Quick answer: Architectural plans in New Zealand cost between 1% and 15% of the total build cost, depending on who you engage and how far you take the design. A draftsman producing consent-ready drawings sits around 1–4%. A full-service architectural designer (LBP-licensed) typically runs 8–12% of build cost for concept-to-CCC. A registered architect through to construction observation runs 10–15%+. On a typical $750,000 Auckland build, that’s $7,500 for drafting-only at one end, $60,000–$112,500 for full architectural service at the other. The right number depends on the complexity of your project, not on shopping for the lowest percentage.
Below: what each tier actually delivers, where the contradictions in NZ design fee advice come from, the real cost of a draftsman, and how to work out which path fits your project.
Why “What Do Architectural Plans Cost?” Doesn’t Have One Answer
The reason fee ranges quoted online vary so wildly — anywhere from 3% to 15% — isn’t that the industry is inconsistent. It’s that the question is incomplete. “Architectural plans” can mean any of four very different deliverables, and the fee tracks the deliverable, not the title on the business card.
These are the four tiers in NZ residential work, in increasing scope:
- Drafting / technical drawing only — A draftsman takes your design intent (or a builder’s sketch) and produces consent-ready working drawings. No design input, no consultant coordination. Typical cost: 1–4% of build cost, or a fixed fee of $1,500–$4,000 for straightforward projects.
- Concept design only — An architectural designer or architect develops the design to concept stage — floor plans, elevations, the look and feel — but stops before detailed documentation. Typical cost: 3–5% of build cost.
- Full architectural service through consent — Concept → developed design → detailed design → consent documentation → consent submission. The plans are good enough to build from and the consent has been won. Typical cost: 8–12% of build cost for an LBP-licensed architectural designer; 10–15% for a registered architect.
- Full service plus construction observation and PM — As above, plus regular site visits during construction, variations management, and coordination with builder, engineer, and council. Typical cost: 12–18% of build cost.
If you’ve seen a “3-5%” figure quoted on one page and “9-12%” on another, you weren’t looking at contradictory advice. You were looking at concept-only at one end and full service at the other.
Architectural Plans Cost per Square Metre
Asking about cost per square metre for architectural plans is the wrong unit. The fee is anchored to total build cost, not floor area. But because the question gets asked constantly, here’s the relationship:
NZ residential build costs in 2026 run roughly:
- $3,500–$5,500 per m² for standard-quality builds
- $5,500–$7,500 per m² for architecturally-designed mid-range
- $7,500–$10,000+ per m² for high-end and complex sites
Apply the 8–12% full-service fee to that. A 200m² architecturally designed home at $6,000/m² is a $1.2m build. Full-service architectural fees on that project land in the $96,000–$144,000 range — which is the same as $480–$720 per m² of floor area, if you really want a per-m² figure.
One reason this matters: a smaller home doesn’t get cheaper design fees in proportion. The work to design a 120m² house is closer to 80% of the work to design a 220m² house, not 55%. Fee percentages often climb on smaller projects because the fixed-cost design effort gets spread across a smaller build budget.
Architectural Designer vs Architect vs Draftsman — The Legal Distinction
The titles are not interchangeable in New Zealand, and the distinction matters more than most homeowners realise.
Architect is a legally protected title under the Registered Architects Act 2005. Only people registered with the New Zealand Registered Architects Board (NZRAB) can call themselves architects. To register, you need a Master of Architecture, three years of supervised experience, and you have to pass the registration exam. Architects typically work on commercial, institutional, and high-end residential projects, and their fees reflect that.
Architectural designer is the term for professionals who do architectural design but aren’t NZRAB-registered. The serious ones hold LBP Design Class licences under the Building Act, which gives them the legal authority to design and supervise Restricted Building Work — most structural residential design — and to sign the Records of Work councils require. Architectural designers typically work on residential renovations, new builds, and extensions, and their fee structures are usually 10–25% lower than registered architects for equivalent scope.
Sonder is an architectural design practice — our team holds LBP Design Class licences. We’re not registered architects, and we’re careful about that distinction. For most residential work in Auckland, an LBP Design Class designer can do everything you’d need an architect for, including signing off Restricted Building Work documentation. We’ve covered the full distinction between architects, designers, and builders in a separate piece.
Draftsman (or draughtsperson) is a technical role. Draftsmen produce drawings — they don’t typically lead design. Their work is ideal when you already know what you want to build and need someone to convert that into consent-ready documentation. Some draftsmen also hold LBP licences; many don’t.
How Much Does a Draftsman Cost in New Zealand?
