Quick answer: building a new garage in Auckland costs from around $1,800 per square metre for a basic build to about $2,300 per square metre for a high-end one. That puts a single garage from roughly $55,000 and a double from around $90,000, once you allow for the roof and cladding you choose. Size, build grade, roofing and cladding are the four things that move the number.

A garage is a proper consented build, not a kitset drop, so how much it costs to build a garage in New Zealand usually sits higher than people expect. Here’s the breakdown, and a quick way to price yours.

How much does it cost to build a garage in NZ?

We price a new garage on floor area multiplied by a build grade, then adjust for the roofing and cladding you choose. These are the indicative Auckland figures behind our calculator:

These are indicative figures for planning, not a fixed quote. Your final cost depends on the size, the grade of finish, the roof and cladding materials, your site, and whether you need services like power or plumbing run to it.

Single vs double garage cost

Size is the first lever. A single garage of around 30 square metres at the basic grade works out near $55,000 to $65,000 once roofing and cladding are added. A double garage of around 46 square metres runs closer to $90,000 to $110,000 at a mid-range grade.

Step up to a high-end finish, add a mezzanine or a sleepout fit-out, and it climbs from there. Choose your size, grade, roof and cladding in the new garage cost calculator and it builds the estimate for you, rather than you guessing off a per-metre rate. Our new garage cost guide has more on the options.

What size is a single or double garage in NZ?

Size drives the cost, so it pays to know the numbers before you plan. A tight single garage is about 18m², but most people build closer to 20-30m² to fit storage, a workbench or a bit of room around the car. A double garage starts around 36m² and runs up to about 46m² once you allow space to open both doors and move.

• Single garage. Around 3.0-3.6m wide by 6m deep. Fits one car; go wider if you want storage down one side.
• Double garage. Around 5.4-6m wide by 6m deep. Fits two cars, or one car plus a workshop or gym zone.
• Oversized or high-stud. Extra width, depth or height for a boat, a trailer or a mezzanine adds floor area, and cost.

Standard garage sizes in NZ, in metres

There is no single legislated garage size in New Zealand. What exists is a set of dimensions the trade builds to, driven by car sizes, door widths and how much room you need to actually open a door once you have parked. These are the footprints we work from:

The two dimensions people regret are width and stud height. Width, because a 3.0m single leaves you edging out of the driver’s door against the wall. Stud height, because a standard door opening will not clear a roof box, a hoist or a mezzanine, and raising the stud later means new framing and a new door. Both are cheap to add at design stage and expensive to add afterwards.

Our calculator uses generous footprints – a 30m² single and a 46m² double – so the estimate reflects a garage you can actually use, not just park in. Set your own dimensions in the new garage cost calculator to see how size moves the number.

How build grade, roof and cladding change the price

Two same-sized garages can differ by tens of thousands depending on the specification.

• Build grade – basic, mid-range or high-end sets the base rate, covering the quality of the structure, doors, and finishing.
• Roofing – a standard metal roof is the baseline; membrane, concrete tile, slate or copper each add to the total, with slate and copper the priciest.
• Cladding – the exterior finish, from vinyl and steel through to timber, shifts the cost to match or complement your house.

Matching the garage to your existing home is worth doing, both for looks and for resale. The calculator lets you test each combination on the price before you commit.

Kitset vs a built-on-site garage

This is where a lot of the price confusion comes from. A kitset garage has a lower sticker price, but the sticker is not the finished cost. To make a kitset a permanent, compliant structure you still add a consented concrete foundation, drainage, a vehicle crossing where one is needed, and installation. Once those are in, the gap to a built-on-site garage narrows.

What the difference buys you:

• It matches the house. A built garage is designed around your home and site – roofline, cladding and finish – rather than sitting apart as a shed.
• Compliance is handled. Consent, foundation and sign-off are managed as one job, not bolted on afterwards.
• Resale. A garage that reads as part of the home usually adds more value than a standalone kit.

What garage kit prices actually include

Kit prices are quoted for the kit. Read one carefully and it is usually the frame, the roofing, the cladding and the door, delivered flat-packed to the kerb. What sits outside that number is the part that costs real money:

• The slab. A compliant reinforced concrete foundation, engineered for your ground conditions. On a sloping or filled Auckland section this alone can move by tens of thousands.
• Site works and drainage. Cut and fill, stormwater, and connecting it so water goes where the council says it goes.
• Consent. Drawings, the application, council fees and inspections.
• Vehicle crossing. If the garage needs a new or widened crossing from the road, that is a separate council approval and a separate cost.
• Erection labour. Unless you are building it yourself, someone has to put it up and sign it off.

So the honest comparison is not “kit price versus build price”. It is kit price plus everything above, versus build price. Run that comparison and the gap is usually far smaller than the advertised numbers suggest.

If budget is the priority a kitset can still make sense – just price it with the foundation, consent and install included, not the kit on its own.

Building a New Garage vs Converting the One You Have

Plenty of the people who land on a new-garage number are really weighing two options against each other: build a garage, or convert the existing one into a room and live with street parking. They are different jobs with different economics.

Converting is cheaper per square metre, because the expensive bones already exist. The slab, the frame and the roof are there. A conversion is insulation, lining, flooring, glazing, heating and often a bathroom, inside a shell you already own. Our live FAQ puts an Auckland garage conversion from around $40,000, against the $55,000 to $110,000 band for building a new garage from nothing.

What a conversion does not do is give you back the parking. That is the trade nobody costs properly at the start, and on a Millwater or Flat Bush section with a single crossing it matters more than the money. It is also why a common Auckland sequence is both: convert the attached garage into a bedroom, a home office or a granny flat, then build a detached garage at the back for the cars.

If the conversion route is the one you are weighing, our garage conversion cost guide covers the cost drivers, and converting a garage to a granny flat covers what changes when the room has to be self-contained. Either way it is the same crew: the Auckland team that both builds garages and turns them into habitable rooms.

Do you need consent to build a garage?

