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
$17K – $59KLike-for-like refresh from about $17K. Standard family bathroom $31K – $37K including GST. Premium bathroom tiled floor to ceiling: $40K – $59K. Master bathroom or two bathrooms: $36K – $59K; a layout change or consent adds to this. Whether a tiled shower needs building consent depends on the work: replacing one in the same place can be exempt, while a new shower, moved drainage or floor changes need consent, and every tiled shower must still meet Building Code clause E3. If consent applies, allow drawings at around 10% of the build plus about $3,500 – $4,500 in fees. Older Auckland homes carry hidden costs for asbestos, rot, and galvanised plumbing.

$22K – $100KCompact kitchen with a budget finish: $22K – $32K. Most standard family kitchens: $35K – $80K including GST. Large open-plan kitchen with a premium finish: up to $100K. Wall removal adds $20K – $80K but delivers the highest ROI.

Extensions in Auckland in 2026 start from about $4,600/m² including GST for one level, about $7,200/m² for a second storey and about $9,000/m² for a premium finish. The biggest cost drivers: ground-floor vs second-storey, site access, and whether recladding gets triggered.
Home Extension
$69K – $580K+A 15m² bedroom add-on: about $69K. A 34m² living and dining room: about $156K, or about $238K with a new kitchen and bathroom. A 60m² second-storey extension: from about $430K. Design and council fees are extra. Site access difficulty in inner-city suburbs adds 10 – 15% to labour costs.
Read the extension cost guideSecond-Storey Addition
$360K – $580K+A typical 50 – 80m² upper floor from about $7,200 per m² including GST, 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
$204K – $323KA 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
$200K – $550KStandalone 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
$166K – $466KFull reclad of a single-storey 2 – 3 bedroom home in weatherboard: from about $166K including GST. Two-storey 3 – 4 bedroom home: $275K – $358K. Widespread decay confirmed by a damage report can push the total to about $578K. Every figure includes new double-glazed joinery, scaffolding with shrink wrap and building consent. University of Auckland research: weatherboard-reclad homes recover full market value; monolithic-reclad still attracts a 6% discount.
Read the recladding guideFull-Home Renovation
$140K – $780KA typical 3 – 4 bedroom home (about 130 – 180m²) runs $190K – $520K, or $250K – $360K at a standard finish. Larger homes (200m²+) at premium finish run $520K – $780K. Add an extension or reclad and the total can push to $2.5M+ on character properties in premium suburbs.

$49K – $110KConverting an Auckland garage to a living room, home office, sleepout, or self-contained unit. Single garage to a room: about $60K ($49K – $73K); double garage about $90K ($74K – $110K). 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 are where the contingency (about 10% of the build cost) usually gets used, 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 about 10% of the build cost for genuinely unforeseen items, kept outside the fixed contract price and spent only on approved variations at actual cost. 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 a contingency of about 10%.

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?
Whole-home renovation runs about $1,500 – $3,000/m² including GST (around $2,000/m² at standard finish), before extra scope, depending on spec level and structural complexity. Extensions start from about $4,600/m² for one level. For a typical 3 – 4 bedroom Auckland home (about 130 – 180m²), a standard-finish renovation runs $250K – $360K, while a premium full renovation runs $360K – $520K.
What’s the cheapest renovation that still adds value?
A standard bathroom renovation ($31K – $37K) and a budget-finish kitchen (from about $22K for a compact kitchen, $35K – $45K for a standard family kitchen), all including GST, 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?
Allow about 10% of the build cost as a contingency, kept outside the fixed contract price; we show it as an exclusion with a dollar figure and it is only spent on approved variations at actual cost. Older Auckland homes (pre-1990) are where it usually gets used, because of hidden issues like asbestos, borer-damaged framing, galvanised plumbing, and rotted subfloors. Newer homes often use less of it.
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.
