of what a realistic timeline actually looks like for your specific project rather than a generic average.
Ask specifically what stage the clock starts at, and ask for examples of recent projects with actual completion dates, not just projected ones.
Pre Construction: Approvals and Permits
This is the stage most people underestimate, largely because it happens before any visible work starts on site. Council approvals, soil testing, and engineering assessments typically take anywhere from four to twelve weeks, and longer in council areas with high application volumes or if your block has any complicating factors like easements, overlays, or bushfire zoning.
Custom designs generally take longer here than standard plans, since engineering has to be assessed from scratch rather than pulled from an already approved template. This stage rarely gets media attention because there’s nothing to photograph, but delays here push everything else back.
Site Works and Slab
Once approvals are through, site works begin: clearing, levelling, and preparing the block for the foundation. For a standard block this typically takes one to two weeks, though sloping or reactive clay sites can take considerably longer due to additional engineering requirements for the footing system.
Weather plays a real role here too. Concrete pours need dry conditions, and a run of wet weather during Melbourne’s cooler months can push this stage back by a week or more without anyone doing anything wrong.
Frame to Lockup
This is usually the stage that feels the fastest, and it’s often the one shown in time lapse videos because visible progress happens quickly. From frame to full lockup, meaning external walls, roof, windows, and doors are in, typically takes around six to eight weeks for a standard single storey home, longer for double storey or architecturally complex builds.
It’s also the stage where a home first starts to look like a house rather than a construction site, which is why many buyers feel most optimistic about timelines at this point, sometimes prematurely.
The Fixing Stage
This is where timelines most commonly slip, and it’s the longest stage of the build by a meaningful margin. Electrical, plumbing, cabinetry, tiling, painting, and flooring all need to happen in a coordinated sequence, and a delay in one trade, a cabinetry supplier running behind, an electrical inspection needing to be rebooked, ripples through everyone scheduled after them.
Depending on the complexity of finishes and the availability of tradespeople, this stage can take anywhere from twelve to twenty weeks. Custom finishes, imported materials, or high demand periods for trades can extend this further.
Handover and Final Inspections
The final stretch involves a formal inspection process, a defects walkthrough, and any last minute rectification work before keys are handed over. Minor defects at this stage are normal and expected, but the time needed to fix them, and how quickly a builder responds, varies considerably.
This stage is often quoted as a week or two, but if defects are significant or the builder has a backlog of handovers, it can stretch out further than buyers expect.
Planning With Buffer Time
Given how many stages depend on the one before it, and how many are exposed to weather, supply, and approval delays outside anyone’s direct control, it’s sensible to plan around a timeline that’s several weeks longer than whatever you’re initially quoted. If you’re timing a lease end date or bridging finance around a build, build in that buffer deliberately rather than assuming the fastest case scenario. A realistic timeline, understood in stages, makes for a far less stressful build than one measured against a headline figure that was never quite achievable in the first place.
