How much does an interior designer cost in Australia?

This guide gives the more useful version: what the published figures actually say, the four ways studios charge and where each one fits, the specific things that move a quote up or down, and the argument for when a designer costs less than not having one.

Luxxe Interiors is a Gold Coast interior design studio led by Tammy Brazel, who holds a Bachelor's Degree in Design and has worked in residential interiors for eight years. The studio has designed whole homes, kitchens and major renovations since 2019.

Fee secrecy serves studios rather than clients. It lets a quote arrive with no reference point, at the moment you are least able to judge it. You should walk into any first meeting, with us or anyone else, already knowing roughly what the numbers look like.

Key takeaways

The published numbers, with sources

Start with the figures that exist in print. Airtasker's Australian cost guide puts interior designers at $100 to $300 per hour. Its Queensland range is lower, at $80 to $250. The same guide puts whole-home design at $5,000 to $20,000. It gives a range of $90,000 to $250,000 for a large luxury home carried from first idea to finish.

Treat those numbers as a map rather than a quote. Directory averages fold together every kind of engagement, from a two hour colour consultation to a year of documentation and procurement on a new build. A designer charging $150 an hour who needs 300 hours costs more than one charging $250 who needs 150. The hourly rate tells you almost nothing on its own. The scope tells you nearly everything.

Why do so few studios publish their fees? Competition is one reason, but the main one is that a sound quote needs a clear scope: one family bathroom is not the same job as a three storey new build, and a public rate card would mislead one of those clients. A good studio will still explain its fee model in the first talk and put the final figure in writing.

Keep the design fee apart from the wider project budget, because the two are often confused. The fee pays for thought, drawings, choices and team care. Stone, joinery, furniture and labour sit in a much larger pool, and you will spend that pool with or without a designer. Judge an hourly advice rate on the time used, and judge a full fee against the money and risk it helps control.

Four fee models, and where each one fits

Australian residential designers generally price one of four ways, and each model suits a different kind of project.

Hourly rates suit advice. They work for a first visit, a plan review or a second view on a poor layout. You pay for time and can stop when you have what you need. The flaw appears on long jobs, where clients may hold back key questions to keep the clock down. That is a poor way to design a home.

Fixed fees suit a clear home brief. The designer reads the plans, sees the site and works out the likely hours. You then get one figure for a set scope and clear stages, which gives you cost certainty, and the studio takes the risk if the work runs slowly. The fee is only as sound as the scope behind it, though. A fixed quote given before anyone sees the home is still a guess.

Percentage fees link the design fee to the build or furniture budget. They appear most on large jobs where the designer helps run the whole build. A bigger budget often means more choices and team care, so the model can scale well. It also has a clear tension. If the fee rises with the budget, there is less reward for finding a cheaper item that works just as well.

Cost plus buying is the quietest model. The designer buys at trade prices and adds a margin to your bill. The design fee can then look low because some income sits in each order. There is nothing wrong with this when it is clear. Ask two questions. Is there a margin on buying? Do trade discounts come back to you or stay with the studio? Get both answers in writing before you sign.

Each fee model should answer the same questions before you commit. What do you get at each stage? How many rounds of change are in the fee? What happens when they run out? Does the figure include GST? Check what is left out too. Extra site visits, more drawings and buying time are common add-ons. A clear written answer also tells you how the rest of the job may run.

What moves a quote up or down

Two homes of the same size can produce design fees that differ by a factor of ten. These are the variables doing the work.

• Scope is the big one. Advice costs least. Drawings cost more. Full service costs most because the studio also buys, installs and helps on site.
• Drawing depth. A mood board may take an afternoon. Joinery, stone and power plans can take weeks. That detail raises the fee but cuts costly site changes.
• Structural change. Moving walls, wet areas or services brings drafting, compliance and coordination with builders and engineers into the fee.
• The number of spaces. One main idea can carry through a whole home. Even so, each new room adds real hours.
• Procurement and installation. If the studio orders, tracks, receives and installs hundreds of items, that logistics labour sits in the fee.
• The house itself. A vast Sovereign Islands home holds far more choices than a small Broadbeach flat. The fee follows that choice count.
• You. A client who makes clear choices costs less to serve. Reopening the kitchen plan in month four uses more rounds and adds work.