Almost always, yes. A new garage is a building over 10 square metres, so it needs an Auckland Council building consent, a compliant foundation, and sign-off. There are narrow exemptions for very small, single-storey detached buildings, but a standard single or double garage sits well over the threshold. Confirm your situation with Auckland Council, and the Building Performance (MBIE) guidance sets out what counts as building work needing consent – we manage the consent as part of the build.

Setbacks, vehicle crossings and the site rules that catch people out

Building consent is only half of it. Where the garage can physically sit is set by your zone under the Auckland Unitary Plan, and that is where most garage plans get redrawn:

• Yard setbacks. How close the structure can sit to a side or rear boundary, which varies by zone and can be tighter again under a special character or heritage overlay.
• Building coverage and impervious area. A garage adds roof and hardstand. On a small section you can hit the impervious-surface limit before you hit the coverage limit, which pulls stormwater design into the job.
• Vehicle crossing. A new or widened crossing needs council approval separately from the building consent, and there are rules about how close it can sit to an intersection or a street tree.
• Covenants and cross-lease titles. Neither shows up in a building consent check. A cross-lease in particular can require the other owners’ consent before you add a structure.

None of that is a reason not to build. It is a reason to check the site before you fall in love with a layout. We pull the property file and confirm the zone rules at feasibility stage, and where the answer needs a formal position it goes to Auckland Council or to a Licensed Building Practitioner rather than being guessed at.

Get your garage number, then get it confirmed

A well-built garage adds storage, security and value, and pairs well with wider outdoor work like driveways and landscaping. The smart first move is a realistic figure for the garage you actually want.

Quick answer: Renovation aftercare is the maintenance, paperwork and follow-up that protect your renovation once the tradies leave. Your builder must hand over warranties, insurance and maintenance information, you get a 12-month defect repair period, and the Building Code assumes you keep up normal maintenance from day one.

The build is finished. The scaffolding is gone, the last coat of paint has cured, and for the first time in months your house is quiet. Most Auckland homeowners treat that moment as the finish line. It isn’t. It’s the start of the part nobody briefs you on: the first twelve months, when your rights are strongest, your paperwork is worth the most, and the habits you form decide whether the renovation still looks new in five years.

This guide covers what happens after handover: the documents you are legally entitled to, how the defect repair period actually works, and the maintenance the Building Code quietly assumes you are doing. Some of it is legal. Most of it takes ten minutes a month.

What Your Builder Must Hand Over When The Work Finishes

There is a legal floor here, and it is lower-profile than it should be. Under New Zealand’s residential building consumer protection rules, a contractor must give you three things once the work is complete, no matter what the job cost. Not on request. Automatically.

The three documents you are entitled to

According to Building Performance (MBIE), on completion your contractor must provide:

1. A copy of any current insurance policy held for the building work carried out under the contract.
2. A copy of any guarantees or warranties for the materials or services used, including how to make a claim, whether the guarantee is transferable, and whether it has to be signed and returned to the issuer.
3. Information about the processes and materials used to maintain the work, which MBIE notes matters most “if maintenance is required to meet the requirements of the Building Code or could affect any guarantee or warranty”.

Neglecting to provide that information can mean a fine of $2,000. That third item is the one homeowners skim and later regret, because a warranty you void by cleaning something the wrong way is a warranty you no longer have.

💡 Quick tip: Check every warranty for the words “must be signed and returned”. Some product guarantees only activate once the registration card or online form is completed, and the window is often 30 days from installation.

What a Superior Renovations handover looks like

Our version of this sits at the end of our eight-stage renovation process. When the work is done and the site is cleaned, your project manager runs the final check, then walks the finished spaces with you and your family. Anything you are not happy with gets fixed before sign-off, which is the entire point of walking it together rather than emailing a completion notice.

You then receive the handover pack: workmanship warranty, product guarantees, and the compliance certificates your project required, including waterproofing (PS3), electrical and gas fitting where applicable. About a month after completion we call you, not to sell you anything, but to check how the spaces are working now you are living in them. You keep your project manager’s number.

That single point of contact is deliberate. We split project management out of sales into its own department years ago, so the person who owned your build is still the person who picks up when a soft-close hinge needs adjusting in month seven.

“The walkthrough is the only time everyone is standing in the room together with fresh eyes. Open every drawer, run every tap, look along the skirtings at eye level and then at floor level. Things you notice on that day get fixed on the spot. Things you notice in six months turn into an email chain.”
— Dorothy Li, Design Manager, Superior Renovations

The 12-Month Defect Repair Period, And How To Use It Properly

You have an automatic 12-month defect repair period from the date the building work is complete, and it applies to all residential building work regardless of the price. Inside that year, if you tell your contractor in writing about defective work, they must put it right within a reasonable timeframe. If there is a dispute, the burden sits with them to prove the defect was not their fault, their subcontractor’s, or their product’s.

Put it in writing, every timeA text message counts. A phone call does not. The protection is written into the process, so a verbal mention during a chat is exactly the kind of thing that gets remembered differently a year later. Send the note, keep the sent copy, add a photo.

Timing matters too. The clock starts when all the physical building work you agreed to has been finished. If you have a small item outstanding at handover, ask when the completion date is being recorded, and get that in writing as well.

💡 Quick tip: Set one calendar reminder for month ten. Walk the whole renovation with a torch and a notepad the way you did at handover. You will find the hairline gaps and sticking doors that appeared over a full cycle of Auckland seasons, while you still have two months of the strongest protection left.

What changes after the first year

The protection does not vanish at twelve months. Implied warranties under the Building Act apply for up to 10 years, whether or not they appear in your contract. What changes is who has to prove what: once the repair period lapses, the homeowner has to establish that a defect exists before the contractor is required to fix it.

That is the practical reason the first year is worth using properly. It is also the reason to keep every photo, every invoice and every certificate somewhere you can find them in year eight.

Important note: This is general information about your consumer rights, not legal advice. If a defect turns into a genuine dispute, talk to a property lawyer, and refer any question about consent, code compliance or restricted building work to Auckland Council or a Licensed Building Practitioner.

