Interior Architect vs. Interior Designer: The Key Differences Explained

28 Sept

Written By MILEHAM

When it comes to transforming the homes we live in into beautiful, functional, and harmonious environments, two professions often come to mind: interior architects and interior designers. Although the terms for these professions are sometimes used interchangeably, they are distinct disciplines, each with their own unique focuses and skill sets.

Here, we delve into the key differences between interior architecture and interior design, shedding light on the roles they play in shaping the spaces we live in, to help you choose the right path for your home renovation project.

What do Interior Architects and Interior Designers do?

Interior Architects

Interior architecture is a specialised field that primarily deals with the structural aspects and spatial configuration of a home's interior. Interior architects (including architects more broadly) are responsible for optimising the layout of spaces to ensure functionality, safety, and compliance with Australia’s National Construction Code. Their work often involves altering or reconfiguring existing structures to accommodate the needs of the occupants.

Key responsibilities of interior architects include:

Space Planning: Interior architects carefully plan how spaces are organised within a structure. They consider traffic flow, furniture placement, and the efficient use of available space.
Structural Modifications: They may be involved in making structural changes, such as removing or adding walls, to create open-concept spaces or divide rooms according to a client's requirements.
Building Codes and Regulations: Interior architects must stay updated on, an incorporate, Australian building codes and regulations to ensure their designs meet safety and legal requirements.
Material Selection: They choose materials and finishes that align with the aesthetic and functional goals of the project while considering durability, sustainability, maintenance and building code.
Collaboration: Interior architects work closely with engineers and builders to ensure their designs are seamlessly integrated into the overall building plan.

Interior Designers

On the other hand, interior designers focuses on the aesthetics, atmosphere, and overall visual appeal of interior spaces. Interior designers are responsible for selecting colours, textures, furniture, lighting, and decor to create a cohesive and pleasing environment that reflects the client's personality and preferences.

Key responsibilities of interior designers include:

Concept Development: Interior designers collaborate with clients to understand their vision and preferences, translating them into a design concept that sets the tone for the project.
Colour and Material Selection: They choose paint colours, fabrics, flooring, and other materials that harmonise with the design concept and create a desired mood.
Furniture and Decor: Interior designers select furniture, fixtures, and decorative elements that enhance the overall aesthetic and functionality of a space.
Lighting Design: They plan the lighting layout to achieve the desired ambiance and functionality, considering natural and artificial lighting sources.
Project Coordination: They liaise with architects, builders and clients to ensure the design is implemented accurately and efficiently into the overall building plan.

Education and Training

In Australia, both interior architects and interior designers typically undergo formal education and training, however specific, legal training requirements apply for architects which are not required for interior designers.

Interior Architecture

The title “Architect” is protected by legislation in Australia, meaning it is illegal for a designer to call themselves an “Architect” (including “Interior Architect”) unless they have completed the qualifications, accreditation and registration as required by each State or Territory’s law. In NSW this is controlled by the NSW Architects Registration Board.

As such, an Interior Architect will have completed a Master of Architecture or Bachelor Degree of Interior Architecture, with a strong emphasis on the architectural aspects of the discipline. Their education includes coursework in building systems, construction technology, and structural design, all while considering Australian building standards and regulations. This knowledge equips them to handle the technical and structural aspects of interior spaces while complying with local requirements.

They will then also be required to undergo a certain amount of on-the-job work experience, and move through the requirements set by their State or Territory in order to attain their registration.

Interior Design

There are no required industry accreditations or licenses that enable one to work as an interior designer in Australia, however most interior designers have undertaken formal education and work experience. Certification through professional organisations such as the Design Institute of Australia can enhance an interior designer’s professional standing.

Formal interior design education focuses on colour theory, spatial design, furniture design, and interior decorating, all within the context of Australian design and safety standards. While interior designers may have some knowledge of building systems and codes, their primary expertise lies in creating aesthetically pleasing and functional interiors.

Collaboration between Interior Architects and Interior Designers

In many projects, interior architects and interior designers collaborate to create cohesive and well-balanced interior spaces. Their collaboration ensures that both the structural and aesthetic aspects of a design are addressed effectively. Here's how they typically work together:

Early Planning: Interior architects and interior designers often come together during the early planning stages of a project to establish the overall vision and layout.
Space Planning: Interior architects develop the initial floor plans, considering structural elements and Australian building codes, while interior designers provide input on how the space should function, feel and look.
Material Selection: Interior architects may select materials that meet structural requirements and Australian standards, and interior designers choose finishes and decor that align with the overall design concept.
Furniture Integration: Interior designers select furniture and furnishings that complement the architectural elements created by interior architects.
Lighting Design: Interior architects may plan the placement of lighting fixtures, and interior designers select fixtures that enhance the design concept.
Project Coordination: Throughout the project, both professionals coordinate with the builder, tradespeople, and the client to ensure the design is executed according to the brief.

So, which one is best for your home renovation project?

Interior architecture and interior design are distinct but complementary fields within the realm of creating beautiful and functional home interior spaces. While interior architects focus on the structural and spatial aspects of a space, interior designers concentrate on the aesthetics and atmosphere.

Which one is best suited for your home renovation project depends on the scope of your project. For example, if you are planning to knock down or push out walls as part of a major internal renovation, an interior architect is probably your best bet. However, if you are. simply looking to visually update the overall look of a room or interior space without changing any of the built structures within your home, then an interior designer is your best bet.
