What Does an Architect Cost in Melbourne?
A transparent breakdown of architectural fees by project type, what is included in an architect's service, and how to budget for your residential project.
Key takeaways
- Architectural fees in Melbourne typically range from 9% to 16% of construction cost, depending on project complexity and scope [1]
- A full architectural service covers far more than drawings, from initial site analysis and feasibility through to construction oversight and handover
- Comparing architects on fee percentage alone misses the point. The scope of service, design quality, and project management capability matter more
- An architect's involvement often reduces construction cost overruns and variations, which can offset the fee many times over [2]
- For smaller projects (under $200,000 construction cost), a lump sum or hourly fee arrangement is often more appropriate than a percentage
- Melbourne's planning requirements, particularly in heritage and character overlay areas, mean architectural expertise can save months of delays and rework
How architects typically charge in Melbourne
There are three main fee structures used by residential architects in Melbourne, and the right one depends on the scale and complexity of the project.
Percentage of construction cost is the most common model for projects above $200,000. The architect's fee is calculated as a percentage of the final construction budget. This model aligns the architect's scope with the project's scale, so a more complex or larger project naturally attracts a proportionate fee.
Lump sum is often used for clearly defined projects where the scope is predictable. Granny flats, simple renovations, and single room additions lend themselves to lump sum pricing because the amount of design and documentation work is relatively known from the outset.
Hourly rates suit projects that are hard to define upfront, such as feasibility studies, heritage consultations, or town planning advice where the scope depends on council feedback. In Melbourne, principal architect hourly rates typically range from $200 to $300 per hour (excluding GST), with junior architects and drafting staff at $100 to $160 per hour [1].
Most practices use a combination. A percentage fee for the core design and documentation stages, with hourly rates for town planning and construction administration, is a common and practical structure.
Fee ranges by project type
The table below shows indicative architectural fee ranges for residential projects in Melbourne. These figures are inclusive of GST and based on the Australian Institute of Architects fee guidelines for RAIA Classification II (complex residential) projects [1].
| Project Type | Construction Budget | Typical Fee Range | Indicative Fee Amount |
|---|---|---|---|
| Small renovation or addition | $150,000 to $300,000 | 13% to 16% | $19,500 to $48,000 |
| Medium renovation or new build | $300,000 to $600,000 | 11% to 13% | $33,000 to $78,000 |
| Large renovation or new home | $600,000 to $1,200,000 | 10% to 11% | $60,000 to $132,000 |
| High-end or complex new home | $1,200,000+ | 9% to 10% | $108,000+ |
| Granny flat or secondary dwelling | $120,000 to $250,000 | Lump sum | $15,000 to $35,000 |
| Duplex or multi-residential | $800,000 to $2,000,000+ | 9% to 12% | $72,000 to $240,000 |
These are guide ranges only. The actual fee depends on factors including site complexity, planning requirements, sustainability targets, and the level of interior design included. Every architect structures fees differently, so a direct comparison requires understanding what is and is not included.
A lower fee percentage does not always mean lower total cost. An architect who charges 10% but produces thorough documentation can save 5% to 10% in construction variations compared to one who charges 8% but leaves gaps in the drawings.

What is included in an architect's fee
A full architectural service in Melbourne typically covers six stages. Understanding these stages helps you see where the time and value sits.
Stage 1: Concept Design (approximately 15% of total fee)
The architect visits the site, analyses the opportunities and constraints, reviews planning controls, and develops initial design options. This is where the big ideas are explored, tested against the site, budget, and brief, and refined into a direction.
Stage 2: Design Development (approximately 20% of total fee)
The chosen concept is developed in detail. Room layouts, material selections, window positions, structural approaches, and sustainability strategies are resolved. By the end of this stage, you should have a clear picture of what the finished building will look and feel like.
Stage 3: Town Planning (varies, often hourly)
If a planning permit is required (and in Melbourne, it often is), the architect prepares or coordinates the planning application. This includes drawings, shadow diagrams, neighbourhood context analysis, and written design response. Town planning can be straightforward or complex depending on overlays, objections, and council requirements.
Stage 4: Construction Documentation (approximately 30% of total fee)
This is the most documentation intensive stage. The architect produces the detailed drawings and specifications that builders use to price and construct the project. Good documentation reduces ambiguity, limits variations during construction, and protects you contractually.
Stage 5: Contractor Selection (approximately 5% of total fee)
The architect helps you select a builder through a tender process or negotiated contract. This includes preparing tender documents, assessing submissions, checking references, and advising on contract terms.
Stage 6: Contract Administration (approximately 30% of total fee)
During construction, the architect reviews progress, assesses payment claims, manages variations, and ensures the work matches the documentation. This stage protects your investment and is where many of the costly mistakes are caught before they become expensive problems.
Architect vs building designer: understanding the difference
This is one of the most common questions homeowners in Melbourne ask, and the answer matters for both cost and outcome.
A registered architect holds a minimum five year university degree in architecture, has completed a structured practical experience programme, and passed the Architectural Practice Examination. They are registered with the Architects Registration Board of Victoria (ARBV) and are legally required to carry professional indemnity insurance. The title "architect" is protected by law in Australia [3].
A building designer (sometimes called a draftsperson) may have a diploma or advanced diploma qualification. They are registered with the Victorian Building Authority under the building practitioner registration scheme. Building designers can produce competent documentation for straightforward projects, and their fees are generally lower.
| Architect | Building Designer | |
|---|---|---|
| Qualification | 5+ year university degree | Diploma or advanced diploma |
| Registration | ARBV (Architects Act 1991) | VBA (Building Act 1993) |
| Professional indemnity insurance | Mandatory | Varies |
| Typical fee range | 9% to 16% | 4% to 8% |
| Design complexity | Complex, site-responsive design | Standard to moderate |
| Planning expertise | Strong, especially complex overlays | Varies |
| Contract administration | Full service available | Limited or not offered |
The choice depends on the project. For a straightforward single storey extension with no heritage overlays and a clear brief, a good building designer may deliver excellent value. For a project involving planning complexity, significant design ambition, heritage considerations, or multi-storey construction, an architect's training and expertise typically justify the higher fee.
