In 2026, building a new home in Franklin typically costs $3,500 to $4,500+ per square metre for the house itself, including GST. For a standard 150 m² three-bedroom home, that puts the build alone at roughly $525,000 to $675,000 before land, site works, consent and council contributions.
That per square metre figure is a starting point, not a quote. Two similar homes can land very differently depending on:
- The section: a flat, fully serviced site in a Pukekohe subdivision versus a sloping rural block near Waiuku that needs a septic system, water tanks and a long driveway.
- The council: whether your land sits under Auckland Council or Waikato District Council changes consent processes and development contributions.
I’m John from Rag Reno’s. This guide covers where the money actually goes on a Franklin new build, what quotes often leave out, and how to budget so the number you start with is the number you finish with.
💡 Worth knowing: the house rate is only half the budget. The section decides the other half.What does it cost per square metre to build in Franklin in 2026?
Per square metre rates are useful for early planning, but they usually describe the house only. They rarely include earthworks, driveways, services or council fees.
What do the different build levels get you?
| Build level | Typical rate (per m², incl. GST) | What it typically includes |
|---|---|---|
| Entry level | $3,500 to $3,900 | Simple layout, standard cladding, standard kitchen and bathroom fixtures, carpet and vinyl |
| Mid range | $3,900 to $4,500 | Custom design, feature cladding, tiled showers, stone benchtops, better heating |
| High spec | $4,500+ | Architectural features, premium cladding, higher studs, bespoke joinery |
House build only. Excludes land, site works, consent, development contributions, landscaping and service connections.
What does that look like by home size?
| Home size | Entry level | Mid range | High spec |
|---|---|---|---|
| 100 m² (2 bed) | $350,000 to $390,000 | $390,000 to $450,000 | $450,000+ |
| 150 m² (3 bed) | $525,000 to $585,000 | $585,000 to $675,000 | $675,000+ |
| 200 m² (4 bed) | $700,000 to $780,000 | $780,000 to $900,000 | $900,000+ |
| 250 m² (4 to 5 bed) | $875,000 to $975,000 | $975,000 to $1,125,000 | $1,125,000+ |
These are typical market ranges for planning. Your section, design and specification will move them, which is why a site visit matters before you rely on any number.

What costs sit outside the house price?
This is where Franklin budgets most often come unstuck. The house rate gets all the attention, and the site costs get discovered later.
How much do site preparation and earthworks cost?
Franklin has everything from volcanic clay to peat, plus plenty of sloping sections. Soft ground may need deeper piles or a specifically engineered slab. Slopes may need retaining and extra drainage. As a planning rule, set aside a meaningful allowance for earthworks and foundations before you look at a single kitchen tap, and get a geotechnical report early so that allowance becomes a real number.
What if your section isn’t on town supply?
Many lifestyle blocks around Franklin are not connected to council water or wastewater. That typically means:
- Water tanks for roof-collected water
- An on-site wastewater system designed for your soil and section
- Access improvements, such as a longer driveway or culverts
On rural or unserviced land, these can add $15,000 to $40,000 or more. In newer subdivisions, connections are usually provided to the boundary, so confirm exactly what is there before you buy.
Which council will you deal with?
Franklin straddles two councils, and it matters for your budget:
- Auckland Council covers areas such as Pukekohe, Waiuku, Patumahoe and Karaka.
- Waikato District Council covers areas such as Tuakau and Pokeno.
Each council has its own building consent fees, processing and development contribution policies. Check which one applies to your section on day one. See Auckland Council building and consents or Waikato District Council.
What are development contributions?
Councils may charge development contributions on new dwellings to help fund infrastructure such as roads, water and parks. The amount depends on your council and the specific area, and on some sites it can run to tens of thousands of dollars. These contributions are an additional cost if payable, so ask the council to confirm the outstanding amount for your address, taking account of any existing credits or contributions already paid at subdivision.
How much are consent and professional fees?
The conventional homes of 100 m² or more covered in this guide need a building consent, structural engineering and, on many Franklin sites, a geotechnical report. Consent fees vary by council, project value and complexity, so get a current figure from Auckland Council or Waikato District Council for your address before you lock in a budget. Design costs vary widely: choosing from a builder’s existing plans is usually the most cost-efficient route, while fully custom architectural design generally runs at 5% to 15% of the build cost.
Once the build is finished, the council issues a Code Compliance Certificate (CCC) confirming the work matches the consent. Banks and insurers usually want to see it, so allow time for it in your plans.

