Architects in Australia charge an average of 11.5% of the total construction cost for a full-service project (excluding GST). On a $600,000 new home build, that's around $69,000. For plans only, expect to pay around 6% of your build cost, or about $36,000 for the same project. Based on Bark's analysis of over 570 architect quotes across Australia in 2026.

The challenge is that not every project pays the same rate. Standard new builds typically sit around the 11.5% mark. Renovations and complex inner-city projects in Sydney and Melbourne can push fees toward 20% due to heritage overlays, strict council requirements and thermal performance mandates.

Learn exactly what you’ll pay for a new build, renovation, plans-only service or hourly consultation, so you enter architect meetings knowing a fair quote.

How much do architects charge in Australia?

The national average hourly rate for an architect is $175 per hour, based on January 2026 market data. However, Bark's 2026 quote data shows high-demand metros like Victoria and New South Wales averaging $180 per hour for hourly consultations.

For most residential projects, architects don't bill by the hour. They prefer a percentage of your total construction cost, which scales with the project and aligns their incentive with getting the build right.

Bark's analysis of over 570 architect quotes in 2026 shows the typical starting point at around $2,900 for basic architectural services. Premium or complex projects can reach $15,000 or more.

How much should I budget for an architect?

The average cost to build a standard detached house in Australia has risen to approximately $510,000 as of early 2026.

Typical project costs for a standard 200sqm home now range between $1,600 and $3,200 per square metre for mid-range finishes. For high-end architectural builds in metro areas like Sydney or Melbourne, these figures often start at $4,000 per sqm.

A project on a site with no planning overlays or complex easements typically attracts 9% of the build cost. On a current average build of $510,000, this equates to roughly $45,900.

Inner-city projects featuring limited site access, heritage overlays, or strict Bushfire Attack Level (BAL) and flood requirements now push fees toward 12% to 20%. For that same average build, these complex projects can see professional fees that may exceed $100,000.

Note that these fee estimates cover the architect's fee only. Structural engineering and thermal assessments are usually quoted separately and average around $8,500 extra.

How much does it cost to get an architect to draw plans?

If you only need plans and aren't engaging an architect for the full build management process, the average cost is 6% of your construction budget. On a $600,000 project, that's around $36,000.

For a $1,000,000 build, plans alone are estimated to cost around $60,000. This typically doesn't include structural engineering or a thermal assessment, which adds an average of $8,500 on top.

For renovation projects, costs are more fixed and easier to predict upfront. Small renovation plans average $4,000. Medium renovation plans for a $300,000 project average around $15,000 for a master plan or $30,000 for full documentation.

How much does an architect charge for a renovation vs a new build?

Renovations consistently attract higher architect fees than new builds, typically 2% to 3% points more. A new home on a standard suburban block might attract a fee of up to 9%. The same budget spent renovating an inner-city terrace in Sydney or Melbourne typically attracts a 13.5% fee.

The reason is straightforward. Existing structures involve more unknowns. Architects spend more time on site visits, structural assessments, heritage documentation and council correspondence than they would on a blank-slate new build.

A simple new home on a standard site attracts fees of around 7% of the build cost. For complex circumstances such as renovations, heritage overlays or inner-city constraints, this rises to around 15%. If your project is in a heritage zone or inner-city suburb, budget for the upper end of that range.

Does your location affect what you pay an architect in Australia?

At a national level, architect fees are a percentage of construction cost, so location matters mainly because it affects your build budget. Altus Group's Q4 2025 Australian construction price outlook forecasts 2026 build cost escalation at 4.5% in Sydney, 7.5% in Brisbane and 4% in Melbourne. A higher build cost means a higher architect fee in dollar terms, even if the percentage stays the same.

At an hourly rate level, Bark's 2026 quote data shows both Victoria and New South Wales averaging $180 per hour for consultation. The national average sits at $175 per hour.

How do architects set their fees?

There's no standard fee guide in Australia. The Australian Institute of Architects (AIA) withdrew its fee schedule in 2005 following concerns from the ACCC about anti-competitive pricing. That gap has created real confusion for clients.

Getting at least three quotes from different practices is the only reliable way to calibrate what's fair for your specific project.

However, there are four main ways architects structure their fees.

• Percentage fees: The most common structure for full-service residential projects. The architect charges a percentage of your total construction cost, typically averaging 11.5% for a full service or 6% for plans only.
• Fixed fees: A set amount agreed at the start, usually for clearly defined scopes. Works well for plans-only commissions and specific project stages where the scope is settled upfront.
• Hourly fees: Used for initial consultations, advisory services or work that falls outside an agreed scope. The national average is $175 per hour.
• Square metre fees: Less common, but occasionally used for certain residential project types. Typical rates run around $1,400 per square metre for brick veneer and $1,490 per square metre for full brick construction.

