How to Calculate Home Renovation Costs

I’ve been through a few renovation projects now and if there’s one thing I’ve learned, it’s this.
You don’t realize how fast costs pile up until you’re in the middle of it.
That’s why understanding the home renovations Mornington Peninsula budget early on is a life saver.

In Australia, people are renovating more than ever.
A report I came across recently showed renovation spending is expected to rise over 20 percent in the next few years.
It makes sense — folks are choosing to upgrade rather than pack up and move.

As someone working closely with SKB Construction, I’ve picked up a few smart ways to plan ahead — no fluff, just real numbers.

Why You Should Start with Numbers

Renovating your home isn’t just about design boards and mood lighting.
You need to know how much you’re working with.
The clearer your numbers, the easier your decisions.

I’ve seen people pause projects halfway through because they didn’t plan for hidden costs.
It’s painful.
A proper cost breakdown keeps you grounded from day one.

Step 1: Get a Rough Estimate First

One method that works well is using square meter pricing.
In Australia, average renovations sit somewhere between $2500 and $5000 per square meter.
That gap depends on finish level, materials, and how complex the work is.

If you’re updating paint and floors, you’ll sit at the lower end.
If you’re knocking out walls or adding new rooms, expect to land near the top.
For Mornington Peninsula homes, local labour rates can influence that too.

Step 2: Break It Down Room by Room

This helped me the most.
Kitchen? Bigger spend. Bathroom? Even more if plumbing’s involved.
A new kitchen in Australia can easily hit 40 to 50 grand. Bathrooms aren’t far behind.

Living areas and bedrooms usually cost less — think paint, carpet, lighting.
If you break your plan into parts, it’s easier to spot what’s eating up your budget.

Step 3: Don’t Forget the Professionals

If you’re using an architect or designer, they’ll add to the total.
Design fees can run between 5 and 15 percent of your budget.
But don’t skip this step just to save a few bucks.

I’ve seen clients pay more later to fix things that could’ve been solved with better planning.
Also, you may need permits or approvals — especially for structural changes.
In areas like Mornington Peninsula, some councils have specific requirements.

Step 4: Add a Buffer (Seriously)

If you think your project will cost $100,000 — be ready for $110,000.
Always, always add at least 10 percent for the unexpected.
Old plumbing, rotten frames, hidden wiring — I’ve seen it all.

It’s not about being paranoid.
It’s about being ready.
Trust me, your future self will thank you.

Step 5: Get Quotes — Real Ones

This is where a lot of people fall short.
Don’t rely on one quote or a quick guess from a mate.
Ask for three detailed ones. Breakdowns. Timelines. Materials.

When clients reach out to SKB Construction, we give them full clarity up front.
We don’t do surprises. And that’s exactly what you should expect from any builder.

Quick Example Budget

Let’s say you’re redoing a three-bedroom home.
Painting, flooring, new lights — you might spend 30 to 40K.
Toss in a full kitchen and bathroom update, you’re looking at 70K to 100K.

Want to extend the back of the house?
That could push the total near 200K or more.
But with better insulation, lighting, and resale value — it often pays off.

Cost-Cutting Tips That Still Work

Reuse what you can.
Keep layouts the same if you don’t need major changes.
Don’t rip out cabinets if they’re solid — just update the doors or handles.

And don’t cheap out on things like waterproofing or electrical.
Saving now might cost you more later.
Get advice, ask questions, stay involved.
