How Much Should a Renovation Cost on the Gold Coast?

If you've typed "renovation cost" into Google at 11 p.m. with a half-finished mood board open in another tab, you're not alone. Every Gold Coast homeowner asks the same question before picking up a single paint swatch: what is this actually going to cost me? At CDC Construct, it's the first question every client asks in their initial consult, and it's the one most guides answer with vague ranges that don't hold up once a builder actually walks through your home.

This guide breaks down real renovation costs on the Gold Coast by room type, explains what pushes a quote up or down, and shows you how to budget so your project doesn't stall halfway through demolition.

Renovation cost on the Gold Coast typically ranges from $15,000 for a small bathroom refresh to $250,000+ for a full home renovation. Kitchens usually cost $20,000–$50,000, bathrooms $15,000–$35,000, and whole-home renovations $80,000–$250,000, depending on scope, finishes, and structural work.

Average Renovation Costs on the Gold Coast (2026)

The honest answer to "how much does a renovation cost" is: it depends on what you're renovating and how far you're taking it. But homeowners still need a starting point, so here's how the numbers typically break down across the most common project types we quote.

These figures reflect the kind of quotes we prepare for Gold Coast homes from Southport to Robina, and they shift based on finishes, access, and how much of the existing structure is being kept.

Pro Tip: Ask any builder near you for a fixed-price quote rather than a rough estimate before you commit to a start date — it's the single biggest safeguard against renovation cost blowouts.

What Affects Renovation Cost on the Gold Coast?

Two homes on the same street can renovate the same room for very different prices. Here's what actually moves the number.

• Scope and structural work – moving a wall, relocating plumbing, or changing a roofline costs far more than a like-for-like swap.
• Finishes and fixtures – stone benchtops, imported tiles, and custom joinery can double a kitchen renovation cost compared to standard fittings.
• Site access and slab type – elevated Gold Coast blocks near Burleigh or Currumbin, and older homes on stumps, often need extra engineering.
• Permits and QBCC compliance – council approvals and licensed trades add time and cost but protect the homeowner.
• Age of the home – older properties in suburbs like Southport or Mermaid Beach can hide asbestos, outdated wiring, or termite damage that only shows up mid-build.
• Trade availability – demand across the Gold Coast building market affects both pricing and lead times.

Did You Know?: A structural change as small as removing a load-bearing wall can add $5,000–$15,000 to the cost of renovating, once engineering, temporary support, and compliance are factored in.

Why Most Renovation Cost Guides Get This Wrong

Search "renovation cost" and you'll find plenty of national averages that don't reflect Gold Coast conditions. Three common problems show up again and again:

• Generic national figures – costs quoted for capital cities rarely match Gold Coast labour and material pricing, which run higher in peak building seasons.
• No allowance for hidden costs – asbestos removal, engineering reports, and council permits are often left out of "ballpark" estimates entirely.
• Treating quotes as fixed forever – material costs move throughout the year, so a quote from six months ago isn't a reliable guide today.

The result is homeowners who budget against a number that was never realistic for their suburb, their block, or their home's age – and then feel blindsided when a proper quote comes in higher.

What We See on Site

Working as a licensed QBCC builder across the Gold Coast, the renovations that stay on budget almost always share one thing: a detailed scope agreed before any demolition starts. The ones that run over almost always started with a rough sketch and a hope that pricing would sort itself out along the way.

Another pattern worth knowing: demand for whole-home renovations has grown faster than for extensions in recent years, as more owners choose to renovate in place rather than sell into a competitive Gold Coast market. That shift has made realistic, itemised budgeting more important than ever — not less.

Expert Recommendation: Get at least two itemised quotes before committing. A single lump-sum figure with no cost breakdown makes it almost impossible to compare renovation cost fairly between builders.

How to Budget for a Renovation

A workable renovation budget is built in this order:

• Define the scope – list every room and every change before pricing anything.
• Get 2–3 itemised quotes – compare like for like, not just the bottom-line total.
• Add a contingency – set aside 10–15% of the total cost of renovation for the unexpected.
• Separate must-haves from nice-to-haves – know which finishes you'd cut first if costs shift.
• Confirm payment stages – a licensed builder will structure payments against completed milestones, not upfront in full.

Quick Win: Locking in fixtures and finishes before the build starts — rather than deciding on site — is one of the fastest ways to keep renovation cost close to quote.

Common Mistakes That Blow Out Renovation Budgets

• Underestimating hidden costs like asbestos testing, skip bins, temporary accommodation, and council fees, which together can add thousands to the cost of renovating an older Gold Coast home.
• Changing the scope mid-build. Every variation request — even a small one — resets pricing and timelines.
• Choosing the cheapest quote without checking licensing. An unlicensed or underinsured operator can end up costing far more once defects surface.

Frequently Asked Questions

What is the average cost of renovating a bathroom near the Gold Coast?

A bathroom renovation near Gold Coast suburbs such as Broadbeach, Southport, or Helensvale generally costs $15,000–$35,000, depending on whether the layout changes and what tiling and fixtures are chosen.

How much do renovations cost per square metre?

Extensions and structural renovations are commonly quoted at $2,000–$3,500 per square metre on the Gold Coast, though this varies with site access and finish level.

Is renovation cost higher in Surfers Paradise or Robina than other Gold Coast suburbs?

Coastal and high-density areas like Surfers Paradise can carry higher renovation costs due to access restrictions and building regulations, while suburbs like Robina and Helensvale often see more standard pricing.

Do I need council approval, and does that affect renovation cost?

Most structural renovations and extensions on the Gold Coast require council approval. Permit and compliance costs are typically a smaller fraction of total renovation cost but should always be included in your budget from the start.

How long does a whole-home renovation take?

A whole-home renovation on the Gold Coast typically takes 3–6 months from approval to completion, depending on scope and how many trades are involved.

Getting a Renovation Cost You Can Rely On

Renovation cost on the Gold Coast isn't a single number — it's a range shaped by scope, finishes, and the condition of your home. The guides that quote one flat figure are guessing; a proper quote from a licensed builder is not.

CDC Construct has worked across Gold Coast suburbs from Broadbeach to Helensvale, and every quote we prepare is itemised, QBCC-compliant, and built around your actual home rather than a national average. If you're ready to find out what your renovation will really cost, CDC Construct can walk your site and put together a detailed, no-surprises quote.
