Architectural Designers

Architectural Designers near you

Most Australian houses are not designed by architects. They are designed by building designers, also called architectural designers or draftspeople, and on ordinary residential work that is an entirely normal and often sensible choice. What is not normal is how differently the states treat them. There is no national licence for building design, and the answer to whether your designer needs one depends on which side of a state line the job sits.

Queensland licences the work directly. The Queensland Building and Construction Commission issues building design licences in low rise, medium rise and open classes, alongside a hydraulic services design licence. The low rise class allows the holder to prepare plans and specifications for a class 1 or class 10 building, and for class 2 to 9 buildings with a gross floor area of not more than 2000 square metres excluding Type A and Type B construction, plus contract administration for building work the licensee designed. Applicants must show two years of relevant experience and hold professional indemnity insurance.

Victoria comes at it from the opposite direction. It does not licence building design as a trade in the Queensland sense, but the Architects Registration Board of Victoria says the Architects Act 1991 regulates the terms architectural services, architectural design services and architectural design, and only individuals and bodies registered or approved by the board may use them. So a Victorian building designer may lawfully design your house and may not lawfully advertise it as architectural design. That distinction catches out designers who cross borders, and it catches out homeowners reading websites.

Queensland licences the work; Victoria licences the words

In Queensland, preparing plans and specifications for residential building work is licensed activity, and the QBCC sets the scope by building class and floor area rather than by title. The low rise building design licence covers class 1 and class 10 buildings — which is to say houses, attached dwellings and the sheds, garages and carports that go with them — and extends into class 2 to 9 buildings under a floor area cap and outside the heavier construction types. Medium rise and open licences widen that scope. Because the scope is drawn by class, the question to ask a Queensland designer is not whether they are licensed but whether their class covers what you are building.

In Victoria the constraint is linguistic and it is enforced by a different regulator entirely. The ARBV's position is that the Act prohibits holding out as an architect or as providing architectural services, and that the regulated terms include architectural design. A designer who describes their service that way in Victoria is exposed regardless of how good the design is.

In other states the arrangement is different again, and in several of them building design for a house is not separately licensed at all. Do not generalise from one state's website to another. Ask the designer which state regulator they answer to for the job in front of you.

Architect, building designer, draftsperson: what the three words buy

  • An architect holds a protected title granted by a state or territory board and assessed against the National Standard of Competency for Architects held by the AACA.
  • A building designer may hold a state licence with a defined scope, as in Queensland, or may hold no licence at all, depending on where the work is.
  • A draftsperson usually describes someone documenting a design rather than originating it, which is a real and useful service but a narrower one.
  • Only the architect's title is protected nationwide; the other two words carry no automatic assurance and can be used by anybody in most of the country.
  • Professional indemnity insurance is the check that travels across all three, and in Queensland it is a licence condition for the design classes rather than an optional extra.
  • None of the three is a substitute for the person who actually issues your approval, who is a separate regulated role again.

What a building design service actually produces

  • A measured survey of what is there, which on an older house is more work and more value than people expect.
  • Sketch options that test the site, the orientation and the planning controls before anything is committed.
  • A developed design resolved far enough to support the planning or development application your council requires.
  • A working drawing set with enough detail for a building surveyor or certifier to assess and for a builder to price.
  • Coordination of the consultants the approval will need, typically an engineer and an energy assessor.
  • Responses to the questions that come back from the council and from the certifier, which is a real stage of the job and should be in the fee.
  • Contract administration during construction, which in Queensland is expressly within the low rise design licence for work the licensee designed.

Professional indemnity insurance is the substitute for a missing title

Where the state does not licence the designer, the insurance is doing most of the work of protecting you. A design error in a house is usually discovered during construction or, worse, afterwards, and the cost of fixing it lands somewhere. Professional indemnity cover is the mechanism that puts it somewhere other than your own pocket.

Queensland treats this as fundamental rather than optional. The QBCC requires applicants for a building design licence to demonstrate professional indemnity insurance, accepting a certificate of currency, a statutory declaration of compliance with the minimum standards, or a broker's receipt confirming the premium has been paid. That is a useful benchmark to apply even where you are not in Queensland: ask for the certificate, check the date, and check the cover is for design services.

Then read what the appointment says about who carries the risk if the design has to change after approval. A designer who takes responsibility for resubmission is worth more than one whose fee proposal quietly makes every council comment a variation.

Borders, websites and the claims that do not travel

Designers advertise nationally and build locally, which is where trouble starts. A page that describes a practice as offering architectural design is lawful in some places and prohibited in Victoria, where the ARBV says that phrase is one of the regulated terms. A Queensland licence number means nothing about a New South Wales job. A portfolio of Perth work says little about a Brisbane certifier's expectations.

