Whether you're updating a tired kitchen, converting a dated bathroom, or tackling a whole-home transformation, understanding realistic renovation costs is the single most important step before you sign anything. On the Gold Coast, costs can vary dramatically depending on scope, materials, site conditions, and the builder you choose. This guide is designed to give you honest numbers — not vague ranges pulled from national averages — so you can plan with confidence.
Overview of Renovation Costs on the Gold Coast
The Gold Coast sits in one of Queensland's most active building markets. Strong interstate migration, a booming population, and high demand for quality tradespeople mean renovation costs here tend to sit above the national average — but below Sydney and Melbourne. As a rough guide, you can expect to pay between $1,800 and $4,500 per square metre for a mid-range renovation, depending on the scope and finishes.
That said, “per square metre” figures only tell part of the story. A bathroom renovation in a 1970s brick home with asbestos sheeting and poor plumbing access will cost significantly more than the same scope in a modern slab-on-ground house. The specifics of your property always matter more than averages.
Cost Breakdown by Room
Kitchen Renovation: $15,000 – $50,000+
The kitchen is typically the highest-cost room to renovate, and for good reason — it involves plumbing, electrical, cabinetry, benchtops, splashbacks, and appliances. A cosmetic refresh (new doors, benchtop resurfacing, fresh paint) can come in under $15,000. A full gut-and-rebuild with stone benchtops, custom joinery, and premium appliances will push north of $40,000.
- Budget refresh (paint, handles, benchtop resurface): $8,000 – $15,000
- Mid-range (new cabinetry, stone benchtops, quality appliances): $20,000 – $35,000
- High-end (custom design, premium materials, structural changes): $40,000 – $60,000+
Bathroom Renovation: $10,000 – $35,000+
Bathrooms are deceptively expensive because of the waterproofing, tiling, plumbing, and ventilation requirements. On the Gold Coast, proper waterproofing to Australian Standard AS 3740 is non-negotiable — particularly in our humid subtropical climate where moisture issues compound quickly.
- Basic refresh (re-tile, new vanity, tapware): $10,000 – $18,000
- Mid-range (full strip, new layout, quality fixtures): $18,000 – $28,000
- High-end (freestanding bath, frameless glass, heated floors): $30,000 – $45,000+
Full Home Renovation: $50,000 – $200,000+
A full home renovation on the Gold Coast typically includes kitchen, bathrooms, flooring, painting, and often some structural work — opening up living areas, replacing windows, or upgrading the electrical switchboard. For a standard three-bedroom home, expect $80,000 to $150,000 for a comprehensive renovation with quality finishes. Larger homes or those requiring significant structural modifications can exceed $200,000.
Factors That Affect Your Renovation Cost
No two renovation projects are the same. Here are the primary factors that will move your budget up or down:
- Scope of work — A cosmetic update costs a fraction of a structural renovation. Be clear about what you actually need versus what you want.
- Material selections — The difference between laminate and natural stone benchtops can be $5,000 or more. Fixtures, tiles, and joinery all have wide price ranges.
- Site access — Steep blocks, narrow driveways, or multi-storey homes without lift access increase labour costs and project duration.
- Structural changes — Removing load-bearing walls, changing rooflines, or modifying floor levels requires engineering, council approval, and specialist trades.
- Council approvals — Building approval fees on the Gold Coast typically range from $1,500 to $5,000 depending on the scope. Some renovations may require a Development Application (DA), which adds time and cost.
Hidden Costs to Watch For
The costs that catch people off guard are rarely the tiles or the tapware — they're the things you can't see until you start pulling walls apart.
- Asbestos removal — Common in Gold Coast homes built before 1990. Licensed removal can cost $3,000 to $15,000+ depending on the extent. Under Queensland law, only a licensed removalist can handle asbestos-containing materials over 10 square metres.
- Council and compliance fees — Building certification, DA lodgement, plumbing compliance certificates, and final inspections all carry fees that add up.
- Temporary accommodation — For major renovations, you may need to move out for 4 to 12 weeks. Budget $300 to $600 per week for short-term rental or Airbnb.
- Landscaping and external works — Heavy machinery, skip bins, and trade vehicle access can damage driveways, gardens, and fences. Factor in reinstatement costs.
- Electrical and plumbing upgrades— Older homes often need switchboard upgrades, new circuits, or re-piping to meet current standards. These aren't optional once the walls are open.
How to Set a Realistic Budget
The best approach is to work backwards from what you can comfortably afford, not from a wish list. Here's a practical framework:
- Determine your total available budget (savings, equity, finance)
- Set aside 10–15% as a contingency — this is non-negotiable for any renovation
- Prioritise the rooms or areas that will have the greatest impact on your daily life
- Get a detailed, itemised quote from a licensed builder before committing to any material selections
- Be honest with your builder about your budget — a good builder will help you make smart trade-offs, not upsell you
A common mistake is spending weeks on Pinterest and Houzz before speaking to a builder. The finishes you fall in love with online may not suit your budget, your home's structure, or the Gold Coast climate. Start with a site assessment and work forward from there.
Why Fixed-Price Quoting Matters
One of the biggest sources of stress in any renovation is cost uncertainty. “Estimate” and “quote” are not the same thing. An estimate is a guess. A quote — particularly a fixed-price quote — is a commitment.
Under the QBCC (Queensland Building and Construction Commission) regulations, any residential building work over $3,300 requires a written contract. That contract should clearly specify the total price, inclusions, exclusions, and a realistic timeline. If your builder can't provide this, it's a red flag.
At JL Coastal Projects, every quote we provide is fixed-price and fully itemised. We walk through each line with you so there are no surprises. If something changes during construction — and sometimes it does — we discuss it with you before any additional work begins. That's how we believe building should work: transparent, honest, and on your terms.
If you're thinking about a renovation on the Gold Coast, we'd welcome the chance to have a conversation about your project. No pressure, no obligation — just honest advice from a team that builds here every day.
