Interior Design Fees in Melbourne: What Should You Actually Expect to Pay?
Let’s be honest.
Interior design fees can feel vague, mysterious… occasionally whispered about like they’re classified information.
If you’re renovating or building in Melbourne, you deserve clarity. Not fluff. Not “it depends” with no context. So here’s a grounded, real-world guide to what interior design typically costs and what you’re actually paying for.
Our beautiful Myrtle House project benefitted from a strong core team of interior designer, builder and cabinet maker - all committed to a successful project.
How Interior Designers Structure Their Fees:
In Melbourne, most designers use one (or a combination) of the following:
Hourly rate - generally $120–$250+ per hour
Fixed design fee - tailored to scope and size
Percentage of project cost - typically 8 to 15%
Procurement margin - applied to furniture, fixtures and finishes
The right structure depends on the project type and how involved the designer is from start to finish.
What Do Design Fees Look Like in Real Terms?
Here are realistic ballparks for Melbourne-based residential projects.
1. Bathroom Renovation
Build cost: $30,000–$60,000+
Design fees: $4,000–$8,000
This usually covers:
Concept design, spatial planning, 3D renders
Tile, stone and fixture selections
Joinery design
Design documentation for trades
Site visits during construction
Bathrooms are small but complex. Waterproofing, levels, lighting, storage - everything matters. Good design here prevents very expensive mistakes.
2. Kitchen Renovation
Build cost: $50,000–$120,000+
Design fees: $7,000–$20,000+
Kitchens require serious planning:
Layout optimisation
Custom cabinetry design
Appliance integration
Lighting and electrical planning
Concept direction and 3D renders
Detailed joinery documentation
This is where thoughtful design really pays off. Cabinetry errors alone can cost more than the design fee to fix.
3. Whole-Home Renovation or Extension
Build cost: $300,000–$1M+
Design fees: $25,000–$80,000+
This often includes:
Full concept development
Space planning
Interior and exterior finishes
Joinery design throughout
Lighting plans
Documentation packages
Builder liaison
Site visits during construction
For larger projects, fees may sit around 10–15% of the build cost, depending on involvement and level of service the client requires.
Why There’s Such a Range
Interior design isn’t just picking tiles.
Fees reflect:
Level of documentation required
Complexity of the build
Number of rooms
Structural coordination
Joinery detail
Construction support
Whether furniture and styling are included
A small cosmetic refresh is very different to designing bespoke cabinetry across an entire home.
What You’re Really Paying For
A good designer will:
Protect your budget
Refine your ideas into something cohesive and long lasting
Prevent costly on-site decisions
Reduce stress
Elevate the overall result providing you with a home that elevates how you live
If you’re time-poor and juggling work, family and everything in between, having someone take control of the process is often the biggest value of all.
A Final Word on “Is It Worth It?”
Design fees are typically a small percentage of the overall project cost, but they influence 100% of the outcome.
The right design decisions increase functionality, improve resale value, and make your home genuinely enjoyable to live in.
And that’s not a line item you can measure purely in dollars.
If you're planning a renovation in Melbourne and want clarity on what your specific project might involve, a tailored scope conversation is always the best first step. Every home is different and the right design support should feel considered, not cookie-cutter.
Interior design planning creates a seamless experience onsite in these critical rooms.
If you’re ready for someone to take control of the process and guide you through it properly — you know where to find me.