There is also a scope trap inside a single state. In Queensland the licence classes are drawn by building class and floor area, so a designer licensed for low rise cannot simply take on work outside that class because they feel capable of it. Ask which class the licence is, then ask which class your building is.

The useful habit is to treat every regulatory claim as local until proved otherwise. Where the designer answers to a regulator, ask for the licence number and check it on that regulator's own register rather than on the designer's website.

The failure patterns specific to unregulated design

  • Drawings that are beautiful at planning stage and thin at construction stage, so the builder prices assumptions rather than a design.
  • No engineer engaged until after the layout is fixed, which turns a beam into a bulkhead nobody wanted.
  • An energy assessment treated as a rubber stamp at the end instead of a design input, so glazing has to be cut after the elevations are settled.
  • A designer working outside their licensed class in a state that licenses design by class.
  • No written scope for council responses, so the first request for further information becomes an argument about fees.
  • Marketing language borrowed from another state, which is both a compliance problem and a sign the practice has not read its own regulator.

Architectural Designers: frequently asked questions

Does a building designer need a licence in Australia?

It depends entirely on the state. Queensland licences building design through the QBCC in low rise, medium rise and open classes, with the low rise class covering plans and specifications for class 1 and class 10 buildings and for class 2 to 9 buildings under a floor area cap. Other states take different approaches, and in several of them designing a house is not separately licensed. Because there is no national licence, the only reliable answer is the one from the regulator in the state where the building will be built.

Can a building designer in Victoria call their work architectural design?

No. The Architects Registration Board of Victoria states that the Architects Act 1991 regulates the terms architect, architectural services, architectural design services and architectural design, and that only individuals and bodies registered or approved by the board may represent themselves that way. A designer who is not registered may still design buildings in Victoria; they may not describe the service using those words. If a Victorian website uses them, check whether the practice is actually on the ARBV's list.

What does a Queensland low rise building design licence let someone do?

The QBCC describes the scope as preparing plans and specifications for a class 1 or class 10 building, preparing plans and specifications for class 2 to 9 buildings with a gross floor area of not more than 2000 square metres but not including Type A or Type B construction, and contract administration in relation to building work designed by the licensee. Applicants must demonstrate two years of relevant experience, hold professional indemnity insurance, and meet the technical qualifications the QBCC publishes for licensing.

Is a building designer cheaper than an architect?

Usually, and for a conventional project in a straightforward planning context that difference is often good value. The saving disappears when the project is genuinely difficult, because unresolved design problems get paid for later by the builder rather than earlier by the designer. Judge it by the nature of your project: if the hard part is getting a well-documented set of drawings for a familiar building type, a licensed designer is efficient. If the hard part is working out what to build at all, design skill is the thing you are buying.

What should I ask a designer before engaging them?

Ask which regulator they answer to for a job in your state and for the licence number if there is one, then check it on the regulator's register rather than their website. Ask for a current certificate of professional indemnity insurance and confirm it covers design services. Ask what the fee includes at each stage, specifically whether responses to council requests and to certifier queries are inside the fee or charged as variations. Finally, ask to see a full working drawing set from a completed house, not just the renders.

What affects the cost of home design

Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:

  • Type of professional and service needed
  • Size and complexity of the project
  • Level of detail in drawings or reports
  • Number of site visits and meetings
  • Number of design revisions
  • Help with permits or contractor selection

How to compare architectural designers before you hire

  • Match the professional to the job: an architect or engineer where the work requires one, a designer for layout and finishes, or an inspector for a condition report.
  • Ask whether they are licensed or certified for this type of work in your area, where that applies.
  • Review a portfolio or sample report that's similar to your project.
  • Get a written agreement that spells out the services, deliverables, number of revisions and how fees are charged.
  • Ask whether their drawings will be suitable for a permit application, and whether they'll help with it.

Questions to ask architectural designers before you hire

  • Are you licensed or certified for this type of work in my area?
  • What exactly will you deliver: drawings, specifications, a report or site visits?
  • How are your fees charged: a fixed fee, hourly or based on the project cost?
  • How many rounds of revisions are included?
  • Will your drawings be ready for a permit application, and will you submit it?
  • Can I see a sample of a similar project or report?
  • Do you carry professional liability insurance?

When to call a pro for home design

  • Before removing or moving a wall that may be load-bearing
  • Before buying a home, to understand its condition
  • When a permit application needs drawings

Home design permits and local rules

Some home design work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
