The most common question we hear before a homeowner signs a contract is: how long will this actually take? The honest answer depends entirely on the scope of work, your council consent requirements, and how well your builder manages their programme.
Here are real timelines based on 200+ Auckland renovation projects completed by Add Value Renovations — not industry averages from a brochure.
Bathroom Renovation: 5–8 Weeks On Site
A standard bathroom renovation in Auckland takes 5 to 8 weeks on site from the day demolition starts to the day you walk back in. The range depends on the size of the bathroom, whether plumbing is being relocated, and whether waterproofing needs a separate council inspection.

- Week 1–2: Demolition, rough plumbing relocation, framing changes
- Week 2–3: Waterproofing, liner installation, waterproofing inspection (allow 5 working days for council to inspect)
- Week 3–5: Tiling, wall linings, floor
- Week 5–7: Fixtures, vanity, shower fittings, finishing
- Week 7–8: Final fix, painting, punch list
What slows bathrooms down: Tile lead times (allow 3–4 weeks for imported tiles), waterproofing inspection wait times, and late decisions on fixtures. Order everything before demolition starts.
Kitchen Renovation: 7–12 Weeks On Site
A kitchen renovation takes longer than most homeowners expect — primarily because custom joinery takes 6–8 weeks to manufacture. The on-site work is only part of the timeline.
Full kitchen timeline including lead time:
- Weeks 1–3 (design phase): Design sign-off, joinery order placed
- Weeks 3–9 (joinery manufacturing): On-site prep work begins (electrical rough-in, plumbing, structural changes)
- Weeks 9–12 (installation): Joinery delivered and installed, benchtop templated, splashback, appliances connected
- Weeks 12–14 (finishing): Painting, hardware, final connections
Total elapsed time from design sign-off to completion: 12–16 weeks for most Auckland kitchens.
Multi-Room Renovation: 12–20 Weeks On Site
If you are renovating multiple rooms simultaneously — a kitchen plus bathrooms, or bedrooms plus a living area — the timelines overlap but the project complexity increases. Expect 12 to 20 weeks on site depending on scope, with careful sequencing of trades to avoid delays.
Multi-room projects usually require building consent, which adds 4–8 weeks to the overall programme. Apply for consent during the design phase so approval arrives before you need to start on site.
Full Home Renovation: 3–6 Months On Site
A full home renovation — every room, structural changes, possibly a reconfigured floor plan — takes 3 to 6 months of on-site work. Where your project sits in that range depends on:
- The extent of structural work (wall removal, beam installation, foundation changes)
- Whether you are staying in the house (adds time for sequencing to preserve habitable areas)
- Consent complexity (some full renovations require multiple consent types)
- Finishing specification (custom joinery, imported tiles, and specialist finishes all take longer)
Most of our full home renovation clients in Auckland are out of the house for 14–22 weeks. Plan your temporary accommodation around that window.
Home Extension: 4–8 Months Total
Extensions — ground floor, second storey, or rear additions — have the longest timelines because they always require building consent and often structural engineering.
Extension timeline breakdown:
- Design and documentation: 4–8 weeks
- Building consent (Auckland Council): 20 working days once application is complete — but preparation of a complete application typically takes 2–4 weeks with your builder and engineer
- On-site construction: 12–20 weeks depending on size and complexity
- Code Compliance Certificate (CCC): Applied for after completion, issued within 20 working days
Total from design start to CCC: 6 to 10 months for a typical Auckland home extension.
How Building Consent Affects Your Timeline
Auckland Council has a statutory 20 working-day processing time for building consent applications — but that clock only starts once they have a complete application. An incomplete application gets returned, adding weeks to your timeline.
The most common consent delays in Auckland:
- Incomplete engineering documentation
- Missing site plans or as-built drawings
- Projects that require resource consent as well as building consent
- Applications lodged in December (council closes over Christmas)
A well-organised design-and-build company submits a complete application first time. Ask any builder you are considering: how many of your consent applications are returned for more information?
Seasonal Factors in Auckland
Auckland’s wet winters slow external work — foundations, framing and roofing all take longer in consistent rain. If your project has significant external work, a March start (into the dry months) is better than a July start.
December and January are the hardest months to staff a renovation site. Many subcontractors take 3–4 weeks off, and material lead times blow out. If your builder says they will start in December, understand what that actually means for on-site progress.
What You Can Do to Keep Your Renovation on Schedule
Builders are often blamed for delays, but homeowners cause more delays than they realise:
- Make selections early. Tiles, tapware, joinery handles, paint colours — decide these before work starts, not mid-build.
- Order long-lead items immediately. Some products take 10–16 weeks to arrive. Order the day you sign.
- Avoid scope changes once work has started. Every change triggers a variation, and variations take time to price, approve and schedule.
- Be available for decisions. Builders on site need answers quickly. Delays in responding delay the project.
- Trust the programme. A good project manager has sequenced the trades. Changing the sequence to accommodate a personal preference disrupts everyone downstream.