The Maintenance The Building Code Assumes You Are Doing

Here is the part almost no renovation content covers, and it changes how you read every warranty you were just handed. Building Code clause B2 sets minimum durability periods of 5, 15 or 50 years that building elements must meet “with only normal maintenance”. Those numbers are not a promise the building makes to you. They are a promise made on the assumption that normal maintenance happens.

Maintenance is written into the compliance path

It goes further than B2. As Level, BRANZ’s sustainable building resource, sets out, the Acceptable Solution E2/AS1 states that “maintenance shall be carried out as necessary to achieve the required durability of materials, components and junctions”, and describes specific requirements such as washing exterior surfaces, maintaining finish coatings and keeping minimum clearances clear.

Wall claddings and coating systems are the ones most likely to need regular attention to stay waterproof and durable. Some cladding systems also have working parts, like cavity drainage outlets, that only keep functioning if they are kept clear.

Neglect can cost you the redress, not just the finish

MBIE is direct about the consequence in its guidance on protecting your investment: all buildings need ongoing maintenance and it is the owner’s responsibility to see that it happens in a timely way, partly to keep warranties and guarantees valid. If a problem traces back to maintenance that was skipped or done badly, a claim for defective workmanship gets a lot harder.

National data suggests plenty of room to improve. The BRANZ House Condition Survey found that among owner-occupied homes, just under half were well maintained, with the rest split between reasonably and poorly maintained.

💡 Quick tip: Ask your builder which items in your renovation carry a 5-year durability rating rather than 15 or 50. Sealants, coatings and moving hardware usually sit at the short end, and those are the ones that reward a yearly look.

Kitchen Aftercare: Benchtops, Cabinetry And The Things That Move

A kitchen takes more physical abuse than any other room in the house. Heat, steam, knives, spills and a few thousand door closes a year. The good news is that almost everything that ruins a new kitchen early is a cleaning product or a habit, not a fault.

Benchtops, doors and cabinet interiors

Melamine and laminate surfaces want warm water and a little detergent, and that is genuinely it for day-to-day cleaning. Laminex New Zealand’s care guide for Melteca notes that textured finishes sometimes need a soft brush to lift dirt build-up and the residue left by spray-on cleaners, and it names diluted Janola or Handy Andy for stubborn marks. Abrasive pads and scouring powders are what put permanent dull patches into a finish that was fine the day before.

Stone and engineered stone benchtops have their own rules and they vary by manufacturer, which is exactly why the product guarantees in your handover pack are worth ten minutes of reading. The pattern we see most often is a homeowner reaching for the strongest cleaner in the cupboard on a stain that would have lifted with soapy water and patience.

Hardware, hinges and the things that move

Soft-close hinges and drawer runners are adjustable. They are meant to be. A door that has dropped a couple of millimetres or a drawer that no longer closes flush is a two-minute adjustment, not a defect you have to live with, and it is a standard aftercare call in the first year.

The other habit worth forming is running the rangehood on low for a few minutes after cooking rather than switching it off with the element. Steam and cooking grease that stay in the room settle on cabinetry, and grease is the thing that makes a finish look tired long before it wears out. If you are still at the planning stage, this is the sort of detail our team works through when we specify cabinetry and benchtops for Auckland kitchens.

💡 Quick tip: Keep one microfibre cloth for the kitchen only and wash it weekly. Most “the finish has gone patchy” calls trace back to a cloth carrying grit or old cleaner residue around the room.

Bathroom Aftercare: Silicone, Grout And Getting The Moisture Out

Bathrooms are where Auckland’s climate does its quiet work. Warm, humid air, long showers, and in winter a room that never quite dries out between uses. Nearly all bathroom aftercare comes down to one idea: get the water off the surfaces and the moisture out of the room.

Silicone, grout and the junctions that do the work

The waterproofing under your tiles is a system, and the visible sealant lines at the wall-to-floor and wall-to-bath junctions are part of how it keeps performing. Silicone is a maintenance item with a finite life, not a permanent fixture. Watch for it lifting at the corners, going soft, or discolouring in a way that does not clean up, and replace it before water gets a route in behind.

Grout behaves differently depending on what was specified. Cement-based grout is porous and benefits from sealing and gentle cleaners, while epoxy is denser and far less absorbent, at a higher cost. We compare the two in detail in our guide to epoxy grout versus cement grout, and the choice you made during the build determines the routine you need now.

“People clean bathroom tiles beautifully and never touch the silicone. It’s the silicone that tells you what’s happening. If a line has gone soft or is pulling away in the corner, that’s the bathroom asking for ten minutes of attention before it becomes a bigger job.”
— Cici Zuo, Head of Sales, Superior Renovations

Ventilation is aftercare, not just design

A well-specified extract fan only helps if it runs long enough. Leaving the fan going for fifteen to twenty minutes after a shower, with the door shut, clears far more moisture than switching it off as you leave, and it protects paint, joinery and grout at the same time. Squeegeeing the shower glass takes fifteen seconds and saves a weekly scrub, particularly in hard-water pockets.

If mould keeps returning despite all of that, the problem is usually the system rather than your cleaning. Our guide to bathroom ventilation in New Zealand covers ducting, fan sizing and where the moist air actually ends up. Knowing how a bathroom gets waterproofed and sealed before the tiles go on helps too, because that hidden layer is what your surface maintenance is protecting.

💡 Quick tip: MBIE’s maintenance guidance recommends keeping living spaces heated to at least 16°C as part of moisture control. In a Titirangi bush setting or a shaded Grey Lynn villa, that single habit does more for mould than any cleaning product.

The Outside Of The House, And What Auckland’s Climate Does To It

If your renovation touched the exterior (cladding, joinery, decking or a new roof), this is where maintenance moves from cosmetic to structural. Auckland gives you humidity, salt-laden air along the coast, and long damp winters. Washing is not a cosmetic job here; on most cladding systems it is a condition of the warranty.

Washing, and how often

Level’s maintenance guidance gives the kind of frequencies a maintenance schedule should contain: washing down painted weatherboard cladding at least six-monthly, and repainting every 8 to 10 years. Fibre-cement claddings should be washed at the interval the manufacturer specifies, using a soft brush and a low-pressure hose rather than a waterblaster.

