What does an architectural designer cost in NZ?

Three ways designers charge

Most residential architectural designers in NZ structure their fees one of three ways:

• Hourly. You pay for time. Open-ended, hard to budget against, and creates a perverse incentive — more time spent, bigger invoice. Useful for one-off advice, awkward for a 12-month design programme.
• Percentage of build cost. Fee is set at a percentage of the build. For an architectural designer (LBP) doing residential design + consent documentation, published practice fees in NZ cluster around 3–8% of construction. Simple new builds sit at the bottom of that band; complex design-led builds and renovations sit at the top. The downside of a pure percentage: the build cost moves through the design, so the fee is a moving number until late.
• Fixed fee per stage. A number agreed up front for each stage. Set once, doesn't change unless the brief or scope changes — and any change is agreed in writing first.

Stoak uses fixed-fee per stage for everything except the calculator's "working drawings" component, which is set as a percentage of build cost so the fee scales with the size of the project.

What the percentage actually is in NZ

A few realistic ranges for an architectural designer (NOT an architect) doing residential design + consent documentation only, ex everything else:

• Simple new build (regular section, NZS 3604 framing, off-the-shelf joinery): around 3–5% of construction.
• Designer / architectural new build (custom, complex site, sharper detailing): around 5–7%, occasionally 8% on a brief that asks for more.
• Renovation or extension: typically 1–2 percentage points above a comparable new build, because design effort per dollar of build is greater. So 6–9% is realistic for an established designer.
• Multi-unit / townhouses: usually quoted as a lump sum or higher percentage band. Per-unit design effort is high.
• Re-clad and relocation: usually a fixed concept fee + percentage on the working drawings, because the build value is small relative to the documentation work.

For a registered architect doing the same scope, fees are typically higher — published NZIA-aligned ranges sit around 9–12% for full service. For most residential briefs an architectural designer can deliver the same consent set for less; the differences are explored in the article on architect vs. designer vs. draftsperson.

A worked example

A 200 m² family home in Rotorua at $700,000 construction cost is a useful anchor:

• As an architectural designer fee: roughly $28,000–$45,000 + GST for design + consent documentation, depending on whether it's an everyday or designer brief.
• As a registered architect fee: typically $55,000–$85,000 + GST for the same scope.
• Plus consultants (engineer, geotech), council fees, surveyor where needed, builder's pricing — all paid direct to those parties, no margin.

Those numbers triangulate from published NZ practice rates. Specific projects vary. The calculator on /pricing returns Stoak's number on your specific brief.

How Stoak's calculator works

The calculator on /pricing builds a fee differently for each project type, because the workflow is genuinely different on each:

• New builds + multi-unit + designer briefs: a fixed concept-design fee, a fixed developed-design fee, and a percentage of the developed design build cost for the working-drawings stage. The percentage isn't guessed — at the end of concept, the design is run through the QS software Stoak uses for a build cost estimate, and developed design reconciles the design with that number before working drawings start. The percentage is locked at proposal — it doesn't track up if build cost grows during construction.
• Renovations and extensions: same three-stage structure, but at a slightly higher percentage band (similar to multi-unit) because design effort per dollar of build is greater. Pricing benchmarked against comparable past jobs rather than the software, which doesn't measure existing-conditions work cleanly.
• Re-clads and relocations: a fixed concept fee + working drawings as a percentage of build cost. No formal developed-design stage by default — the build cost estimate that sets the working-drawings fee comes from a builder's pricing exercise on the concept or benchmarking against comparable past jobs.
• Minor works: bespoke quote, typically $500–$3,000 + GST. Build budgets are too small for a percentage to make sense.
• Feasibility study: flat $500 + GST, written report, credited against the first stage's design fee if you proceed.

That structure is the indicative number. The actual proposal is fixed-fee, written, and only changes if the brief changes.

Why not just quote a single number?

A "$30,000 design fee" headline figure hides what's actually being delivered. The three-stage structure makes it clear:

• You can stop after concept if the project doesn't stack up. You haven't paid for the rest.
• The cost estimate at the end of developed design is the real test — the build can be priced before you commit to the full consent set.
• The working-drawings percentage scales fairly: a more complex build takes more drawings.

What's not included in the design fee

The calculator covers Stoak's design fees only. Other costs that sit alongside the design — and aren't in the fee — typically include:

• Council fees (Building Consent lodgement, Resource Consent if needed). These vary by council and project size.
• Engineer's fees for structural design, geotechnical reports, fire engineering.
• Surveyor's fees if a site survey is needed.
• Specialist consultants where a project needs them (acoustic, traffic, ecology, heritage).

Each of these is invoiced direct to you by the consultant — not through Stoak. But you don't have to manage any of it. We handle all the communication and engagement with consultants on your behalf — briefing them, sending the drawings they need, chasing answers, pulling their work back into the consent set. You just pay the bill when it lands.

At the Working Drawing Pricing stage we pull together prices for all of it — design, consultants, council fees — and write them into the quote. That way you can see the whole picture of what the project will cost before committing to construction, not just the design slice of it.

What changes the fee after sign-off

A fixed-fee assumes a fixed brief. The two things that legitimately move the number after signing are:

• A brief change. You decide to add a storey, switch the structural system, redo the kitchen layout late. Fresh scope = a written variation.
• Site or council surprises. Geotech finds something the soil report didn't predict; council asks for a fire-engineered solution nobody had budgeted for. Project-side, not designer-side.

Anything else — extra coordination meetings, the normal back-and-forth of design — is in the original number.

Run your project through the calculator

The fastest way to see what your specific project would cost: pick the closest type, slide your build budget, send the result through. You'll have a fixed-fee proposal back within a business day.