If you’re planning a renovation or new build in New Zealand, you might be weighing whether you need an architect, an architectural designer, or a draftsman. For homeowners with a clear design brief, hiring a draftsman is the most cost-effective option — particularly for straightforward projects without complex design requirements.
What a Draftsman Does
A draftsman specialises in the technical side of building design. They don’t usually provide creative architectural design services, but they produce the working drawings and plans required for council approval and construction. Their work suits:
- Standard home designs and renovations
- Converting concept sketches into formal building plans
- Preparing documentation for building consent
- Simple extensions or alterations
- New builds without complex architectural design requirements
If your project requires custom design, unusual materials, structural complexity, or coordination with multiple consultants, an architectural designer or architect is the better fit.
Draftsman Costs
Draftsmen generally charge between 1% and 3% of the total project value. That makes them a more affordable alternative to architects or architectural designers, whose fees typically range from 8% to 15% for full service.
Example cost breakdown:
- For a $500,000 project:
- At 1%: $5,000 + GST
- At 3%: $15,000 + GST
- For a $750,000 project:
- At 1%: $7,500 + GST
- At 3%: $22,500 + GST
The exact cost depends on design complexity, council requirements, and the level of service. Some draftsmen charge a fixed fee per project — especially for small jobs like minor renovations, garage conversions, or basic plans. Fixed fees for simple residential drafting typically sit between $1,500 and $4,000.
When a Draftsman Is the Right Choice
A draftsman is the right call if:
- You have a clear design and just need technical drawings
- The project is straightforward — a minor renovation, an extension that copies the existing form, or a build from existing house plans
- You want to keep upfront design costs low
It’s not the right call if you need design help, sustainability input, structural problem-solving, or someone to coordinate the consent process. Those are architectural designer or architect jobs.
Architect and Architectural Designer Fees — The Full Picture
For homeowners who want design expertise rather than just drawings, fees scale with the depth of involvement. Here’s how the tiers map out in NZ residential work.
Concept design only — 3–5% of build cost
You engage a designer to develop the concept — floor plans, elevations, key design decisions — but you take it from there with a builder or a draftsman for the consent documentation. Suits homeowners who want a designer’s eye on the layout but plan to value-engineer or detail the rest themselves.
On a $600,000 build: $18,000 – $30,000.
Full architectural service — 8–12% of build cost (architectural designer) or 10–15% (registered architect)
The standard residential package. Concept, developed design, detailed design, consent documentation, consent lodgement, response to council RFIs, and a Code Compliance Certificate at the end.
For an LBP-licensed architectural designer on a $800,000 build: $64,000 – $96,000.
For a registered architect on the same build: $80,000 – $120,000.
Full service plus construction observation — 12–18% of build cost
As above, with regular site visits during construction, attendance at site meetings, variation management, builder/engineer coordination, and snag-listing at completion. Suits high-value or design-led projects where the homeowner wants the designer present through to handover.
On a $1,000,000 build: $120,000 – $180,000.
What changes the fee within these ranges
- Project complexity — A single-storey extension on a flat site is at the low end. A second-storey addition to a heritage villa with a steep section sits at the top.
- Site conditions — Sloping sections, flood zones, coastal sites, and heritage overlays all add design work and council coordination.
- Consultant coordination — Projects requiring structural engineering, geotechnical reports, fire reports, or specialist services add to the architectural workload.
- Council jurisdiction — Auckland Council consent processes have specific complexity (Unitary Plan overlays, Watercare requirements, viewshafts) that can add 1–2% to the fee compared to simpler council jurisdictions.
- Fee structure — Some designers charge fixed fees, some charge time-and-materials, most charge percentage of build cost. Each has tradeoffs; we explain how Sonder structures fees in our design process guide.
Architectural Plans Cost for Renovations
Renovation design fees usually sit 2–4% higher than equivalent new-build fees as a percentage of project value, because renovations require more design problem-solving per square metre. You’re working within an existing structure, fitting new systems into old ones, and often dealing with surprises mid-build.
Typical fee ranges for common Auckland renovations:
| Renovation type | Build cost range | Typical design fee (10–15%) |
|---|---|---|
| Kitchen renovation | $40,000 – $80,000 | $4,000 – $12,000 |
| Bathroom renovation | $25,000 – $50,000 | $2,500 – $7,500 |
| Internal layout reconfiguration | $50,000 – $150,000 | $5,000 – $22,500 |
| Single-storey extension (50–100m²) | $200,000 – $450,000 | $20,000 – $67,500 |
| Second-storey addition | $350,000 – $650,000 | $35,000 – $97,500 |
| Full home renovation | $400,000 – $900,000 | $40,000 – $135,000 |
| Recladding | $200,000 – $400,000 | $20,000 – $60,000 |
| Garage conversion | $60,000 – $150,000 | $6,000 – $22,500 |
The renovation cost numbers above reflect 2026 Auckland build pricing — they’re higher than the 2024 figures most homeowners remember. Whether the architectural fee is worth it on smaller renovations is a question we’ve covered in detail.