See the full project →

Coastal suburbs are the ones to watch. Homes in Devonport, Herne Bay, Takapuna and along the eastern bays collect airborne salt on joinery, hardware and fixings, and a rinse with fresh water is the cheapest maintenance job in the country. Inland, the bigger issue is shade and moss, which is why Titirangi and the bush-edge suburbs need their roofs and gutters watched more closely than a sunny Flat Bush section.

The annual walk

MBIE’s guidance is refreshingly simple on frequency: inspect the roof annually, inspect cladding at least annually with extra attention on homes built from the 1990s onwards, and clear gutters and spouting at least once a year. Check window and door seals while you are there, along with flashings and any minimum ground clearances that garden beds or new paving may have quietly buried.

That last one catches people after landscaping. A raised garden bed or a new path against the wall can bridge the clearance the cladding relies on, and it is a common cause of trouble in homes that were otherwise well built. The same logic applies across the way we scope, build and hand back a full home renovation: the details that protect the house are the ones you cannot see once the job is finished.

Underfloor Heating – Epsom- Auckland

💡 Quick tip: Do the gutter clean in late autumn, after the leaf drop and before the winter rain properly arrives. In Auckland that usually means May, and it is the single highest-value hour you will spend on the house all year.

Build Yourself A Maintenance Schedule And Keep The Paperwork

All of this works better written down. A maintenance schedule is simply a document listing the materials and building elements in your home and the maintenance each one needs, with frequencies attached. Level makes the case that it helps owners know what to do, records what a material actually was years after the build, and reduces a builder’s exposure when a problem is caused by maintenance that never happened.

Where to start

BRANZ publishes free homeowner maintenance guides covering roofs, subfloors, interiors, exteriors and building services at maintainingmyhome.org.nz. Start there, then add the specifics from your own handover pack, because a generic schedule cannot know that your splashback is a particular product with a particular cleaner it dislikes.

Keep the file where you will find it

Scan the whole handover pack the week you receive it and store it in the cloud alongside the consent documents and code compliance certificate. Photograph the finished rooms while they are empty and clean. If you sell in seven years, that folder is a genuine asset, and if something goes wrong in year eight it is the difference between a conversation and an argument.

💡 Quick tip: Add three recurring calendar events the week you move back in: gutters in May, exterior wash twice a year, and a full walkthrough at month ten. Three reminders cover most of what a maintenance schedule asks of an average Auckland home.

Renovation Aftercare: The First Year Is Yours To Use

Renovation aftercare is not a chore list bolted onto the end of a project. It is the last stage of the build, and it is the one you control. The paperwork you file, the notes you send in writing, and the ten-minute habits you form in the first few months decide whether your renovation is still performing in a decade or whether you are having a conversation about who pays.

Read the pack. Diarise the walkthrough. Wash the outside. And if something is not right, say so in writing while the clock is still in your favour.

Garage Conversion Cost NZ: Bedrooms, Bathrooms and Double Garages

Quick answer: A garage conversion in Auckland starts from around $40,000 for a dry room such as a bedroom, office or gym. Adding a bathroom takes it to $80,000–$110,000, a self-contained single-garage unit runs $110,000–$145,000, and a double garage turned into a two-bedroom unit lands at $160,000–$220,000, build cost only.

You’re staring at the garage. The car’s parked on the drive most weeks anyway. What if that space became a teenager’s bedroom, a home office, a rental income stream, or somewhere for your mum to live closer without moving in?

The first question is always the same: what’s it actually going to cost? You’ve probably already pulled up a few ranges online, and they run from about $30,000 to well past $200,000. Useful as a wall poster. Useless for planning. Once you’ve got a budget in mind, see how we turn an Auckland garage into a consented, habitable room, from the first drawing to the final inspection.

What you need is a number that fits your garage. Your section. Your conversion type.

That’s what this calculator gives you.

How Much Does a Garage Conversion Cost in NZ?

The type of room you’re creating sets the price far more than the size of the garage does. These are the bands Superior Renovations publishes for Auckland: the starting point on our renovation FAQ, and the project bands in our garage to granny flat cost and consent guide.

Those are build costs, and they leave three things out. Design and consent typically add $10,000–$20,000. A self-contained unit with its own kitchen can trigger Auckland Council Development Contributions of $5,000–$20,000 depending on the zone. And foundation remediation or a drainage pump system sits outside the bands too, which is why we tell people to hold a 10–15% contingency on top of any quoted figure.

Notice the two-bedroom row needs 50–60m². A standard double garage is 36–40m², so measure yours before you plan for two bedrooms.

Why a Calculator Beats a Generic “Per m²” Estimate

On our own published bands, an Auckland garage conversion runs from around $40,000 for a bedroom to $220,000 for a two-bedroom unit. That’s accurate. It’s also useless for budget planning.

The range is that wide because “garage conversion” covers wildly different projects. Converting a single garage into a teenager’s bedroom on a flat section in Albany sits at the bottom. Turning a double garage into a self-contained granny flat with kitchen, bathroom, and separate entry on a leaky-era home in Glen Eden sits near the top. Both are “garage conversions in Auckland.” Both sit inside that spread. They cost vastly different amounts.

The headline range alone doesn’t tell you which one you are.

That’s where the calculator earns its keep. Instead of giving you a number that covers everyone, it asks the specific questions that move your number, type of room, size of garage, whether you need plumbing, the condition of what’s already there, and narrows the range to the kind of project you’re actually planning.

It takes a few minutes, and what it gives you isn’t a quote. More on that below.

What Goes Into the Estimate

The calculator works through the same variables we look at when we price a real project. Each one is a genuine cost driver, and below is roughly what each does to the number.

Type of conversion. This is the single biggest driver. A dry-room conversion (bedroom, study, gym) starts from around $40,000. Add a bathroom and you’re at $80,000–$110,000. A self-contained unit with kitchen, bathroom and separate entry runs $110,000–$145,000 in a single garage, and $160,000–$220,000 as a two-bedroom unit. The jump isn’t linear: wet areas need plumbing, drainage connections, waterproofing, ventilation and higher-spec fixtures.

