Who should draw building plans in NZ?

A practical guide to architects, designers and draughtpersons

Why are building plans so important?

Building plans are a key part of your building consent application and must comply with the Building Act and Building Code. They set out exactly how your home will be built, from structure and materials to layout and finishes.

Throughout the build, council inspectors will check that the work matches the consented plans. Once complete, a Code Compliance Certificate (CCC) is issued, and your plans become a permanent record of the work.

In short, good plans don’t just look great on paper, they help avoid delays, reduce costs and ensure a quality result on site.

Who should draw building plans in NZ?

In New Zealand, building plans are typically prepared by one of three professionals:

• A registered architect is best for complex or high-end projects where design, detail and coordination are critical.

• An architectural designer is a great middle ground, offering strong design and technical knowledge for renovations and additions.

• An architectural draughtsperson is typically suited to straightforward projects with minimal design requirements.

The right choice depends on the complexity of your project, your budget and how much design input you need.

Great building plans are the foundation of any successful build or renovation.

They don’t just bring your ideas to life, they’re essential for council consent, guide every trade on site and ultimately determine how smoothly your project runs.

If you’re planning a new build or renovation in Auckland, one of the first questions you’ll face is: who should draw your building plans?

Do building plans need to be done by a Licensed Building Practitioner (LBP)?

If your residential project includes Restricted Building Work (RBW), such as structural or weathertight elements, the design must be carried out or supervised by a LBP. Fire safety design in small to medium-sized apartment buildings and co-joined minor dwellings also need to be drawn by an LBP. This is a legal requirement that protects both you and future owners of the property. It ensures:

• Your home is structurally sound

• Work meets Building Code standards

• There is accountability for the design and construction

What does an architect do?

A registered architect likely has an architectural degree and must hold a practising certificate issued by the New Zealand Registered Architects Board (NZRAB). Members of the NZRAB are automatically considered LBPs in the design class. Many architects also belong to the New Zealand Institute of Architects (NZIA).

A registered architect is trained to manage the entire design process, from concept through to completion. They bring creativity and problem-solving to complex projects, helping you achieve a result that’s both functional and visually exceptional. They consider:

• Layout, flow and functionality

• Aesthetics and design detail

• Site conditions, sun and orientation

• Coordination with engineers and consultants

Architects are ideal for:

• New builds

• Major renovations

• Architecturally designed homes

What does an architectural designer do?

An architectural designer probably studied at a tertiary institution and is specifically trained in the technical aspects of design. They should also be familiar with Building Code and local council requirements, such as building and resource consents. An architectural designer may not necessarily be an LBP, so you’ll need to check. Many architectural designers are represented by Architectural Designers New Zealand (ADNZ).

An architectural designer focuses on practical, buildable design solutions and is often involved from concept through to consent. They typically:

• Prepare detailed plans for council approval

• Understand Building Code requirements

• Design functional layouts for everyday living

Architectural designers are well suited to:

• Renovations and extensions

• Adding rooms, garages or sleepouts

• Decks and structural alterations

When should you use a draughtsperson?

An architectural draughtsperson will usually have technical institute training. They can take your ideas and turn them into technical drawings for your builder.

They are generally best suited to:

• Simple renovations

• Kitchen or laundry upgrades

• Projects with no structural changes

While a draughtsperson can be a cost-effective option, they typically offer less design input. If your project involves restricted building work, you’ll need to ensure they are an LBP or working under one.

How much do building plans cost in NZ?

The cost of building plans varies depending on the complexity of your project and who you engage. As a general guide:

Draughtsperson: lower cost, suitable for simple work

Architectural designer: mid-range, good balance of design and practicality

Architect: higher cost, best for complex or high-end projects

While it can be tempting to go for the cheapest option, poorly prepared plans often lead to costly changes, delays and frustration later on. If you have a limited budget, a skilled architect or designer can explore ways to make your budget and ideas fit, as well as efficiently navigate the building and resource consent processes.

Choosing who draws your building plans is a key decision that will influence every stage of your project. Whether you’re planning a new build or renovation in Auckland, the right combination of design expertise and practical input will set you up for success.

If you’re not sure where to start, we’re here to help. Qualitas Builders can guide you through the process, collaborate with your architect or designer and ensure your project runs smoothly from concept to completion.

What building plans are required for council consent in Auckland?

For building consent in Auckland, your plans need to be detailed and accurate. They typically include:

• Site plans and elevations

• Floor plans and layouts

• Structural details

• Materials and specifications

Incomplete or unclear plans are one of the most common causes of consent delays. Getting it right from the start can save weeks, or even months, in the approval process.

Should your builder be involved in the design stage?

Bringing your builder in early is one of the smartest decisions you can make. An experienced builder can:

• Provide practical advice on buildability

• Help align design with your budget

• Identify potential issues before they arise

• Streamline the transition from design to construction

Qualitas Builders regularly work alongside architects and designers from the early stages, helping refine plans so they work just as well on site as they do on paper.

Frequently asked questions

Who can draw building plans in New Zealand?

Building plans in New Zealand can be drawn by a registered architect, architectural designer or draughtsperson. For projects involving restricted building work, the design must be completed or supervised by a Licensed Building Practitioner (LBP).

What is the difference between an architect and an architectural designer?

An architect typically handles complex, high-end projects and offers full design and project coordination. An architectural designer provides practical, cost-effective design solutions and is commonly used for renovations and residential additions.

How much do building plans cost in NZ?

The cost of building plans in NZ depends on the project’s complexity and the professional engaged. Draughtspersons are generally more affordable, while architects cost more but provide a higher level of design and coordination.

Should a builder be involved before building plans are finalised?

Yes, involving a builder early helps ensure the design is practical, aligns with the budget and avoids costly changes during construction.