What the fee buys

A design fee makes more sense once you see what sits behind it. Full service starts with the main idea and room plans, then moves to materials and finishes, where each tile, tap, handle, light and fabric is named and coded so there is no doubt about what gets ordered. The fee also covers drawings for the builder and joiner, and it can include supplier care while goods are in flight and styling at the end.

One-room jobs follow the same logic at a smaller scale. Kitchens, baths and laundries need deep drawings for their size, because much of the room is fixed, plumbed or wired and a mistake can end up sealed under stone or waterproofing. A cinema or bar has a different load, with sound, light and joinery doing most of the work. A small bath can therefore cost more to design than a large lounge.

At Luxxe Interiors, our services have three tiers. Interior architecture covers plans, materials, joinery and light. Full service runs from the first idea to buying and install. Furniture and styling completes the final layer. Each job moves through Discover, Define, Create and Complete. You always know which stage the fee is funding.

3D views and a VR walk sit inside that process, and they matter to the fee more than they first seem. A change costs almost nothing on screen and thousands after stone is cut or joinery is built. A client who moves the island while walking through the future kitchen can stop a costly error before it reaches the site.

When a designer pays for themselves

Australians spend serious money on their homes. The Australian Bureau of Statistics counted $1.32 billion of residential alterations approved in June 2026 alone. Against budgets of that scale, a design fee can guard everything else you are about to spend. It pays back in three main ways.

The first is errors prevented, and this is the big one. Most renovation blowouts are not caused by champagne taste; they are caused by changes made on site, under time pressure, by people who are not the client. A waste lands 90 millimetres off the vanity centre and the whole cabinet is redrawn. A bench is measured before the appliances are confirmed. A tile order comes up two boxes short with a twelve-week lead time, and the job stops. Every one of those is cheap to fix on a drawing and expensive to fix in a house.

The second is trade access. Designers buy furniture, lighting, tile and fabric through trade-only suppliers, often at trade prices, and on a large furniture order the difference can cover a meaningful share of the fee. How much of that saving actually reaches you varies enormously between studios, so ask the question directly and get the answer in writing before you engage anyone.

The third is where the money lands. A Houzz & Home Australia study put the median kitchen renovation spend at $30,000, with 94 per cent of owners using professionals. On a budget that size, $3,000 spent on a finish you stop noticing within a month is money you cannot spend again on the bench you put your hands on every morning. Part of a designer's job is to make that trade on purpose.

None of this makes a designer free. It makes the fee a controllable, quoted number set against the least controllable numbers in the project.

Where the money goes in a full home

Square metres matter less than three things: the joinery you commission, where your furniture comes from, and how much of the house you take on at once. Roughly a third of a furnishing budget lands in the rooms you sit in: sofas, dining, rugs and beds. Joinery is the quiet second. Wardrobes, kitchens and wall panelling get built once and then carried for decades, so they repay what is spent on them. The rest spreads across lighting, window treatments, art and the hundred small objects that make a home feel collected.

Money disappears when decisions get made twice. A sofa ordered before anyone tested it against the room's scale, a palette chosen under showroom lighting and repainted a month later, freight nobody costed on an oversized piece. Much of a design fee is insurance against paying for the same thing twice. On a well-run project the fee tends to return itself: trade pricing covers part of it, avoided mistakes cover more, and the rest shows up as a home you are not correcting three years later.

How Luxxe Interiors quotes

We do not publish a price list because no two briefs are the same size. We can still explain the shape of the process.

It starts with a consultation. Tammy walks through the home or plans with you. She takes the brief and asks what will shape the work. Which spaces are in scope? How much detail will the builder need? Do you want buying and styling too? You then receive a written proposal. It sets a fixed fee, a clear scope and staged results. The fee is settled before design begins. If you add rooms or services later, the new fee is agreed in writing first.

The studio works from the Gold Coast. Many large briefs sit along the water in areas such as Sovereign Islands and Paradise Waters. There is work in Brisbane and interstate too. The portfolio includes four Sovereign Islands homes. Some exceed 4,000 square metres of internal floor area and $20 million in value. Luxxe Interiors also designed the interiors of Duddingston Guest House in Edinburgh, a Category A listed Palladian house designed by Sir William Chambers in the 1760s. Each of those projects needs its own fee discussion, which is why Luxxe Interiors scopes a quote for each one instead of handing you a rate card.

If you are weighing up a project and want a fee that reflects your actual scope, book a consultation and we will scope it properly.