Size of the garage. Single garages typically run 18–22m². Double garages 36–40m². A double conversion costs more in absolute terms but the per-m² rate often comes down because fixed costs (consent fees, design, structural assessment) spread across more floor area.

Foundation and floor condition. Most garage slabs were never designed for habitable use: often no damp-proof membrane and no insulation underneath. Bringing the floor up to habitable standard means either insulating over the existing slab (you lose ceiling height) or breaking out and re-pouring, which we’d budget at roughly $8,000–$15,000 as an indicative planning figure. A slab that sits below the surrounding ground is harder again, because getting drainage to work around it gets complicated quickly.

Insulation and weathertightness. Turning a garage into habitable space brings the H1 energy-efficiency clause into play, so walls, ceiling and floor all have to hit current R-values. The current documents (H1/AS1 and H1/VM1, 6th edition) took effect on 27 November 2025, and the previous 2022 editions stay valid only for consents lodged up to 26 November 2026 — worth asking which edition your design is being drawn to. Most garages were never lined or insulated in the first place, so plan on insulating the lot. Our guide to insulating an NZ home covers the products and where each one goes.

Plumbing and electrical. Running new water, waste and drainage to a detached garage costs more than to an attached one. On a self-contained unit, the longer runs and separate connections can add $10,000–$25,000 over the same conversion on an attached garage, and a low-lying site that can’t get fall to the sewer may need a pump system as well, at $4,000–$8,000 plus ongoing maintenance. Electrical needs to be brought up to current Standards and usually means a new sub-board.

Finish level. Standard GIB and vinyl, or feature timber lining and engineered flooring? On a 30m² self-contained conversion, interior finishes (flooring, painting, ceiling, joinery) typically run $12,000–$18,000 at a standard spec. Feature linings and premium flooring push that line up fast.

What the Calculator Gives You, and What It Can’t

The calculator asks a short set of questions about your project, then where to send your result. Treat what comes back as a planning range, not a price.

It’s not a quote. Quotes need site visits, drawings, and detailed scope. The estimate is the layer before that: the number that tells you whether your project sits in a budget you can work with, or whether you need to rescope before going further.

Check what any number leaves out. The bands on this page are build costs. Design and consent fees, Development Contributions on a self-contained unit, resource consent if your plans breach a zone rule, and anything hiding under the slab or behind the existing lining all sit outside them. We’d rather flag the limits than pretend they don’t exist.

If the number looks workable, the next step is usually a feasibility consultation, where we walk through your specific garage, what you’re trying to achieve, and what’s realistic on your section. The consent drawings come from Sonder Architecture, our architectural division, so the people drawing your garage work alongside the team that builds it. That conversation comes after you’ve seen the estimate, not before.

Single, Double or Detached: What Your Garage Type Changes

Two things about your garage set the shape of the whole project before anyone talks about finishes: how big it is, and whether it is attached to the house.

Single Garage Conversions (roughly 18–22m²)

A single garage gives you one good room. A bedroom, a home office, a gym, a studio. It is the cheapest conversion available and it sits at the bottom of the $40,000–$60,000 dry-room band, but the per-square-metre rate is the highest of any conversion type, because the consent, design and structural assessment cost the same whether you are converting 20m² or 40m².

If you want a bathroom in a single garage, be realistic about what is left. Take out 3–4m² for a compact bathroom and the habitable room that remains is small. That is usually the point at which people either accept a dry room or start looking at the double.

Double Garage Conversions (roughly 36–40m²)

This is the footprint that makes a genuinely self-contained unit work: open-plan living, a bedroom, a bathroom and a kitchenette without any of it feeling like a corridor. It also spreads the fixed costs across twice the floor area, so the per-m² rate drops even though the total goes up. Two bedrooms is the stretch: our published band for a two-bedroom unit is $160,000–$220,000 at 50–60m², which is more floor area than a standard double, so a disciplined layout and smaller rooms are the price of fitting both in.

Attached vs Detached: The Services Question

An attached garage is almost always the cheaper conversion, and the reason is plumbing rather than structure. Water, waste and drainage are already a few metres away, and the wall between garage and house is often already close to a habitable build-up.

Concept plans · three layouts, one shell

Layout is the biggest number the calculator cannot see

Layout is the biggest number the calculator cannot see (Existing)×Existing

Layout is the biggest number the calculator cannot see (Option 1)×Option 1

Layout is the biggest number the calculator cannot see (Option 2)×Option 2

Layout is the biggest number the calculator cannot see (Option 3)×Option 3

Three arrangements of one double garage. The shell costs the same in all three; the plumbing, the number of internal walls and the amount of new glazing do not. Use the calculator for the envelope, then let the layout decide the rest. Concept plans by Sonder Architecture. Concept only, not consent documentation.

A detached garage at the back of the section is a different job. Water, waste and drainage have to be trenched out to it, and on a self-contained unit those longer runs and separate connections can add $10,000–$25,000 over the same conversion on an attached garage, before anything happens inside the building. Power usually means a new sub-board and a run out to the structure. Detached conversions also tend to be the ones that hit boundary, height-to-boundary and impervious-area rules, because they sit near the edge of the section.

Converting a Garage Into a Bedroom

This is the most common brief we get, and it is the cheapest useful thing a garage can become. There is no plumbing, no drainage, no waterproofing, so the whole wet-area cost jump never happens.

What it still needs, and what people underestimate: the slab has to come up to habitable standard, which means either insulating over it and losing ceiling height, or breaking it out and re-pouring (allow roughly $8,000–$15,000 as an indicative figure). The walls, ceiling and floor all have to meet current H1 R-values. The garage door opening usually becomes a window or a wall, and that changes both the structure above it and the look of the street frontage. Ventilation and natural light have to satisfy the Building Code for a habitable room, which a garage was never designed to do.

💡 Quick tip: Check your ceiling height before you fall in love with the idea. Insulating over an existing slab eats 100mm or more, and a garage that started low can end up below the height a habitable room needs. Measure first, design second.

