If you’re planning a renovation, new build or interiors project, one of the first questions you might have is, how much does an interior designer cost? The answer depends on the scope of work, the size and complexity of your project, and the level of design guidance required.
A single-room furnishings and styling project is very different from designing a kitchen, bathroom or an entire home. Each involves different considerations, decisions, documentation and levels of support. Understanding what influences interior design fees can help you plan your budget, understand what you’re investing in and make informed decisions about the services you need.
What affects the cost of interior design
- Scope of work: Whether you need furnishings and styling for one room, a kitchen or bathroom design, lighting design, interior and exterior selections, or full-service interior design for a renovation or new build.
- Project size and complexity: The number of rooms, level of customisation, specialist finishes, appliances, fixtures and fittings, and the amount of detailed planning required all influence the scope. A highly customised kitchen may involve more detailed design work than several simpler rooms.
- Design documentation: Depending on your project, this may include floor plans, elevations, joinery details, lighting and electrical plans, material and finish schedules, fixture and fitting selections, and 3D visuals. This documentation helps communicate the design intent to your builder, trades and suppliers.
- Stage of the project: Involving an interior designer early provides more opportunity to resolve decisions before they are locked in. Changes made after documentation, quoting or construction has progressed may require additional design work.
- Ongoing design support: Supplier liaison, procurement support, agreed site visits and assistance with design queries may be included depending on your project requirements.
- Revisions and changes to scope: Additional revisions, new requirements or changes beyond the agreed scope can affect the overall design fee.
Common ways interior designers charge
Interior designers may structure their fees in different ways, depending on the project and the services provided.
Fixed fees
An agreed fee for a clearly defined scope of work and set of deliverables. This provides clarity around the design investment, with any additional work or changes outside the agreed scope discussed separately.
Hourly rate
An hourly rate may be used for smaller, clearly defined design tasks, additional consultations, revisions or work outside an existing agreement.
Staged fees
Design fees may also be structured around project stages, such as concept design, design development and documentation, with the deliverables and payment arrangements outlined in the proposal.
Regardless of the fee structure, it is important to understand what is included, what is excluded and how additional work will be managed before proceeding.
What is separate from interior design fees?
One important distinction is the difference between your interior design investment and your overall renovation, construction or furnishing budget. Interior design fees generally relate to the professional services, design development and agreed documentation required for your project.
Construction costs, trades, materials, fixtures, fittings, furniture and other products are typically separate from these fees. Depending on the scope of your project, procurement, additional revisions, travel and ongoing design support may also involve separate charges.
At JML Design, we outline the agreed inclusions, deliverables and applicable fees in your proposal, so you have a clear understanding of the investment before moving forward.
How thoughtful design planning can help avoid costly mistakes
Every project begins with a complimentary 20-minute discovery call to discuss your project, priorities, timeline and budget expectations.
The next step is a paid initial consultation of $495 including GST, for up to two hours, held in person where possible or via Zoom for remote projects. During this consultation, we explore your project in greater detail, understand your lifestyle, priorities and challenges, and gather the information needed to establish a clear design brief.
Following the consultation, we prepare a tailored scope of work and design fee proposal outlining the recommended design services, deliverables, process and investment. This provides clarity around the proposed scope and fees before you decide whether to proceed with the design engagement.
Additional travel charges may apply depending on your project location and will be discussed in advance.

Can I engage an interior designer for just one part of my project?