What does the process involve when working with an architect?

Working with an architect on a full-service commission typically involves eight stages, as outlined by Archicentre Australia and Canstar.

Stage 1: Design consultation or feasibility study. 

The architect discusses your brief and budget and advises on what's achievable on your site. Some firms charge hourly for this stage.

Stage 2: Concept design. 

Sketch designs are developed, and a rough cost estimate is prepared. Site orientation, energy efficiency and planning overlays are assessed at this stage.

Stage 3: Design development. 

Drawings are refined, council requirements are checked and a detailed cost plan is prepared for all parties to sign off.

Stage 4: Development application (DA). 

Your architect prepares and lodges all documents required by your local council. Standard DA approvals typically take 6 to 12 weeks in most Australian states.

Stage 5: Construction documentation. 

Detailed working drawings and specifications are prepared so builders can quote accurately, and a building permit can be issued.

Stage 6: Contract selection (tendering). 

Your architect helps you shortlist and negotiate with builders.

Stage 7: Contract administration. 

The architect visits the site, approves payment claims, manages variations and resolves disputes.

Stage 8: Project completion. 

A practical completion inspection identifies any defects before the handover certificate is issued.

Not every client needs all eight stages. A plans-only engagement typically covers stages 1 to 5. Discuss with your architect upfront which stages you're commissioning, and get the scope of each in writing.

Post your project on Bark and get quotes from registered architects.

What can architects do to help build or renovate a home?

According to the Australian Institute of Architects (AIA), a registered architect can manage almost every part of your residential project from brief to handover.

The core services include:

• Preparing a design brief and concept design based on your budget and how you want to live in the space
• Lodging development applications and responding to council feedback throughout the approval process
• Applying for building permits through a private building surveyor
• Helping you find, compare and negotiate contracts with builders during the tendering stage
• Supervising the construction process, attending site meetings and managing contract variations
• Conducting a practical completion inspection to identify defects before handover

What separates a registered architect from a building designer or drafter is accountability and scope. 

Architects must be registered with their state or territory Architects Registration Board and hold professional indemnity insurance. They must also pass the Architects Practice Examination administered by the Architects Accreditation Council of Australia (AACA). They're qualified to manage complex projects with heritage overlays, difficult sites or multi-storey construction.

Is an architect more expensive than a building designer?

Yes, in most cases. Registered architects charge an average of $175 per hour, or 10% to 15% of construction costs for a full service. Building designers typically cost around 30% to 50% less, charging $90 to $180 per hour or 5% to 8% of the build cost.

The trade-off is scope and professional standing. A building designer can handle most standard residential projects and development applications. For projects with heritage restrictions, complex structural requirements or inner-city council constraints, an architect's registration and professional accountability may be essential rather than optional.

If your project is straightforward and your council doesn't impose strict design requirements, a building designer can deliver a quality result at a lower cost. If you're renovating a heritage home in Sydney's inner west or building on a difficult site in Melbourne, the additional cost of a registered architect is usually justified. If you need a structural engineer as well, that's typically quoted separately and averages around $8,500 for most residential projects.

What should I look for when choosing an architect in Australia?

We recommend checking four things before signing any agreement.

• Registration: Verify that your architect is registered with the Architects Registration Board in the state or territory where you plan to build. You can check registration through the relevant state board's website.
• A written agreement: Both parties should agree on the exact scope of services, fees, payment schedule and exit conditions before any work starts. Verbal agreements don't hold up when disputes arise.
• A transparent fee proposal: Ask for a written, stage-by-stage fee breakdown that includes all anticipated costs. Hidden fees are common in the industry, and upfront clarity saves significant pain later.
• Exit and variation clauses: Discuss how to pause or exit the agreement if your circumstances change. For large or long-running projects, this is essential rather than optional.

Before committing, meet at least two or three architects and ask each one to walk you through how they'd approach your specific project. If you're also budgeting for interior design or a property extension, get those quotes alongside your architect’s brief so you're working with one integrated budget.

Architect fees in Australia average 11.5% for a full service or 6% for plans only, based on your total construction budget. Your location and project type are the two biggest variables, with renovations and inner-city builds consistently sitting at the higher end.

When comparing quotes, check what each fee actually includes. A low percentage that excludes construction administration can cost more in the long run when hourly out-of-scope rates kick in.