Whether the finished room can be rented, and whether it counts as a separate dwelling for rates and consent purposes, is a question for Auckland Council or a Licensed Building Practitioner rather than a calculator. If you are weighing the conversion against other ways of adding a room, our guides to converting a garage into a granny flat, container homes versus regular granny flats, and the cost of building a new garage cover the alternatives. If losing the garage is the sticking point, our garage build cost guide prices putting a replacement elsewhere on the section.

Converting a Garage Into a Kitchen, Studio, Gym or Living Area

Bedrooms get the most enquiries, but plenty of people want something else from the space. One rule holds across all of them: dry rooms are cheap, wet rooms are not, and a kitchen changes what the building is.

Garage to Home Office, Studio or Gym

Price these like a bedroom. There’s no plumbing, so they sit in the same dry-room band that starts from around $40,000, and the same slab, insulation, light and ventilation work applies once you intend to use the space as a habitable room. A gym is the one to think twice about. Heavy plates on a slab that’s been insulated over need a floor build-up that can take the load, so tell the designer what you’ll be lifting before the floor is specified.

Not every gym or workshop has to become a habitable room. Our granny flat guide treats a space with no plumbing that nobody sleeps or works in full-time as non-habitable, which is a smaller and cheaper job. Whether yours qualifies is a question for Auckland Council or a Licensed Building Practitioner, not a calculator.

Converting a Garage Into a Kitchen

Adding a kitchen is where the project changes category. A garage with its own kitchen and bathroom is a self-contained unit, which runs $110,000–$145,000 in a single garage on our published bands, and in Auckland a second self-contained unit commonly brings resource consent and Development Contributions into play alongside the building consent. If what you actually want is a second cooking space for the main house, such as a scullery or an entertaining kitchen off the living area, say so at the design stage, because how the space is classified changes the consent path. Check your zone with Auckland Council or ask us before you draw it.

Garage to Living Space: Extending the House Into It

An internal or attached garage that opens straight into the house is the easiest conversion to make feel like part of the home. Widen the internal doorway and the garage becomes a family room, rumpus or second lounge, with services close by and no separate entry to build. The wall you open up is the structural question. If it’s load-bearing, get an engineer and an LBP involved before anyone picks up a saw, and expect the beam to be part of the consented work. Attached conversions can also need a fire-rated wall between the new room and the rest of the house, depending on the design.

Half a Garage: Converting One Bay of a Double

Keeping one car bay and converting the other is a popular compromise where the section has nowhere else to park. Just don’t expect half the garage to cost half as much. The design, consent and structural assessment cost much the same whatever the floor area, and you’re adding a new wall between the room and the remaining car bay, built to habitable-room standard on the room side. Per square metre, a half conversion is one of the more expensive ways to add a room, so price the full double before you rule it out.

The Three Variables That Move Your Number the Most

If you’ve used the calculator and want to understand what drove your result, these three factors do most of the heavy lifting.

1. Whether you’re adding plumbing. The single biggest jump in cost is the leap from a dry room to a wet one. On our published bands, adding a bathroom takes a project that starts from around $40,000 to $80,000–$110,000, and adding a kitchen as well takes a single-garage unit to $110,000–$145,000. If the goal is just usable floor space, a dry-room conversion gives you the best return per dollar. If you’re going self-contained, expect the budget to roughly double or more.

2. Condition of the existing structure. Garages weren’t built to habitable standard. A garage with a sound slab, intact roof, good wall framing and services nearby converts faster and cheaper. A tired garage with rotting bottom plates, a cracked slab or old fibre-cement cladding can soak up a big share of the budget before the conversion proper even starts, and anything that might contain asbestos needs testing before anyone cuts into it. Our guide to asbestos testing and removal in an Auckland renovation explains who tests, who pays and what happens next. Get a builder to assess the structure before you commit to a budget.

3. Labour, and how it’s priced. Qualified trades in Auckland charge $120–$150 an hour, the rate Superior Renovations publishes on its FAQ, and a conversion runs a builder, electrician, plumber, gib stopper and often a tiler in sequence. A fixed-price quote can look higher than a charge-up estimate because the builder is carrying the risk of whatever turns up behind the lining. On a charge-up job, that risk sits with you.

Where the money goes on a self-contained conversion. Our granny flat guide breaks a $130,000, 30m² self-contained build down like this: bathroom $22,000–$28,000, kitchenette with appliances $18,000–$28,000, slab works, linings, insulation and weather membrane $25,000–$35,000, plumbing and electrical $15,000–$22,000, glazing and joinery to replace the garage door $12,000–$18,000, and interior finishes $12,000–$18,000.

Knowing which of these three is the biggest factor on your garage tells you where to focus when you’re trying to bring the number down, or where to brace yourself if it has to stay where it is.

Convert the Garage, or Demolish and Build New?

This question matters more in 2026 than it did a year ago.

In January 2026, the Schedule 1A granny flats exemption came into force. According to MBIE’s Building Performance guidance, a small standalone dwelling of up to 70m² can be built without a building consent if it has a simple design and meets the Building Code, the homeowner notifies council before building starts and once it’s complete, the work is carried out or supervised by licensed building professionals, and every exemption condition is met. That’s a structural shift in the economics of adding a second dwelling to your property.

Here’s the awkward bit: the exemption applies to building new, not to converting existing structures. A garage conversion still triggers building consent because it changes the use of an existing building, involves structural alterations, and almost always involves plumbing and electrical work.

Which means homeowners now have a genuine choice:

Convert the existing garage. Cheaper if the garage is in good condition. Faster start. Keeps the existing footprint. Consent required. From around $40,000 to $220,000 depending on scope.

Demolish the garage and build a new exempt dwelling of up to 70m². Higher upfront cost: our published band is $180,000–$260,000 for the build. But no building consent and no consent processing wait, more floor area, and standalone status. You still apply for a project information memorandum (PIM), notify council before and after, and pay any development contributions, and resource consent is a separate question that depends on your zone. The numbers can work out closer than they look once you factor in the consent timeline avoided.

The break-even point depends heavily on the condition of the existing garage. If it’s structurally sound with good services nearby, convert. If it’s rotten, undersized, or full of asbestos, the new-build pathway can be the cleaner answer.

