What does an interior designer cost in Melbourne?

The honest short answer is "it depends", but it depends on things you can pin down. The biggest factors are how much of the house is changing, how much drawing your builder will need, and whether the designer is also buying and installing furniture for you. Once you know those three things, quotes become much easier to read.

The three ways designers charge

Most Melbourne studios use one of three models, and many mix them: a fixed fee for the design stages and an hourly rate for open-ended work like site visits.

• Hourly. Published Melbourne rates mostly fall between about $120 and $300+ an hour, depending on seniority. One 2026 analysis of Australian quotes put the Melbourne average at around $210 an hour. Hourly is fair for small or uncertain jobs, but hard to budget for.
• Fixed fee per stage. The designer scopes the work after a consultation and quotes a set amount for each stage: concept, documentation and so on. Published Melbourne examples range from about $3,500 for a single zone to $20,000+ for larger projects. This is the easiest model to compare and to budget for.
• Percentage of project cost. Common on large renovations and new builds. Typical figures are 10% to 20% of the construction and furnishing budget, sometimes more for very involved projects. It scales with the job, but your designer’s fee rises as your budget does, so ask how it’s calculated.

What the first meeting costs

Many designers offer a free phone call first, then charge for an in-home consultation, usually 60 to 120 minutes with ideas on the spot and sometimes a written summary afterwards. One Melbourne studio publishes a price of $440 for a 90-minute visit, and a few hundred dollars is typical. Many studios credit that fee to the design work if you go ahead.

A paid consultation is worth it even if you don’t hire that designer. You get a professional’s eye on your rooms, a sense of what’s realistic, and a feel for whether you’d enjoy working together for a year.

The bigger number: what the work itself costs

Design fees are only part of the budget. Melbourne renovation cost guides published in 2025 and 2026 give a useful sense of scale:

• Kitchens. Mid-range renovations are mostly quoted between about $30,000 and $65,000, with premium joinery, natural stone or a new layout taking them well past that. A cosmetic refresh (new doors, benchtop and paint) can come in under $20,000.
• Bathrooms. One Melbourne guide updated in mid-2026 puts a mid-range bathroom at roughly $21,000 to $37,000, and notes ensuites tend to cost 20–30% less than main bathrooms. Layout changes and waterproofing are the big cost drivers.
• Whole-house renovations vary far too much to average. They depend on structure, services, heritage controls and how much of the house is touched.

What moves the number up or down

• How much is drawn. A builder-ready drawing set takes far longer than a concept and a shopping list, and it’s also what prevents expensive variations later.
• Joinery. Custom cabinetry is drawing-heavy. A house full of built-ins costs more to design than one furnished with loose pieces.
• Heritage and permits. Period homes in a Heritage Overlay may need extra coordination with your architect and council, mostly for external work.
• Procurement. Ordering, tracking and receiving furniture is real work. Some designers charge a fee for it and some take a margin on what they buy. Ask which.
• Revisions and site visits. Know how many are included and what extras cost.

Where a designer can save you money

A good designer won’t make a renovation cheap, but they can stop it getting expensive. The savings usually come from three places: avoiding mistakes that are costly to undo (a kitchen island that blocks a walkway, a vanity too deep for the room), giving builders a complete drawing set so quotes compare like for like, and making decisions early so trades aren’t waiting on you mid-build, when every day costs money.

The cheapest changes are the ones made on paper. The most expensive are the ones made after the tiler has gone home.

How to compare quotes

1. Line up the scope first: rooms, drawings, revisions and site visits.
2. Check how furniture is charged: a fixed fee, an hourly rate or a margin on purchases.
3. Ask whether the fee includes GST and what disbursements (printing, travel, samples) are extra.
4. Ask what happens if the scope changes, and how variations are priced.
5. Look at a drawing set from a past project, not just the photos.

If you’re still not sure, a paid consultation with two studios will tell you more than a dozen free quotes. You’ll learn how each one thinks, and the right fit is usually obvious by the end of the visit.
