Guide to Architectural Plans Cost

Thinking about building a new home in New Zealand? One of the first big questions is: How much will the architectural plans cost? Whether you’re working with an architect or a draftsman, understanding the fees involved can help you budget wisely and avoid surprises. In this guide, we’ll break down everything you need to know—from cost per square metre to council fees—so you can plan your project with confidence.

1. How Much Does a Set of Architectural Plans Cost per Square Metre?

Planning a new home or renovation in New Zealand comes with various costs, and one of the first questions homeowners ask is: How much do architectural plans cost per square metre? Understanding this cost helps with budgeting and decision-making, ensuring you get the right level of design expertise for your project.

Breaking Down the Cost of Architectural Plans

The cost of architectural plans in New Zealand is closely linked to the overall construction cost, which typically ranges between $3,500 to $5,500 per square metre. However, for high-end homes, architecturally designed houses, or complex builds, this figure can be even higher.

Architectural design fees are generally calculated as a percentage of the total build cost, rather than a fixed per-square-metre rate. This percentage typically falls between 3% and 5%, depending on the scope of work and the level of service required.

Example Calculation: Architectural Fees as a Percentage of Build Cost

To put this into perspective, let’s take a typical new build project:

  • Total construction cost: $600,000 + GST
  • Architectural design fee at 5%: $30,000 + GST
  • Architectural design fee at 3%: $18,000 + GST

This fee covers the design process, from concept sketches to final working drawings needed for building consent. It does not include additional costs such as engineering reports, council consent fees, or site surveys, which should also be factored into your budget.

Factors Affecting Architectural Plan Costs

Several factors influence how much you’ll pay for architectural plans in New Zealand:

1. Project Complexity

A simple single-storey home with a standard floor plan will be less expensive to design than a multi-storey house with unique architectural features. Custom designs, sustainability features, or complex site conditions may increase costs.

2. Level of Design Involvement

Some architects offer full-service packages, covering everything from initial design concepts to project management. Others provide a more limited service, such as drafting plans based on your ideas. The more comprehensive the service, the higher the cost.

3. Size of the Home

Larger homes require more detailed planning and additional design time, which can increase architectural fees. However, the percentage charged may decrease slightly for larger projects, as some fixed costs remain the same regardless of size.

4. Council and Compliance Requirements

New Zealand’s strict building regulations mean that all homes must meet council requirements. Architects often work closely with councils to ensure compliance, which may add to design costs if extra documentation or revisions are needed.

Are Architectural Plans Worth the Investment?

While hiring an architect or architectural designer adds to your overall build cost, it can save you money in the long run. Well-designed plans can optimise space, improve energy efficiency, and increase the long-term value of your home. Investing in quality plans upfront can also help avoid costly mistakes or design flaws later in the construction process.

The cost of architectural plans in New Zealand varies depending on factors like home size, complexity, and the level of service provided. While there is no fixed per-square-metre rate for architectural design, homeowners can expect to pay between 3% and 5% of the total build cost. By understanding these costs and planning accordingly, you can ensure your project runs smoothly from concept to completion.

2. Architectural Fees Guidelines in New Zealand: What Homeowners Need to Know

When planning a new home or renovation in New Zealand, understanding architectural fees is essential for budgeting effectively. These fees can vary widely depending on the scope of work, project complexity, and the level of service provided. This guide breaks down architectural fee structures so you can make informed decisions.

How Are Architectural Fees Calculated?

In New Zealand, architectural fees are typically charged as a percentage of the total project cost rather than a flat rate. This ensures that the design work reflects the complexity and scale of the build.

Comprehensive Architectural Services (Full Package Fees)

For homeowners who want a complete architectural service—from initial consultation to final documentation—fees usually range from 9% to 12% of the total project cost (plus GST).

This full-service package includes:
✅ Concept development – Initial design ideas, sketches, and layout options
✅ Detailed drawings – Technical and structural details required for council approvals
✅ Consent documentation – Preparing and submitting documents for building consent
✅ Project coordination – Working with engineers, consultants, and councils to ensure compliance

Example:

  • Project cost: $800,000 + GST
  • Architectural fees at 9%: $72,000 + GST
  • Architectural fees at 12%: $96,000 + GST

A full-service package is ideal for complex builds, high-end homes, or projects requiring extensive coordination with engineers and local authorities.

Partial Architectural Services (Design-Only Fees)

For homeowners who only need assistance with the early design stages, architectural fees generally range from 7% to 10% of the project cost (plus GST). This option is suitable if you plan to manage some aspects of the project yourself or work with a separate builder or consultant for later stages.

A partial service typically includes:
🔹 Site analysis – Assessing the land and identifying design constraints
🔹 Preliminary design – Floor plans, elevations, and basic layouts
🔹 Concept approval – Refining designs before council submission

Example:

  • Project cost: $600,000 + GST
  • Architectural fees at 7%: $42,000 + GST
  • Architectural fees at 10%: $60,000 + GST

This option provides flexibility while still ensuring a professional design foundation for the build.

What Affects Architectural Fees?

Several factors influence how much you’ll pay for architectural services in New Zealand:

 

1. Project Complexity

A simple, single-storey home with standard features will require less design work than a multi-level house with intricate architectural details, custom materials, or challenging site conditions. More complexity means higher fees.

2. Scope of Work

Are you engaging an architect for full project management, or just the design phase? Comprehensive services cost more but provide a seamless experience, reducing the risk of errors or delays during construction.

3. Council Compliance and Documentation

New Zealand has strict building regulations, and architects play a key role in ensuring compliance. If your project requires additional consent documents or revisions, this may increase fees.

4. Customisation and Special Features

Unique architectural features, sustainability elements, or bespoke interior details can add to the design workload, increasing the percentage fee charged.

Are Architectural Fees Worth It?

While architectural fees may seem like a significant upfront cost, they are an investment in the success of your build. A well-designed home can:
✔️ Improve functionality and space efficiency
✔️ Increase property value
✔️ Avoid costly mistakes during construction
✔️ Ensure compliance with building regulations

 

Architectural fees in New Zealand range from 9% to 12% for full services and 7% to 10% for partial services, depending on the project’s complexity and scope. Understanding these costs upfront will help you budget effectively and choose the right level of service for your home build or renovation.

If you’re unsure about which service level suits your needs, it’s always a good idea to consult with multiple architects or architectural designers to compare fees, services, and expertise.

3. How Much Does a Draftsman Cost in New Zealand?

If you’re planning a home renovation or new build in New Zealand, you may be wondering whether you need an architect, an architectural designer, or a draftsman. For homeowners looking for a cost-effective option, hiring a draftsman can be a practical choice—especially for straightforward projects that don’t require high-end design work.

What Does a Draftsman Do?

A draftsman (or draughtsperson) specialises in the technical side of building design. While they don’t typically provide creative architectural design services, they can create the necessary working drawings and plans required for council approval and construction. Their work is ideal for:

✅ Standard home designs or renovations
✅ Converting sketches into formal building plans
✅ Preparing documentation for council consent
✅ Simple extensions or alterations
✅ New builds without complex architectural elements

If your project requires custom design, unique materials, or advanced structural considerations, you may need an architectural designer or architect instead.

Draftsman Costs in New Zealand

Draftsmen generally charge between 1% and 3% of the total project value. This makes them a more affordable alternative to architects or architectural designers, whose fees typically range from 7% to 12%.

Example Cost Breakdown

  • For a $500,000 project:
    • At 1%: $5,000 + GST