The calculator gives you the conversion estimate. If you want to weigh that against a new-build SSAD option, that’s worth a feasibility conversation before you commit to either path.

Frequently Asked Questions

Please note: Cost factors vary project to project, and the calculator’s accuracy depends on the inputs you provide. The estimate is a planning tool, not a quote. Rates and material costs shift with the market, and final project pricing requires a site visit and detailed scope assessment of the existing garage. While information is considered current at the date of publication, Superior Renovations isn’t liable for any decisions made solely on the calculator output.

Quick answer: a full roof replacement on a standard Auckland home costs $10,000 to $45,000, and most homeowners pay $15,000 to $30,000 for Colorsteel long-run steel at $90 to $180 per square metre installed, including removal of the old roof. Corrugated iron sits lower at $70 to $140 per square metre and concrete tiles higher at $120 to $200. Roof size, pitch and access move the number more than the brand of sheet does.

Roof size is the main driver, so a per-square-metre figure only gets you halfway. Below you’ll find the rate by material, worked totals by roof size, what a quote should and shouldn’t include, how long the job takes, and a fast way to price your own roof.

How much does a new roof cost in NZ?

For a standard Auckland home, a full reroof runs $10,000 to $45,000, and most land between $15,000 and $30,000. The material sets the rate per square metre and the roof sets how many square metres you pay for. These are the installed rates we publish for the three roofs we replace most:

Rates are from our published renovation FAQ. Where a house falls inside each band comes down to the roof’s size, its pitch and how easy it is to get scaffold and a truck to it.

The base rates inside our reroofing calculator

The calculator works from roof area multiplied by a material base rate, then adds for pitch and for stripping the old roof. These are the figures it starts from:

These are indicative figures for planning, not a fixed quote. The steel base rate is before the strip: add the 25% and it lands near the top of the $90 to $180 installed band above, which is where a pitched Auckland roof with scaffold usually sits. The final number depends on your roof’s exact area, its pitch and complexity, the condition of the framing underneath, and the material you choose. If you’re leaning towards steel, our Colorsteel roofing cost guide goes deeper.

Roof replacement cost by roof size in New Zealand

Because the rate is per square metre, the fastest way to sanity-check a quote is to work from your roof area. The figures below are worked straight off the two calculator base rates above, on a normal pitch with the old roof left in place. They are arithmetic, not quotes, and they don’t include scaffolding on a two-storey home or any framing repairs found once the old roof is lifted.

Two things move those numbers fast. A steep or multi-angle roof adds about 10% for the extra time, safety gear and offcuts. And a two-storey home needs scaffold, which is priced on the job rather than per square metre of roof. If your roof is bigger than you think, that’s normal: pitch and eaves overhangs mean roof area routinely runs 20% to 30% above floor area.

The 250m² stripped figure sits just above the $45,000 top of our published range. That’s the honest signal that a large, cut-up roof is where a proper site measure matters most, because small errors in area multiply fast.

What does it cost to reroof a typical home?

Say you’ve got a standard single-storey Auckland home with roughly 150 square metres of roof, going with long-run steel on a normal pitch. That’s about $22,500 for the new roof. If the existing roof needs stripping first, add around 25% and you’re near $28,000. Choose asphalt shingles instead and the base drops to about $15,900.

A steep or cut-up roof with lots of angles pushes it higher again. Enter your roof size, material and pitch into the reroofing cost calculator and it works out your figure in seconds – handy before you start ringing around for quotes.

Metal roof replacement, re-roofing iron and switching from tiles

Most Auckland reroofs are one of three jobs, and each one is priced and consented a little differently.

Replacing corrugated iron with new long-run steel

Old iron to new long-run steel is the most common reroof we price. The sheets come off in sections, the battens or purlins underneath get checked for rot and loose fixings, new underlay goes down, then the new sheets, flashings, ridge and barge capping. Because the new roof is the same kind of product in the same position, it usually sits inside the Building Act’s like-for-like exemption covered further down. The real variables are how much of the timber under the old iron needs replacing, and whether the spouting is worth keeping. If you’re weighing profiles and colours, our guide to what a Colorsteel roof costs goes through the options.

Replacing a tile roof

A tiled roof can be re-laid in new tiles or swapped for steel. Tiles to steel takes weight off the house, but it is not a straight sheet swap. Tile battens are set out for tiles, not for long-run sheets, so the roof usually needs new battens or purlins, and the hips, ridges and valleys are detailed differently. The look of the house changes too, which matters on a character street. Because the new material isn’t comparable to the old one, confirm the consent position with Auckland Council before you commit rather than assuming the like-for-like exemption applies.

Pressed-metal tiles and older cement sheet

Stone-chip pressed-metal tiles from the 1970s and 1980s often reach the point where the chip has gone and the steel underneath is exposed. Replacing them with long-run is a common upgrade. Older cement roofing needs more care: WorkSafe says a home built before 1 January 2000 may contain asbestos, and that asbestos cement was often used in roof sheeting and ridge capping. Test a sample before anyone lifts a sheet. Our asbestos and renovation guide covers what testing and licensed removal involve.

What a new roof price should include (and what sits outside it)

Roofing quotes are notoriously hard to compare because two companies can price very different scopes. Before you weigh one against another, check what each one has actually allowed for.

Normally inside the price:

• Removing and disposing of the old roof, where a strip is part of the job.
• New roofing underlay, flashings, ridge and barge capping.
• Fixings suited to your site, which matters near the coast.
• Access and safety for a single-storey roof, plus site clean-up.

Usually priced separately, or once the roof is off:

• Scaffolding on a two-storey or steep roof.
• Repairs to battens, purlins or framing that only show up on the strip.
• New spouting and downpipes, if the existing ones are past it.
• Skylights, solar brackets, or moving a flue or aerial.
• Asbestos testing and licensed removal on older roofing. WorkSafe notes that asbestos cement was often used in roof sheeting and ridge capping, that homes built before 1 January 2000 may contain asbestos, and that the only way to confirm it is to test a sample. Budget for testing on any roof of that age.

