THIS IS THE WORST WAY TO START YOUR RENOVATION (AND THE EASIEST WAY TO BLOW YOUR BUDGET)
Have you ever tried icing a cake before it’s cooled? For a second it looks perfect… then the icing melts, the whole thing collapses, and the effort you put in ends up wasted, smeared across the bench.
Most people would never do that in the kitchen. But in renovations? It happens all the time.
In fact, it’s exactly how most renovations begin. And it’s a big part of why so many never get built.
See, most homeowners begin their renovation the same way.
They sit down with a designer, sketch what they want, pour over beautiful drawings, and start imagining how the new space will feel. It’s an exciting stage full of momentum, creativity, and optimism that makes you think,
“Yes, this is finally happening.”
But this is the moment things quietly go off track.
Because even though the plans look polished, so much of what matters hasn’t been decided yet. Things that dramatically change the real-world cost of a build.
And in my experience, it almost always comes down to these five missing factors:
Factor #1: The Structure That Holds Everything Up
When you look at a set of drawings, it’s easy to assume the hard decisions are already made. You can see the rooms, the walls, the beams, and the openings, so it feels like the structure is sorted.
But, the drawings only show the layout, not how that layout will actually stand up.
Things like span lengths, load paths, bracing, beams, and lintels all dictate how complex the build will be, how much labour it needs, and what materials are required to make it safe and compliant.
If those details aren’t worked out early, you’ll pay for it later.
Factor #2: The Materials Your Home Will Actually Be Made From
Most drawings only show the shape of the home, not what it’s made from. But the difference between basic aluminium windows and high-performance ones, or between a standard wall wrap and a breathable system, changes both cost and comfort dramatically. Until materials like windows, insulation, wraps, cladding, and flooring are chosen, every builder is pricing a different version of your renovation, and that’s where budgets drift fast.
Factor #3: How Things Are Installed
(Which Varies Wildly Between Builders)
One thing drawings never show is how something is put together, and the method matters just as much as the material itself. The preparation, sequencing, and installation technique can change the time, labour, and complexity of a job more than most people realise.
For example:
A window that “fits” on paper may require completely different framing or waterproofing depending on the system chosen
A simple cladding line might need extra battens, sarking, or ventilation to perform properly
And some products look identical in drawings but require hours more labour to install safely and correctly
When the installation method isn’t defined early, every builder is pricing a different process, and that’s why your quotes can feel like they’re for three different projects.
Factor #4: What Your Site Actually Allows Or Restricts
Drawings assume a perfect environment: flat ground, easy access, plenty of room to work. But your actual site rarely behaves that way. The slope, space, entry points, neighbouring properties, and even the street you live on all influence how the renovation can be built.
Not only that, but it also determines whether materials can be carried in by hand or need machinery, whether scaffolding or cranes are required, and how efficiently trades can move around the space.
None of this appears on your drawings, but it all affects cost, time, and method.
Factor #5: The Level Of Performance You Expect (Or Assume)
Two renovations can look identical on paper but perform completely differently in real life, and that comes down to the performance standard you’re aiming for. Some builders price the minimum required to meet code, while others allow for better insulation, healthier wall systems, higher-performing windows, or more durable construction methods.
None of that shows up in the drawings, yet each choice affects comfort, air quality, longevity, and how much you’ll pay.
Bottom Line: When you add all of this up, it becomes clear why drawings alone can’t give you an accurate price. Until the structure, materials, installation method, site constraints, and performance level are all decided, every builder is working off a different set of assumptions.
This is also why the order you start the process in matters more than most people realise.
Because if protecting your budget is the priority, the builder needs to be involved long before the drawings are finalised.
Why Your Builder Should Be Involved From Day One
When a builder is involved early, you’re designing with real-world information from the start. The structure, materials, installation methods, site constraints, and performance expectations get worked out as you design, so you’re never hit with surprises down the track.
It’s the only way to remove the assumptions that normally blow budgets apart. Because when everyone is working from the same details, at the same time, and with the same understanding of what your renovation actually needs, you’re creating something you can build, not something you’ll have to scale back later.
If You Start In The Wrong Place, Everything Else Shifts With It
Renovations don’t fall apart because people lack vision. They fall apart because the first step is taken out of sequence, and everything that follows is built on top of assumptions instead of facts.
But when the builder is involved from day one, the design, the cost, and the reality of the build stays connected. You know what you’re choosing, what it affects, and what it really costs. And the plans you fall in love with are the plans you can actually build.
Of course, there’s a lot more that goes into renovating your home than doing it in the right order. That’s why I’ve created this free guide for you to download:

We can walk you through what really matters, what to look out for, and how to set your renovation up the right way from the very beginning.
Whether you choose to build with us or not, we’re here to help you start in the right place.
FAQs
-
Budget blowouts almost always come from one thing: assumptions made too early.
Drawings alone don’t define structure, materials, installation methods, or site constraints — all of which shape the real cost.Through our PAC Process (Paid-As-Consultant), we work through every detail upfront so your pricing is grounded in facts, not guesswork.
The number you receive is one you can rely on. -
It doesn’t have to be.
A renovation feels stressful when communication is unclear, details are missed, or decisions are made in the wrong order.We prioritise a calm, guided experience with clear updates, structured decision-making, and transparency at every step — so you always know what’s happening, why, and what it means.