| Item | Estimated cost (NZD) |
|---|---|
| House build (150 m² x $3,900 to $4,500/m²) | $585,000 to $675,000 |
| Site preparation and foundations (flat, serviced site) | $15,000 to $30,000 |
| Design and engineering (builder plan, adapted) | $15,000 to $30,000 |
| Building consent and inspections | Varies by council (confirm for your address) |
| Driveway, paths and basic landscaping | $15,000 to $35,000 |
| Contingency (10%) | $63,000 to $77,000 |
| Total (excluding land, consent fees and development contributions) | $693,000 to $847,000 |
Illustrative planning figures only, not a quote. Land and consent fees are extra, as are development contributions if payable. Confirm consent fees and any outstanding contributions with your council, including existing credits or payments already made at subdivision.
Is it cheaper to build new, renovate, or buy a relocatable?
Each route has trade-offs worth weighing honestly:
- Relocatable homes can cost less up front, but banks often want a larger deposit because the house isn’t fixed to the land until late in the process.
- Renovating an older Franklin home can save on the shell, but opening walls often uncovers rewiring, repiling or insulation work. My guide to home addition and extension costs covers that side in detail.
- Building new gives you a home built to the current Building Code, lower near-term maintenance and full control over layout.
How do you get bank approval before you have a fixed price?
It’s a common chicken-and-egg problem. Banks want certainty before they lend, but you can’t get a firm contract price until the design is done. The way we work through it at Rag Reno’s (see How We Work):
- Concept and quote: once the design brief is signed off, you get a concept with a preliminary budget proposal.
- Transparent estimate: after the detailed design site visit and plan sign-off, you get a full estimate with specs and standard inclusions. Ask your bank or broker what they need from you at this stage.
- Working drawings and consent: specs and selections are locked in, trades walk the site, and the consent is submitted.
- Fixed-price quote review: we go through the fixed-price quote face to face before you sign, so the final number shouldn’t surprise you.
How do progress payments work?
Across the industry, most residential build contracts are paid in stages as work is completed rather than all at once. The exact stages and amounts depend on the contract, so check the payment schedule carefully and share it with your bank early.
Should you choose a fixed-price contract?
At Rag Reno’s we work to a fixed-price quote: what we price is what you pay. With a fixed-price contract, you agree the price for a defined scope up front, and cost movements within that scope are the builder’s risk rather than yours. A cost-plus contract passes every price movement during the build back to you.
Before you sign any contract, check:
- Which items are provisional sums or PC sums, and are the allowances realistic?
- How are variations priced and approved?
- What happens if the programme runs late?
It’s also worth knowing what is and isn’t included in new build costs so nothing lands as a surprise later. MBIE’s guide, Why contracts are valuable, is a good plain-language read.

How long does a new build take in Franklin?
Plan for roughly 14 to 22 months from first conversation to handover, depending on consent processing, site conditions and weather. Straightforward builds on flat, serviced sections sit at the shorter end.
| Phase | Typical duration |
|---|---|
| Feasibility and design | 1 to 3 months |
| Plans, engineering and consent | 3 to 6 months |
| Pre-construction preparation | 4 to 8 weeks |
| Construction | 6 to 12 months |
| Inspections, CCC and handover | 4 to 8 weeks |
For the stage-by-stage detail, see the new build timeline guide for Franklin.
What causes budgets to blow out on Franklin builds?
⚠️ Red flag: a low per square metre rate given over the phone without anyone seeing your section. It is almost always a house-only number, and the site costs will arrive later.Common causes include:
- Site costs found late: ground conditions, drainage or services discovered after pricing.
- Unrealistic PC sums: a kitchen allowance that won’t cover the kitchen you actually want.
- Design before budget: detailed drawings finished before anyone priced them against your lending.
- Changes mid-build: each variation adds cost and time.
How I approach new builds in Franklin
It starts with a free consultation with me (normally valued at $300). If needed, we request your council property file on that first call, then we visit your section before anything is designed. Trades walk the site before the consent goes in, and you review the fixed-price quote with us face to face before you sign.
Throughout the build we work to our 151-point quality check. Your home is backed by the 10-year Master Build Guarantee plus the Rag Reno’s Guarantee, and we check in at 3, 6 and 12 months after you move in. You can see one of our completed new builds, a four-bedroom home delivered on time and within budget, in the Kennelly Cres project.

Frequently asked questions
Is it cheaper to build or buy an existing home in Franklin?
Buying is usually cheaper up front. Building new gives you a home to current Building Code standards, lower near-term maintenance and control over layout and energy performance. If you already own land, building often stacks up better over the long term.
Can I get a fixed price before I have full plans?
Not a binding one. No fixed price is possible without full plans and engineering. What you can get is a solid preliminary budget estimate from concept plans, which is usually enough for bank pre-approval.
Do I need a geotechnical report for a new build in Franklin?
In most cases, yes. Franklin soils vary a lot, from peat to clay, and a geotech report is how the foundations get designed correctly for your site.
How much deposit do I need for a new build?
It depends on your lender and situation. New builds can sometimes qualify for lower deposits than existing homes, but talk to your bank or broker early.
What financial help is available for first home buyers?
The First Home Grant closed to new applications on 22 May 2024. Eligible KiwiSaver members may still be able to withdraw savings towards a first home, and a First Home Loan may lower the deposit for qualifying buyers. Check current options with Kāinga Ora before building any assistance into your budget.
How much contingency should I allow?
At least 10% of the total project budget. If your site has unknowns such as soft ground or no town services, 15% is safer.
What’s the next step for your Franklin new build?
The cost to build a new home in Franklin is the sum of the house, the section, the council and the contract. Get clear numbers on all four before you commit, and you avoid the surprises that derail most budgets. For the bigger picture, start with The Ultimate New Home Guide.