How to compare roofing quotes line by line

Two roofing quotes that are thousands of dollars apart are rarely the same job. Line them up against this list before you decide which one is cheaper:

• Roof area. Is it stated in square metres, and did someone measure it, or was it taken off a floor plan?
• Material, profile and colour. A named product, not “long-run” on its own.
• Underlay and flashings. New, or reusing what’s there?
• Strip and disposal. Included, and priced as its own line.
• Timber repairs. A rate for replacing rotten battens or purlins, so a surprise under the old roof has a known price rather than an open one.
• Scaffold and edge protection. Included, or a separate hire.
• Spouting and downpipes. Replaced, re-used or not mentioned.
• Warranties. The manufacturer’s material warranty and the roofer’s workmanship warranty are two different documents. Ask for both.

Once the job reaches $30,000 including GST, the paperwork stops being optional. Our guide to the $30,000 written-contract rule explains what your builder has to hand over before you sign.

How long does a reroof take, and what happens on site?

A straightforward single-storey reroof is often done in a few days to a week, weather permitting. A two-storey house, a steep roof or a strip that turns up rotten framing adds time. The order of work is much the same on every job:

1. Measure, quote and consent check. The roof is measured, the material chosen, and the consent pathway confirmed before a date is booked.
2. Access. Scaffold or edge protection goes up, especially on a two-storey home.
3. Strip in sections. The old roof comes off a section at a time, so the house is never left open and uncovered overnight.
4. Inspect and repair. Battens, purlins and framing are checked once they’re exposed, and anything rotten is replaced before the new roof goes on.
5. Underlay, sheets and flashings. New underlay, then the roofing, ridge, barge and any penetrations for flues, vents or skylights.
6. Spouting, clean-up and sign-off. New spouting if it’s in the scope, the site cleared, and a final walk-round.

On our jobs one project manager owns the schedule, the materials and the council communication from the strip to sign-off, so you’re not the one chasing the roofer about the weather. A roof that’s open for part of a day also changes your risk while the work is on. Our renovation insurance guide explains what to check with your insurer before work starts.

Long-run steel vs asphalt shingles vs tiles

The two most common reroofing choices in Auckland sit at different price points and suit different homes.

Long-run steel

Long-run steel (including Colorsteel) is the Auckland workhorse – durable, quick to install on straightforward roofs, and well suited to our wind and rain. It’s the higher of the two rates but a long-life option.

Asphalt shingles

Shingles come in lower per square metre and give a different look, often chosen for character homes or steeper roofs where they sit well. They’re a solid mid-range option worth pricing alongside steel.

Concrete and pressed-metal tiles

Plenty of 1970s and 1980s Auckland homes still carry concrete tiles or the pressed-metal, stone-chip tiles of that era. Both can be replaced like for like, and both change the maths if you switch material: going from a light metal roof to heavy concrete tiles adds load the existing framing may not have been designed for, which pulls the job into consent territory. That’s covered below, and it’s worth settling before you fall in love with a different profile.

Signs it’s time to replace the roof rather than repair it

A patch is the right answer more often than roofers admit. These are the ones where a full replacement usually wins:

• You’ve paid for the same leak twice. Repeat repairs in the same area usually mean the substrate or the flashing detail is the problem, not the hole you keep patching.
• Rust at the laps and fixings, not just surface staining. Corrosion working out from the fixing lines is a sheet-life issue.
• Widespread chip loss on pressed-metal tiles, where the bitumen is exposed and going chalky.
• Sagging lines or soft spots underfoot, which point at the framing rather than the cladding.
• Age past the Building Code durability point. Clause B2 of the Building Code requires parts of the building envelope that are moderately difficult to replace, roof cladding among them, to last at least 15 years with only normal maintenance. Well beyond that, a reroof is maintenance catching up rather than an upgrade.
• You’re about to spend money on what’s underneath. New insulation, a new kitchen ceiling or a full interior repaint all argue for sorting the roof first.

Do you need a building consent to replace a roof?

Often not, but it hinges on whether the new roof is comparable to the old one. Schedule 1 of the Building Act exempts replacement of a component with a comparable component in the same position. MBIE’s guidance uses roofing as its worked example: replacing 20-year-old profiled metal roof cladding with comparable profiled metal roofing sits inside the exemption.

Where it tips the other way:

• Changing to a heavier material. MBIE’s counter-example is corrugated iron swapped for concrete tiles, where the added load is likely to affect the building’s structural behaviour. That needs consent.
• Structural work. Substantial replacement of components contributing to structural behaviour or fire safety is outside the exemption.
• A durability or weathertightness failure. The exemption doesn’t cover replacing something that failed to meet the Building Code, including external moisture requirements.

Consenting and Restricted Building Work calls belong with your council or a Licensed Building Practitioner, not a blog. Auckland Council is the consenting authority here, and we confirm the pathway with them as part of the project so you’re not guessing.

Should you reroof, or reroof and reclad together?

If your home is due for both, doing them together can save on scaffolding and disruption, since the same access serves both jobs. It’s common on older homes where the roof and cladding have aged at the same rate. If that’s you, it’s worth reading our Auckland home renovation guide to plan the sequence. Monolithic-clad homes are the obvious case, and our monolithic cladding guide covers how to tell whether the walls need attention at the same time as the roof.

On the cost side, our recladding cost guide sets out what the cladding half runs to, and you can see how we reclad and reroof in the same programme rather than paying for access twice.

What drives your reroofing cost

• Roof area – the biggest factor, and larger than your floor area.
• Material – long-run steel sits above asphalt shingles per square metre.
• Pitch and complexity – steep, multi-angle roofs take longer and cost more.
• Removing the old roof – stripping and disposing of the existing roof adds to the total.
• Access – scaffold on a two-storey home, or a tight site with no truck access.
• Underlying repairs – damaged battens, purlins or framing found during the strip.

A new roof protects everything under it, so it’s worth getting right. Start with the reroofing cost calculator for an instant estimate, see local context in our reroofing costs in Auckland guide, then request a free feasibility report for a measured quote from the Superior Renovations team.
