Bathroom & kitchen renovation costs
The two highest-ROI renovations in Auckland — typically returning 70 – 100% of cost in property value. The numbers, the drivers, and where smart spending pays off.
Bathroom Renovation
$25K – $90K+Standard family bathroom $25K – $35K. Tiled walk-in shower with underfloor heating and frameless glass: $35K – $60K. Luxury ensuite with layout change: $50K – $90K+. Tiled showers now need E3 internal moisture consent — adds $3K – $7K. Older Auckland homes carry hidden costs for asbestos, rot, and galvanised plumbing.

$30K – $200K+Like-for-like cabinetry and benchtop refresh: $30K – $50K. Mid-range renovation with stone benchtops, quality appliances, layout changes: $50K – $90K. High-end designer kitchen with custom cabinetry, scullery, premium European appliances: $90K – $200K+. Wall removal adds $20K – $80K but delivers the highest ROI.

Extensions in Auckland in 2026 run $4,500 – $7,500/m² depending on scope. The biggest cost drivers: ground-floor vs second-storey, site access, and whether recladding gets triggered.
Home Extension
$55K – $450K+A 20m² bedroom add-on: $55K – $90K. A 60m² ground-floor extension: $130K – $280K. A 70m² second-storey extension: $220K – $450K+. Multi-room extensions with kitchens and bathrooms sit at the upper end. Site access difficulty in inner-city suburbs adds 10 – 15% to labour costs.

$220K – $450K+A typical 60 – 80m² upper floor depending on the existing structure’s load capacity, roof and stair design, and consent complexity. Structural reinforcement of the ground floor — new piles, steel frames, or pile-and-beam upgrades — accounts for $40K – $120K of the budget on most projects.
Read the second-storey guideMaster Suite Addition
$120K – $250KA typical bedroom + ensuite + walk-in robe addition at the back of the home. Most popular Auckland extension type by far — adds liveable square metres, modernises the home, and consistently delivers strong resale uplift in school-zone suburbs.
Master suite extensions in AucklandGranny Flat / Minor Dwelling
$180K – $350K+Standalone granny flats up to 70m² now qualify under the consent exemption (effective 15 January 2026). LBP supervision required. Skipping consent doesn’t mean skipping quality — the build still has to meet Building Code.

The bigger renovation categories — where Auckland’s mid-1990s building era still drives a lot of work.
House Recladding
$150K – $500K+Single-storey timber-framed home, no structural damage: $150K. Two-storey monolithic-plaster reclad with framing remediation: $330K – $400K. Major rot or complex redesign pushes past $500K. University of Auckland research: weatherboard-reclad homes recover full market value; monolithic-reclad still attracts a 6% discount.
Read the recladding guideFull-Home Renovation
$400K – $2.5M+Mid-range full renovations on 150 – 200m² homes typically sit at $400K – $700K. Larger homes (200 – 300m²) at high-spec finish run $700K – $1.2M+. Add an extension or reclad and the total can push to $2.5M+ on character properties in premium suburbs.

$40K – $120KConverting an Auckland garage to a living room, home office, sleepout, or self-contained unit. Basic conversion (insulation, lining, flooring, basic electrical): $40K. Full kitchen and bathroom for a self-contained unit: $80K – $120K+. Building consent almost always required.