What’s Not Included in the Architectural Fee
Design fees cover the architectural work. Several other costs sit outside that and have to be budgeted separately.
- Geotechnical report — Required for most new builds and some larger renovations. $3,000 – $5,000.
- Structural engineering — For consented work involving structural change. $2,500 – $6,000 for typical residential.
- Surveying — Topographical and boundary surveys. $1,500 – $5,000 depending on site complexity.
- Fire engineering — For multi-unit or commercial-adjacent residential. $2,000 – $5,000.
- Council consent fees — Building consent typically $2,000 – $10,000+ for residential work; resource consent (if needed) $3,000 – $15,000+. See our Auckland consent cost guide for detail.
- Development contributions — Charged on new dwellings, typically $15,000 – $40,000 in Auckland depending on zone and infrastructure load.
- Site preparation — Earthworks, retaining, services connections. $10,000 – $80,000+ for difficult sites.
On a typical mid-range Auckland new build, these consultant and council costs add $25,000 – $60,000 on top of the architectural fee.
How Sonder Approaches Plans Cost
Most architectural design conversations start with a fee discussion before the project scope is properly understood. We work the other way around: we run a Free Feasibility Report first to confirm what your site can support, what the realistic build cost looks like, and which service tier actually fits the project. From there the fee is a calculation, not a negotiation.
Sonder’s designers hold LBP Design Class licences. That matters because most residential design — anything involving structural work — is Restricted Building Work, and only licensed practitioners can produce documentation councils accept. The licence is also the reason an LBP-designed project carries the same legal weight as a registered-architect-designed project for residential work, at typically 20–25% lower fees.
If you’re early in thinking about a renovation, new build, or minor dwelling and want to know what the design and build will realistically cost on your site, the feasibility report is the starting point.
How much do architectural plans cost in NZ?
Architectural plans cost between 1% and 15% of total build cost in NZ, depending on the service level. Drafting only runs 1–4%. Full architectural service from an LBP-licensed architectural designer is 8–12% of build cost; a registered architect runs 10–15%. On a $750,000 build that's $7,500 at the low end for drafting through to $112,500+ at the high end for full architectural service.
How much does a draftsman cost in NZ?
Draftsmen typically charge 1–3% of total project value, or fixed fees between $1,500 and $4,000 for straightforward projects. On a $500,000 project that's $5,000–$15,000 + GST. Drafting only covers technical drawings — no design input or consent coordination.
What's the difference between an architect and an architectural designer in NZ?
Architect is a protected title under the Registered Architects Act 2005 — only NZRAB-registered professionals can use it. Architectural designers do architectural design but aren't NZRAB-registered; the serious ones hold LBP Design Class licences, which gives them legal authority to design and supervise Restricted Building Work. For most residential projects an LBP-licensed designer offers equivalent service at 20–25% lower fees than a registered architect.
Are architectural fees worth it?
For straightforward work where you have a clear design, a draftsman at 1–3% is sufficient. For projects involving structural change, complex sites, heritage overlays, or design problem-solving, an architectural designer or architect typically saves more than the fee costs — through better space planning, fewer build-stage variations, and stronger consent outcomes.
What's included in architectural design fees?
Full architectural service covers concept design, developed design, detailed design, consent documentation, consent submission, RFI response, and CCC. Construction observation (regular site visits during construction) is usually charged separately or as an upper-tier service. Excluded: engineering, geotechnical, fire reports, council fees, development contributions — these are consultant and council costs paid separately.
How much do architectural plans cost for a renovation in NZ?
Renovation design fees typically run 10–15% of project value (slightly higher than new-build percentages because renovations require more problem-solving per square metre). A $50,000 bathroom renovation might involve $5,000–$7,500 in design fees; a $400,000 full home renovation $40,000–$60,000+.
Do you need an architect to draw house plans in NZ?
No — you can engage an architectural designer or draftsman instead. Most NZ residential projects use architectural designers (LBP-licensed) rather than registered architects. For Restricted Building Work (most structural residential), the designer or architect must hold the appropriate LBP licence to sign off Records of Work.
