Questions and answers

Architect vs architectural designer NZ: what's the difference?

In New Zealand, “architect” is a protected title reserved for people registered with the New Zealand Registered Architects Board (NZRAB) under the Architects Act 1963. An architectural designer (or building designer) with LBP Design Class is a Licensed Building Practitioner who can design and sign off restricted building work, the structural and weathertightness parts of most homes and many commercial buildings. For most residential projects the practical scope is the same; the difference is the credential, not necessarily what gets built. Building Performance (building.govt.nz) lists both as recognised design professionals.

Do I need an architect or building designer for my project?

For most new homes, extensions, and renovations in New Zealand, you do not legally need a registered architect, you need someone licensed to design restricted building work, which an LBP Design Class holder can do. Registered architects are required only for specific building categories and some larger or higher-risk projects. If your project is a standard residential build or a light commercial building, an LBP architectural designer is usually the right hire. If you're unsure, a building designer can tell you quickly whether your project sits within LBP scope or needs NZRAB registration.

Can an LBP Design Class designer do the same work as an architect?

For restricted building work, which covers the design of most houses, extensions, and many commercial buildings, yes. An LBP Design Class holder can prepare your consent drawings, design the structure and weathertightness details, and provide the Record of Building Work required for consent. Registered architects can also do this work, and they are the only ones who can legally call themselves an architect. The Building Code does not require an NZRAB architect for the majority of residential and light commercial projects in New Zealand, see building.govt.nz for the official scope guidance.

Why do people search for an architect when they mean a designer?

Because most homeowners don't know the title distinction until they're deep into a project. People say “architect” the way they say Kleenex, they mean the person who draws the building, not necessarily someone with NZRAB registration. In NZ, that person is often an LBP architectural designer or building designer. The search term and the legal title don't always match, which is why understanding the credential matters more than the word people type into Google.

Is an architectural designer cheaper than a registered architect?

Often, yes, but not always because the work is lesser. LBP architectural designers typically carry lower overheads than large architecture firms, and for residential work the design scope is frequently identical. Fee structures vary: some charge a percentage of build cost (typically 5–12% for full design service on residential), others charge fixed fees by project stage. See our design cost guide for realistic NZ ranges. What you pay should reflect project complexity, not just the credential on the wall.

When would I actually need a registered architect (NZRAB)?

NZRAB registration is legally required for certain building types and Importance Level 3 or higher structures, think hospitals, large public buildings, and some complex commercial work. For a standard home, a rural lodge a warehouse or a home extension, an LBP Design Class designer is typically the correct and sufficient credential. If your project crosses into territory that requires NZRAB registration, a good LBP designer will tell you upfront rather than proceed without the right licence.