Premium suburbsCosts vary 20 – 30% across Auckland suburbs based on access, heritage overlays, and local spec expectations. Specific guides for Remuera, Ponsonby, and character-home renovations across Auckland.
Remuera renovation guideWhat makes Auckland renovation costs vary so much
The same renovation can vary 20 – 40% in cost between projects. The main drivers:
Suburb and site access
Narrow inner-city sites (Ponsonby, Grey Lynn, Kingsland) add 10 – 15% to labour costs. Suburban Auckland (Howick, Pakuranga, Albany) is cheaper to build on at the same spec.
Age of the home
Pre-1990 homes carry a 15 – 20% contingency for hidden issues: asbestos, borer, rot, galvanised plumbing, outdated wiring. Newer homes (post-2000) typically have fewer surprises.
Heritage & character overlays
Devonport, Mt Eden, Parnell, Remuera, Ponsonby, and Grey Lynn require resource consent for visible exterior changes — adding $10K – $30K in design fees and 8 – 16 weeks to the timeline.
Finish specification
Standard fixtures vs European appliances, natural stone, custom joinery, frameless glass can double the materials budget. Structural work doesn’t change — but visible finish does.
Structural complexity
Wall removal, foundations, re-piling, and structural beam additions need engineering input and specialist trades. Hidden structural prep is where most renovation surprises happen.
Design and consent path
Architect-and-tender model often costs 5 – 10% more than design-and-build, because of design revisions after build tenders come in over budget.
The real cost breakdown of a $300K renovation
Most clients are surprised by how much of a renovation budget goes to things they can’t see. A typical $300,000 Auckland renovation breaks down roughly:
| Line item | % of total | What it covers |
|---|---|---|
| Labour (all trades) | 35 – 45% | Builder rates, plumber, electrician, tiler, all subcontractors |
| Materials (visible finishes) | 15 – 25% | Tiles, fittings, cabinetry, paint, flooring, fixtures |
| Materials (structural & invisible) | 10 – 15% | Framing, gib, insulation, waterproofing, building wrap |
| Design and consent fees | 5 – 12% | Architect/designer, engineer, consent application, council fees |
| Project management | 5 – 10% | Coordinating trades, scheduling, supervision, communication |
| Contingency | 10 – 20% | Unforeseen structural, service, or compliance work |
| GST | 15% | Goods and Services Tax on the total |
The “visible” cost — tiles, fittings, cabinetry — is rarely more than 25% of the total. Most of the budget goes to work that has to happen behind the walls and under the floor to deliver a renovation that lasts 20+ years.
Save real money without cutting corners
The decisions that protect your budget on an Auckland renovation:
- Keep the layout. Moving walls, drains, or stacks triggers cascading work. Unless the existing layout is genuinely poor, keeping it can save 10 – 20% on the project.
- Choose mid-range finishes strategically. Spec to the value of the home — a $90K kitchen in a $900K house won’t recoup its cost. A $50K kitchen in the same home delivers similar daily liveability and far better ROI.
- Bundle work together. Combining kitchen + bathrooms + extension into one project is 15 – 25% cheaper than doing each separately — shared mobilisation, single consent, one project management overhead.
- Get a fixed-price contract. After design and consent are complete, lock in a fixed price. Avoid charge-up or cost-plus arrangements where the price floats with the build.
- Hold a real contingency. Budget 15 – 20% on top of the contract price for genuinely unforeseen items. Better to release contingency at the end than scramble for funds mid-build.
- Resist scope creep. Every “while we’re at it” decision adds at least the trade rate plus markup. Decide the scope, lock it in, accept the next renovation will handle the things you didn’t include this time.
- Use design-and-build. A single team handling design and construction delivers the design to the budget — not a design that the budget can’t afford.
When you should NOT renovate
Renovating isn’t always the right call. The honest signals that suggest selling, buying, or rebuilding instead:
- The neighbourhood doesn’t fit your life anymore. A great renovation in the wrong suburb won’t fix that — selling and buying often delivers better life outcomes despite higher transaction costs.
- The layout is fundamentally broken. Some houses can’t be unbroken — load-bearing walls in all the wrong places, ceilings too low, foundations failing. A rebuild often delivers a better outcome than throwing renovation budget at a compromise.
- The house is genuinely past its useful life. Structurally compromised, leaky beyond repair, or so out of date that the renovation cost would exceed the rebuild cost.
- You can’t afford the realistic budget. Trying to do a $400K renovation on a $200K budget is how projects end half-finished. Wait until you have the full budget plus 20% contingency.
Auckland renovation cost FAQs
The questions clients ask most when first looking at a renovation budget.
What’s the average cost of a renovation in Auckland in 2026?
The realistic per-square-metre rate for quality residential renovation work sits at $3,500 – $7,500/m² depending on scope, spec level, and structural complexity. For a typical 150 – 200m² Auckland home, a mid-range renovation runs $400K – $700K, while a high-end full renovation pushes $700K – $1.2M+.
What’s the cheapest renovation that still adds value?
A standard bathroom renovation ($25K – $35K) and a kitchen refresh ($30K – $50K) consistently deliver the highest ROI per dollar spent. Both typically recover 70 – 100% of their cost in property value uplift, with school-zone Auckland suburbs seeing the best uplift.
How much should I budget for contingency?
Plan for 15 – 20% contingency on top of the contract price. Older Auckland homes (pre-1990) lean to the higher end because of hidden issues like asbestos, borer-damaged framing, galvanised plumbing, and rotted subfloors. Newer homes typically need 10 – 15%.
Do all Auckland renovations need building consent?
No. Schedule 1 of the Building Act 2004 exempts cosmetic work (paint, flooring, like-for-like kitchen and bathroom replacement), some minor structures, and the new 70m² granny flat exemption. Anything involving structural changes, plumbing relocation, weathertightness, electrical alterations, or change of building use does need consent.
How does suburb affect renovation cost?
Three ways: site access (narrow inner-city streets add 10 – 15% labour cost), heritage overlays (Devonport, Mt Eden, Parnell, Ponsonby add $10K – $30K in design and consent), and the spec expectation of the local market. The same project description can vary by 20 – 30% across Auckland suburbs.
Is design-and-build cheaper than hiring an architect first?
Usually yes — design-and-build typically costs 5 – 10% less because the design is built to a known construction budget from day one. Architect-and-tender model frequently triggers design revisions when build quotes come back over budget, wasting design fees and adding 8 – 12 weeks to the project.
What’s the ROI on an Auckland renovation?
A well-executed renovation typically recovers 70 – 100% of its cost in property value uplift, with the best returns from mid-range renovations in school-zone Auckland suburbs (Grammar, Epsom, Remuera, Mt Eden). Over-speccing for the suburb delivers diminishing returns.
How long does a typical Auckland renovation take?
From kick-off to handover: 6 – 12 weeks for a bathroom; 8 – 16 weeks for a kitchen; 6 – 12 months for a home extension; 8 – 14 months for a full-home renovation; 3 – 10 months for a recladding project. Design and consent phase is usually as long as construction.
What hidden costs catch most renovations off-guard?
Building consent fees ($2,500 – $15,000), engineer’s design fees ($3,000 – $25,000), council development contributions ($10K – $30K), asbestos testing and removal in pre-2000 homes ($2K – $20K), temporary accommodation, and weather contingency for winter builds.
Should I use a fixed-price contract or charge-up?
Fixed-price almost always — once design and consent are complete and the scope is clear. Fixed-price protects you from cost overruns and forces the builder to manage efficiency tightly. Charge-up can work for genuinely unknown-scope work (character villa restoration) but requires a builder you trust completely.
