An Honest Guide to Architectural Design Fees in NZ

Architectural design fees are one of the hardest costs to pin down early in a project.

Some firms charge a percentage of the build cost. Others work on fixed fees or hourly rates. And depending on the project, all three approaches can make sense.

The challenge is that no two homes, sites or scopes are exactly the same, especially in places like Dunedin and Otago, where steep sites, renovations and complex ground conditions are common.

Quick Summary

In New Zealand, residential architectural design fees are charged in any of the following: as a percentage of total build cost, as a fixed fee, or at an hourly rate. For a new build, the design fee usually ranges from 3% and 12% of the construction value. The exact figure depends on the level of service and project complexity. It also depends on whether you hire a registered architect or an architectural designer. Renovations tend to cost more, often 8% to 15% of the renovation cost. Council fees, engineers’ or surveyors’ fees are yet to be added. A good designer will give you a written fee proposal that is clear and transparent before you commit.

How Architectural Design Fees are Calculated in NZ

Architectural design fees NZ-wide are set according to one of three fee structures: as a percentage of the build cost, as a fixed fee (sometimes called a lump sum fee), or at an hourly rate. Most residential design fees range between 3% and 12% of total construction cost, depending on the scope of work the designer is taking on.

For a standard residential new build, an architectural designer providing concept through to building consent documentation will often sit around the 3% to 5% range. Registered architects generally charge more, particularly on larger or more complex homes.

Percentage fees tend to work well early in a project when the build cost is still evolving. Fixed fees are often preferred once the scope and brief are clearly defined. Hourly rates are more common for smaller jobs, feasibility work, or early-stage consultation. MBIE’s Building Performance guidance provides more details on these three fee structures and recommends agreeing on the pricing approach early in the process.

Architect vs Architectural Designer: The Cost Difference

The cost of hiring a registered architect in NZ is generally higher than hiring an architectural designer for comparable residential work. This is true even if the design quality of most homes is equivalent. Registered architects belong to NZIA and tend to charge a higher percentage of the build cost for full services, particularly on complex projects.

Architectural designers with ADNZ Professional Membership and Licensed Building Practitioner Design 2 accreditation generally charge less for a similar scope. The difference lies in the qualification path, not the standard of the drawings, the design process, or the consent.

So, how much does an architectural designer cost in NZ?

The same factors that affect any design fee apply: complexity, site, finish level, and how involved the designer is throughout construction.

The figures above are indicative. A 200m² home at 5% comes in at around $35,000 plus GST, regardless of the title on the door, so the better question is fit rather than label.

What Changes the Fee for Your Project

There are three reasons why the design fee may change: the project’s site, scope, and complexity. Even a single designer can quote two very different fees on two very similar homes once those three variables come into play.

According to a Wise Move analysis of building consent data, Otago is currently the most expensive region in New Zealand to build, at around $3,900 per square metre, up roughly 20% from 2023. A higher build cost directly influences its percentage fee. This is why a fixed fee often suits Otago projects better.

Some of the biggest factors that affect design fees include:

• Site conditions. A flat section in central Dunedin with town services at the boundary is straightforward work. A steep Otago Peninsula site, in contrast, is harder because it needs a geotechnical report and a retaining strategy.
• Scope of service. A “concept and consent only” engagement costs less than full documentation with construction observation. Decide early how far through the build you want the designer involved.
• Project complexity. Heritage rules, sloping sections, split-level layouts, and unusual cladding details all push design fees up. They genuinely need more time to accomplish.
• Build budget. Percentage fees scale with construction value, so the same design effort on a $1.2 million build will cost more than on a $600,000 one.
• Renovation vs new build. Renovations sit at the top of the fee range (often 8% to 15% of the renovation cost), because integrating a new design with an existing structure is more complex than starting fresh.

What’s Not Included in Your Design Fee

Design fees cover the design work and not much beyond it. Consultant fees, council charges, and site costs all sit outside the design fee.

A clear fee proposal lists all of these up front as exclusions, with realistic estimates against each one, so you can budget for the whole project rather than just the drawings.

Here’s what you’ll usually need to fund on top of the design fee on a typical Dunedin new build:

• Building consent fees (Dunedin City Council): $5,000 to $10,000 plus GST, depending on scope.
• Structural engineer: $2,000 to $5,000 for a standard residential job; more if the structure is complex.
• Geotechnical report: around $3,500 on hill or flood-prone sites, often required by council or your insurer.
• Surveyor: $1,500 to $5,000 where boundaries, levels, or contours need to be confirmed.
• Resource consent (where required): additional council fees if the project triggers planning rules.
• Site works and utility connections: earthworks and retaining, plus connections for water, sewer, power, and telecoms, all priced separately.
• Specialist consultants: kitchen designer, landscape designer, interior fit-out, fire engineer or acoustic engineer, depending on the brief.

How Eco Workshop Quotes Design Fees

Eco Workshop quotes every project individually, and you’ll see the numbers before you sign anything. Your first meeting is free and no-obligation, and it’s a conversation about what you need, not a sales pitch.

The Eco Workshop team will look at the site and the brief with you. They’ll then walk you through how the four-stage architectural process applies to your project: Preliminary, Concept Design, Developed Design, and Detailed Design and Documentation.

The studio then puts together a written fee proposal that breaks down each stage. You’ll see what’s included and what’s excluded at every step. You’ll also see where consultant and council costs are likely to land. For clients who’d prefer a fixed price for design and construction, the same conversation can be routed to Your Way Home, the studio’s design-and-build pathway.

Thinking About a New Build or Renovation?

Whether you’re planning a new build, a major renovation or simply exploring what’s possible on your site, having a clear conversation early can save a lot of stress later.

Eco Workshop works across Dunedin and the wider Otago region on residential new builds, renovations and alterations, with a strong focus on practical, liveable design.
