Renovation programs fail on the Gold Coast for reasons that are largely local. The wet season stops external work. The Christmas and school holiday periods shut down apartment buildings for renovation work entirely. Tidal works permits take months. Body corporate meeting cycles add quarters, not weeks. And a large share of projects need reports — coastal, flood, geotechnical, acid sulfate — that nobody commissioned until the council asked for them.
This guide sets out how long each stage actually takes here, where the time goes, and what can and cannot be compressed.
The Headline Numbers
End to end, from first sketch to moving back in:
- Bathroom renovation, house: 2 to 4 months total, 4 to 6 weeks on site
- Bathroom renovation, apartment: 4 to 8 months total, 6 to 10 weeks on site
- Kitchen renovation: 3 to 6 months total, 6 to 10 weeks on site
- Full internal renovation, no structural change: 7 to 11 months total, 3 to 5 months on site
- Renovation plus ground-floor extension: 13 to 20 months total, 5 to 9 months on site
- Second-storey addition: 18 to 26 months total, 9 to 15 months on site
- Canal-front project including revetment wall or pontoon: 18 to 30 months total
The construction period is usually less than half the total.
Stage One: Design and Documentation
- Bathroom or kitchen: 2 to 4 weeks
- Internal renovation: 4 to 8 weeks
- Extension: 8 to 16 weeks
- Architect-designed or complex site: 12 to 26 weeks
What controls the duration is almost entirely you. The most common cause of design running long is a client taking three weeks to review each iteration and then changing direction at the fourth. Set a decision rhythm — drawings out Friday, comments back Wednesday — and hold it.
Stage Two: Investigations
These run largely in parallel with late design, but on the Gold Coast there are more of them than in most cities, and missing one is the classic cause of an application stalling.
- Soil test and site classification: 1 to 2 weeks
- Detail survey: 1 to 2 weeks
- Structural engineering: 2 to 5 weeks after design is settled, longer where wind loading and coastal conditions drive the design
- Energy rating assessment: 1 to 2 weeks
- Flood or hydraulic assessment where a flood or storm tide overlay applies: 2 to 4 weeks
- Coastal engineering assessment on beachfront sites: 3 to 6 weeks
- Acid sulfate soil investigation where excavation is triggered: 2 to 4 weeks
- Bushfire assessment in the hinterland: 1 to 3 weeks
- Geotechnical assessment on steep or landslide-affected land: 3 to 6 weeks
- Marine engineer’s revetment wall assessment on canal properties: 2 to 4 weeks
Commission the ones your overlays require before lodgement. A council information request for a report you have not started is a two to three month delay.
Stage Three: Approvals
Development approval
- Accepted development — no development approval required, but building approval still is
- Code assessable: commonly 6 to 14 weeks, substantially longer if an information request is issued
- Impact assessable: 4 to 8 months including public notification and the appeal period
Building approval
Through a private building certifier, typically 2 to 6 weeks. Engage the certifier early — at concept, not at lodgement — because they will identify wind loading, floor level, fire separation and energy issues while those are still cheap to fix.
Tidal works permit
2 to 6 months. Reviewed by the Gold Coast Waterways Authority with the City of Gold Coast as assessment manager. Required for pontoons, jetties, boat ramps, rock armouring, revetment walls and dredging. This is the single longest approval item on a Gold Coast waterfront project and it should be lodged first, not last.

Body corporate approval
2 weeks to 4 months. Committee approval can be quick; anything requiring a general meeting resolution waits for the meeting cycle. In a Gold Coast tower this is frequently the longest single item in an apartment renovation program.
Stage Four: Tender and Contract
- Preparing the tender package: 1 to 2 weeks
- Builders pricing: 3 to 6 weeks. Good builders will not price a complex job in a week.
- Comparing and clarifying: 1 to 2 weeks
- Contract negotiation: 1 to 2 weeks
- Waiting for the builder’s start date: 6 to 20 weeks for anyone worth having
That last line is what people forget. A good Gold Coast renovation builder — particularly one who works on canal or beachfront sites — is booked several months ahead.

