Interior Architect vs. Interior Designer in New Zealand: What’s the Difference?
What’s the difference between an interior architect and an interior designer in NZ?
It’s a common question when starting a renovation or builidng a new home. The terms sound similar—but they focus on different stages of your home's creation.
If you're planning a design project in New Zealand, this guide will help you understand who does what, and when to bring each professional on board.
What Does an Interior Architect Do in New Zealand?
An interior architect focuses on the structure and spatial layout of a building’s interior. This includes:
Changing or designing internal walls, doors, staircases
Planning the flow of space and circulation
Collaborating with engineers and builders on layout
Ensuring compliance with NZ building codes
In New Zealand, "architect" is a protected title, which means someone must be registered with the NZ Registered Architects Board to legally call themselves an architect. However, some designers trained in spatial or architectural design (but not registered architects) still use the term "interior architecture" to describe their work.
What Does an Interior Designer Do?
An interior designer focuses on how a space feels and functions once the structure is in place. This includes:
Creating concepts looking at space planning, design features, light and flow.
Selecting colours, finishes, lighting, furniture, and materials
Designing kitchens, bathrooms, wardrobes, and custom joinery
Ensuring the overall look of a space is cohesive and works in with the architects plans.
Collaborating with trades and suppliers such as curtain makers, plumbers, upholsterers
Sourcing one-off pieces
Styling the final space
At Stacey Gillies Interiors, we specialise in creating interiors that are original and emotionally resonant. We stay away from trends, with designs informed through art, fashion, fabrics and the landscape. From material palettes to one-off artworks, every detail is carefully considered.

How We Work at Stacey Gillies Interiors
We love being involved early in the process, alongside your architect or builder, to ensure the interior vision isn’t an afterthought. Our clients often engage us from concept phase so that every colour, texture, and light source is purposeful and tailored to them.
We don’t do cookie-cutter. Our interiors are expressive, art-driven, and designed for the way you actually live. You can see this in this project portfolio here.
Quick Summary:
What’s the difference between an interior architect and interior designer in NZ?
An interior architect focuses on structure and space planning, such as moving walls as well as designing layouts and selecting finishes.
An interior designer works alongside the architect and builder and selects materials, furnishings, and details that shape how the space feels. An easy way to look at it is the hard and soft finishes as well as all the ‘loose pieces’ such as furniture, artworks, rugs, textiles.
In New Zealand, "architect" is a protected title, while designers offer creative direction once structure is in place.
