Choosing the right building designer is one of the most important decisions you’ll make in your building project. The designer you choose will shape how your home looks, how it functions, how much it costs to build, and how smoothly the approval process goes. This guide covers what to look for, what questions to ask, and what red flags to watch out for.
In Queensland, anyone providing building design services must hold a QBCC (Queensland Building and Construction Commission) licence in the appropriate class. For residential building design, this is typically a Building Design — Open or Building Design — Medium Rise licence.
You can verify a designer’s licence on the QBCC website. If they can’t provide a licence number, walk away.
A building designer’s QBCC licence is your baseline assurance that they have the required qualifications and experience to design residential buildings in Queensland. Without it, they cannot legally sign off on plans for building approval.
Every building designer has a style and a strength. Some specialise in modern contemporary homes, others in traditional Queenslanders, and others in renovations and extensions. Before you engage a designer, look at their completed work and ask yourself:
A portfolio of impressive 3D renders is good, but photos of completed builds are better. Renders can make anything look amazing — the real test is whether the built result matches the vision.
Google reviews, Houzz reviews, and word-of-mouth referrals give you insight into what it’s actually like to work with a designer. Look for patterns in the reviews:
Good signs:
Warning signs:
A designer with 5-star reviews from both homeowners AND builders is a strong indicator of quality. Builders who recommend a designer are telling you that the plans were good enough to build from — and that’s the ultimate test.
Building design is not one-size-fits-all. A designer who excels at new custom homes on flat blocks may not be the best choice for a complex renovation of a 1970s split-level on a steep slope.
Ask specifically:
A designer who has worked on projects similar to yours will anticipate problems, know the approval requirements, and design more efficiently — saving you time and money.
Building design fees vary significantly on the Gold Coast — from $3,000 to $20,000+ depending on the project. For detailed pricing information, see our guide to building designer costs. But comparing fees alone is misleading if the scope of service differs.
Ask every designer you’re considering:
Get the fee proposal in writing before you commit. A professional designer will provide a clear proposal outlining the scope, deliverables, timeline, and payment schedule.
This is the factor most homeowners overlook, and it’s arguably the most important. Read our detailed article on what a licensed builder knows that a draftsman doesn’t.
A building designer who also understands construction — how buildings are actually built, what materials cost, how different details affect build time and cost — will produce plans that work in the real world.
Signs of construction knowledge:
Why this matters:
Plans designed without construction knowledge often look great but cost more to build than expected. The design may include details that are expensive or impractical, specifications that are vague, or dimensions that don’t work with standard material sizes. The result is builder variations, cost blowouts, and frustration.
A designer with real construction experience designs homes that builders can accurately price and efficiently build. That translates directly to fewer surprises, fewer variations, and a more predictable budget.
Your initial consultation is as much about assessing the designer as it is about discussing your project. Here are the questions that will tell you the most:
Non-negotiable. If they can’t provide a valid QBCC Building Design licence number, they cannot legally design your home in Queensland.
A professional designer provides a clear, written proposal before work begins. Verbal agreements lead to disputes.
If a designer avoids talking about construction costs or says “let’s design it first and then see what it costs,” they may not have the construction knowledge to design to a budget.
A quality design takes time. If a designer promises full plans in 2 weeks for a custom home, the documentation quality will likely suffer.
Professional indemnity insurance protects you if there’s an error in the design. Ask to see their certificate of currency.
A confident designer will happily connect you with past clients. If they won’t, ask why.
Getting 2-3 quotes is sensible, but don’t make price the only factor. The cheapest quote often comes with the least documentation, the fewest revisions, and the least council management — all of which cost you more in the long run.
Compare quotes on:
The right designer for your project is the one who understands your brief, works within your budget, communicates clearly, and produces documentation that builders can build from. Price is part of the equation, but it’s not the whole picture.
For most residential projects on the Gold Coast, a building designer offers equivalent design and documentation quality at 40-60% lower cost. Architects are better suited to complex commercial projects or highly conceptual design work. Read our full comparison guide: Building Designer vs Architect on the Gold Coast.
Technically yes, but a local designer offers significant advantages. They know Gold Coast City Council requirements, local builder capabilities, regional climate considerations, and site-specific challenges. Council processes and requirements vary between regions, and a designer familiar with your local council will navigate the process more efficiently.
Most designers can review and modify existing plans. However, if the plans need significant changes, it may be more cost-effective to start fresh. Bring your existing plans to the consultation and get an honest assessment.
For a standard custom home: 8-12 weeks from initial consultation to council-ready documentation. For a renovation or extension: 6-8 weeks. Complex or large-scale projects may take longer. Your designer should provide a timeline estimate during the consultation.
A building designer holds a QBCC licence and takes design responsibility for the project. A draftsman produces drawings under the direction of a licensed professional. When choosing someone for your project, always verify they hold a QBCC Building Design licence — not just drafting capability.
Choosing a building designer on the Gold Coast comes down to five key factors: valid QBCC licence, relevant experience with your project type, construction knowledge, clear and complete fee proposal, and strong reviews from both clients and builders.
Take the time to meet 2-3 designers, ask the right questions, and compare their proposals properly. The designer you choose will be your partner for months — and the quality of their work directly affects the cost, timeline, and outcome of your entire project.