Stage Five: Construction
A ground-floor extension plus internal renovation, week by week
- Weeks 1–2: Site establishment, protection, demolition, waste removal, asbestos removal and clearance
- Weeks 3–5: Excavation, acid sulfate management if triggered, piled footings, engineer inspection, pour
- Weeks 6–8: Slab or suspended floor, structural steel
- Weeks 9–13: Framing, termite management, roof structure and roof covering. Weathertight at the end of this block — the first real milestone, and in the wet season the one that matters most.
- Weeks 14–17: Windows and external doors, external cladding or brickwork
- Weeks 18–21: Services rough-in — plumbing, electrical, data, air conditioning
- Weeks 22–24: Insulation, internal lining, plaster set
- Weeks 25–28: Waterproofing with proper curing between coats, then flood test. In summer humidity this block runs longer than the data sheet suggests.
- Weeks 29–33: Tiling, internal carpentry, doors, skirtings
- Weeks 34–36: Joinery install, then stone template, fabrication and install
- Weeks 37–39: Painting
- Weeks 40–42: Flooring, plumbing and electrical fit-off, appliances, screens and mirrors
- Weeks 43–45: External works, landscaping, certifier’s final inspection, Form 21, defects and handover
Where the Time Disappears
Procurement lead times
- Windows and external doors: 8 to 16 weeks, and longer for marine-grade or wind-rated systems, which are frequently not stock items. The most common cause of a stalled Gold Coast build.
- Kitchen and joinery: 4 to 10 weeks from sign-off
- Stone benchtops: 10 to 15 business days from template to install, and the template cannot happen until the cabinets are in
- Imported tiles: 6 to 14 weeks
- Imported appliances and tapware: 4 to 20 weeks
- Structural steel: 3 to 7 weeks
- 316 stainless connectors and specialised marine hardware: often not stock, allow 3 to 8 weeks
- Pontoons: 8 to 16 weeks manufacture after the tidal works permit issues
Weather
This is the Gold Coast’s biggest program variable and the one most often left out.
- The wet season, broadly December through March, brings intense rainfall, storms and hail. Excavation, footings, roofing, external cladding and painting all lose days.
- A house that is not weathertight when the wet season starts can lose four to eight weeks. Sequencing the roof before December is the single most valuable program decision on a Gold Coast build.
- Summer humidity extends curing times for concrete, membranes, adhesives, grout and paint.
- Extreme heat days restrict roofing and external work for safety.
- Cyclonic or severe weather events occasionally cause trade shortages afterwards, as everyone is pulled onto emergency repairs.
The holiday shutdown
The industry closes from around mid-December to mid or late January. Separately, many Gold Coast apartment buildings prohibit renovation work during peak holiday periods — Christmas, Easter and school holidays — because of the short-stay occupancy. In a heavily let building this can remove eight to twelve weeks a year from your available program. Check the by-laws and the building’s calendar before setting any dates.
Client decisions and variations
Every unmade decision becomes a stop, and every variation costs time to price, approve and build, and usually breaks the trade sequence. A job with fifteen variations runs measurably longer than the same job with two.
Gold Coast-Specific Delays
- Termite damage discovered on demolition. Common in timber-framed stock. Two to five weeks of structural repair plus treatment.
- Asbestos, near-universal pre-1990. Three to seven days including licensed removal and clearance.
- Concrete spalling found on a balcony. Two to six weeks of structural repair before the membrane can go down.
- Footing redesign after the soil test comes back worse than assumed. Two to five weeks.
- Acid sulfate management triggered by excavation depth. One to three weeks and a real cost.
- Corroded structural fixings discovered when a deck or roof is opened up.
- Body corporate meeting cycles in apartment work.
- Tidal works permits on waterfront projects.
- Council information requests for reports the overlays required and nobody commissioned.
What You Can Compress
- Commission every overlay-driven report before lodging. The single largest lever on a Gold Coast program.
- Make every decision before construction starts.
- Order long-lead items early — windows especially, and marine-grade hardware — before site works begin.
- Lodge the tidal works application first on any waterfront project.