How Melbourne's planning requirements affect cost
Melbourne's planning scheme is more complex than most Australian cities, and this directly affects architectural fees.
Properties in Heritage Overlay areas (common in suburbs like Brunswick, Northcote, Carlton, Fitzroy, Kew, and Hawthorn) require additional analysis, more detailed drawings, and often heritage consultant input. A heritage renovation can add 10% to 20% to the architectural fee compared to an equivalent project without heritage constraints [4].
Neighbourhood Character Overlay and Design and Development Overlay areas require specific design responses that demonstrate compliance with local policy. This means additional documentation and sometimes additional meetings with council planners.
Clause 55 (ResCode) applies to most residential development in Victoria and sets standards for setbacks, overlooking, overshadowing, and private open space. Meeting these standards requires careful analysis and sometimes creative design solutions that take additional time.
Projects requiring a planning permit typically add a town planning stage that can range from $3,000 to $15,000 depending on complexity, whether objections are received, and whether a VCAT hearing is required. Some straightforward permits are resolved in 8 to 12 weeks, while contested applications can take 6 to 12 months.
The practical implication is that homeowners in planning sensitive areas should budget for a higher architectural fee and a longer timeline. The architect's role in navigating these requirements efficiently can save significant time and cost compared to proceeding without expert guidance.

How to get the most value from your architect
Understanding a few practical principles can help you get better outcomes from your architectural investment.
Define your brief clearly. The more clearly you can describe how you want to live in the finished building, what matters most, and what your budget limits are, the more efficiently the architect can design. Ambiguity in the brief leads to more design iterations, which costs time and money.
Set a realistic budget. A common issue is a mismatch between expectations and budget. Be honest about your construction budget from the start. A good architect will tell you what is achievable within your budget rather than designing something you cannot afford to build.
Choose your builder wisely. The architect's documentation is only as valuable as the builder who executes it. Ask your architect for builder recommendations and take their advice on contractor selection seriously.
Do not skip contract administration. This is the stage most commonly dropped to save fees, and it is almost always a false economy. Without an architect reviewing progress and managing variations, the risk of cost overruns and quality issues increases substantially.
Engage early. Bringing an architect in at the feasibility stage, before you commit to purchasing a property or finalise a budget, gives you the best chance of a realistic, well-planned project.
What a recent Melbourne project looked like
To give a practical example, a recent renovation and addition project managed by Dadirri Architects involved converting an existing garage and laundry into a self-contained bed and breakfast suite, along with a new kitchen, bathrooms, and living area upgrades for the main residence.
The project included sustainable design features (solar power and battery storage for carbon neutral operation, rainwater harvesting), heritage sensitive material choices (exposed Meranti Maple hardwood to reference the original 1970s construction), and contemporary interior design. The architectural service covered concept design through to construction completion, including coordination of structural, services, and sustainability consultants.
For a project of this nature, the architectural fee would typically fall within the 11% to 14% range of the construction budget, covering all six service stages outlined above.
Frequently asked questions
Do I need an architect for a renovation in Melbourne?
Not always. For cosmetic renovations that do not involve structural changes or planning permits, a builder or interior designer may be sufficient. However, for projects involving structural alterations, additions, heritage properties, or planning permit applications, an architect's expertise adds significant value and can prevent costly mistakes.
How much does an architect cost for a house extension in Melbourne?
For a typical house extension with a construction budget of $300,000 to $500,000, expect architectural fees of 11% to 14% of the construction cost (including GST). This translates to approximately $33,000 to $70,000 for full architectural services from concept design through to construction completion.
Can I hire an architect for just the design stage?
Yes. Many architects offer partial services, such as concept design only, or design through to planning approval. This is sometimes called a "design only" engagement. The fee is adjusted to reflect the reduced scope. Be aware that documentation produced by another party after design handover may not fully capture the design intent.
Is an architect worth the cost compared to a building designer?
It depends on the project. For complex renovations, planning sensitive sites, multi-storey builds, or projects where design quality is a priority, an architect's additional training and expertise typically delivers better outcomes that justify the higher fee. For simple, straightforward projects on unconstrained sites, a competent building designer can provide good value.
How do I compare quotes from different architects?
Focus on what is included in the fee, not just the percentage. Ask each architect to clearly define their scope of service for each project stage, how they handle variations and additional work, what consultants are included or excluded, and whether the fee is inclusive of GST. A lower percentage with a narrower scope may end up costing more than a higher percentage with comprehensive service.
When should I engage an architect in the process?
As early as possible. Ideally, engage an architect before purchasing a property (for a feasibility assessment) or at the very start of project planning. Early engagement allows the architect to identify opportunities and constraints that can save significant time and money later. Engaging after plans have already been drawn by another party limits the architect's ability to add value.
Are architectural fees tax deductible?
Architectural fees for investment properties are generally tax deductible as a capital works deduction under Division 43 of the Income Tax Assessment Act 1997. For owner-occupied homes, architectural fees are not deductible but may be included in the cost base of the property for capital gains tax purposes. Consult your accountant for advice specific to your situation.
What happens if the project goes over budget?
A good architect monitors the project budget throughout the design process and provides cost estimates at key milestones. If the project exceeds the agreed budget, the architect works with you to identify savings through value engineering, material substitutions, or scope adjustments. The contract administration stage also helps manage costs during construction by reviewing and advising on variations before they are approved.
