Renovation cost on the Sunshine Coast is one of the first things homeowners want to know, and it is also one of the hardest questions to answer with a single number. The honest truth is that a fair price depends on scope, finishes and structural work far more than it depends on the postcode. Here is what the real market ranges look like in 2026, and what actually moves the number up or down.
Why Renovation Cost Varies So Much
No two renovations are the same, even when the square metreage matches. A cosmetic refresh, a full structural renovation and a premium whole home renovation sit at completely different price points, because the work involved is fundamentally different. Removing a wall, relocating plumbing, or adding a second bathroom all add cost in ways that square metre figures alone do not fully capture.
Renovation Cost Sunshine Coast: What the Market Looks Like in 2026
Based on current Queensland market data, renovation cost Sunshine Coast homeowners can expect generally falls into these bands:
- Cosmetic refresh (paint, fixtures, surface updates): roughly $1,500 to $3,000 per square metre
- Standard structural renovation (wall removal, layout changes, new plumbing runs): roughly $3,500 to $5,500 per square metre
- Premium whole home renovation (high end finishes, extensive structural work): $5,500 per square metre and upward
These figures move around depending on your specific home, so treat them as a starting point for conversation, not a final number.
Extension Cost: How It Compares
Extension cost in Australia generally sits between $2,000 and $4,000 per square metre for a ground floor addition, depending on scope and finishes. Second storey additions cost more per square metre than ground floor extensions, since they involve structural engineering, temporary roof removal and often a new staircase, all of which ground floor work simply does not need.
If you are still weighing up renovation against extension for your own home, cost is often the deciding factor, and the right answer depends on whether your existing layout or your available space is the real constraint.
What Drives the Price Up (and Down)
A handful of factors explain most of the difference between the low end and the high end of any renovation cost range:
- Structural changes, such as removing load bearing walls or altering rooflines, add engineering and construction cost
- Wet areas, including kitchens, bathrooms and laundries, cost more per square metre than dry living spaces due to plumbing, waterproofing and fixtures
- Site access, particularly on sloped Hinterland blocks or tighter coastal lots, can add cost through equipment access and material delivery
- Finish level, from standard fixtures through to premium joinery and stone, has one of the biggest impacts on the final number
How to Budget Realistically for Your Project
Rather than fixating on a single per square metre figure, build your budget around the scope of work you actually want, then add a contingency of at least 10 to 15 percent for the unexpected. Older Sunshine Coast homes in particular can hide issues behind walls that only become clear once work begins, and a realistic budget accounts for that from the outset rather than treating it as a nasty surprise later.
Getting an Accurate, Fixed Price Quote
A generic per square metre figure is a useful starting point, but it is never a substitute for a proper quote based on your actual home. The Queensland Building and Construction Commission requires licensed builders to provide clear, itemised contracts for renovation work above certain thresholds, which is exactly why a fixed price quote from a licensed builder gives you a far more reliable number than any online calculator.
If you already have a sense of the scope you want, whether that is a full renovation or a second storey addition, a site inspection is the fastest way to turn a market range into a number you can actually plan around.
Frequently Asked Questions
How much does a renovation cost per square metre on the Sunshine Coast?
As a general market range in 2026, cosmetic renovations run roughly $1,500 to $3,000 per square metre, standard structural renovations $3,500 to $5,500, and premium whole home renovations $5,500 and upward. Your actual cost depends on scope and finishes.
Is an extension cheaper than a full renovation?
Not always. A small extension can cost less than a large full home renovation, and a modest renovation can cost less than a small extension. Scope and square metreage matter more than which category the project falls into.
Why do quotes for the same size renovation vary so much between builders?
Differences usually come down to what is included, the quality of materials specified, and how much contingency is built in. A detailed, itemised quote is always more reliable than comparing bottom line numbers alone.
Should I budget extra beyond the quoted price?
Yes. A contingency of 10 to 15 percent is standard practice, particularly for older homes where hidden issues behind walls or under floors are common once work begins.