- Start the body corporate approval process immediately in apartment work, and find out the meeting cycle before you plan anything.
- Engage the certifier at concept stage.
- Design to accepted development where you sensibly can, and avoid a development application entirely.
- Sequence to be weathertight before December.
- Move out for the intensive phase. Commonly saves 15 to 25 per cent of the construction period.
- Choose materials that are in stock rather than the ones with a sixteen-week lead time.
What You Cannot Compress
- Statutory assessment periods and the tidal works process
- Body corporate meeting cycles
- Concrete curing, membrane curing and paint drying — all longer here in summer humidity
- Manufacturing lead times once the order is placed
- Trade availability in a busy market
- The wet season
- The physical sequence of construction
Living Through It
- Add 20 to 25 per cent to whatever program you are given and plan your life around that number
- If you are staying in the house, set up a functional temporary kitchen and confirm which bathroom stays operational and for how long
- Take a rental with a flexible end date, never a fixed one against a construction program
- Do not book the sale campaign, the housewarming or a family Christmas against the contract completion date
- Expect the last 10 per cent to take 25 per cent of the time — fit-off and defects always run long
- In an apartment, tell the neighbours the program in advance and keep them updated. Goodwill is what gets you through a job that runs over.
A realistic program is not pessimism; it is the difference between a project that feels controlled and one that feels like it is happening to you. On the Gold Coast, the two decisions that matter most are commissioning the reports before lodgement and being weathertight before the wet season starts.

Building a Program You Can Hold To
A program is only useful if it is honest, and most renovation programs fail because they were written as a best case and then treated as a commitment.
How to construct it
- Start from the finish date you need and work backwards. This immediately reveals whether the project is feasible in the time available.
- Identify the critical path. On a Gold Coast project it usually runs through overlay reports, soil test, footing design, development approval, building approval, builder availability, piling, frame, roof, services rough-in, waterproofing, tiling, joinery, stone, fit-off — with tidal works and body corporate approval sitting on it where relevant.
- Put long-lead items on the program as orders, not deliveries. Marine-grade windows ordered in week four arrive in week eighteen.
- Add float in blocks, not per task. Three weeks after approvals and four weeks before the finish date is more useful than three days sprinkled across forty activities, because sprinkled float gets consumed invisibly.
- Mark the immovable dates — the wet season, the Christmas shutdown, apartment building holiday restrictions, a lease expiry.
- Review it fortnightly with the builder against actual progress, not intended progress.
Early warning signs
- A trade did not start on the booked day and no replacement date has been given
- A variation has been discussed but not priced
- A long-lead item has not been ordered by the week the program says it should have been
- The site is quiet for more than three consecutive working days without explanation
- A selection is still open two weeks before the trade needs it
- An approval condition has been received but not actioned
- A report the council has requested has not been commissioned
Each is recoverable if caught in the week it happens and expensive a month later. The owner who walks the site weekly and asks one question — what is the next thing that needs to happen, and is it booked — recovers most of them.
Working Around the Wet Season
Nothing shapes a Gold Coast construction program more than the December to March period, and it is the variable most often left out of a builder’s optimistic estimate.
What stops
- Excavation and footings, which cannot proceed in saturated ground
- Concrete pours, both in heavy rain and on extreme heat days
- Roofing and external cladding
- External painting
- Landscaping and paving
- Any crane or elevated work in high wind
What slows
- Concrete, membrane, adhesive, grout and paint curing, all extended by sustained humidity
- Internal work in a building that is not weathertight, because everything gets wet
- Trade availability after a severe weather event, when everyone is pulled onto emergency repairs
How to plan around it
- Sequence to be weathertight before December. Roof on, windows in. This is the most valuable single program decision available on a Gold Coast build, and it is worth accepting a later start to achieve it.
- Do the wet-season months internally. Services rough-in, linings, tiling, joinery — all of it proceeds under a roof.
- Push landscaping and external painting to April.
- Add four to eight weeks of float to any program that has external work scheduled through the wet months.
- Protect the site properly. Temporary weather protection, adequate site drainage and materials stored off the ground are cheap against a week of rework.
