Architect vs Architectural Designer vs Draftsman: Who Do You Need? (NZ 2026)

Architect, architectural designer and draftsman are three different roles with three very different price tags — and for most renovations and extensions you don’t need the most expensive one. The trick is matching the role to the project.

Homeowners often assume they need a registered architect, then get a shock at the fee. In reality, the right design professional depends on the complexity of your project — and for a typical renovation or extension there are better-value options that still deliver excellent design.

This guide explains the roles and who to hire for what.

The three roles

• Registered Architect. Tertiary-qualified and registered, able to handle the most complex, bespoke or large-scale work. The highest fees, and worth it for architecturally ambitious projects.
• Architectural Designer / Technician. Often LBP-design licensed, specialising in residential renovations, extensions and new homes. Excellent design at a more accessible fee — the sweet spot for most renovation work.
• Draftsman. Produces the technical drawings to document a design. Best when the design is already largely decided and you mainly need consent-ready documentation.

Architectural Designer	Most renovations & extensions	Mid
Draftsman	Documenting an already-decided design	Lowest

Which one for your project

For a standard renovation or extension — a rear addition, a second storey, a reworked layout — a good architectural designer usually delivers everything you need at a fraction of an architect’s fee. Reserve a registered architect for genuinely complex or design-led builds. Use a draftsman only when the design is settled and you need drawings.

The design-and-build alternative

There’s a fourth path that sidesteps the choice: design-and-build, where the design professional sits on the same team as the Quantity Surveyor and builder. You get design and real-time pricing under one contract — which avoids the “beautiful design you can’t afford” problem that catches so many homeowners who engage a designer in isolation.

What they cost

Design fees are typically quoted as a percentage of build cost or a fixed fee, rising with complexity and the seniority of the role. The headline number matters less than the value: a design that’s costed as it’s developed and actually gets built is worth far more than a cheaper set of drawings that never leaves the page.

Design professional FAQs

A registered architect is tertiary-qualified and registered for the most complex work; an architectural designer (often LBP-design licensed) specialises in residential renovations and extensions at a more accessible fee; a draftsman produces technical drawings to document a design that’s already largely decided.

Usually no. For a standard renovation or extension, a good architectural designer delivers everything you need at a fraction of an architect’s fee. Reserve a registered architect for genuinely complex, bespoke or architecturally ambitious projects.

A draftsman generally has the lowest fee, but they’re best only when the design is already decided and you mainly need consent-ready drawings. An architectural designer offers the best balance of design input and value for most renovation projects.

Design-and-build puts the design professional on the same team as the Quantity Surveyor and builder, under one contract — so you get design and real-time pricing together. It avoids the common problem of a beautiful standalone design that turns out to be unaffordable to build.

Design fees are typically a percentage of build cost or a fixed fee, rising with complexity and the seniority of the role. The value matters more than the headline number — a design that’s costed as it develops and actually gets built is worth far more than cheaper drawings that never proceed.
