If you’re planning a renovation on the Gold Coast, one of the first decisions you’ll face is whether to hire a building designer or a draftsman. They might sound like the same thing, but the difference can have a real impact on your project’s outcome — and your budget.
Here’s a practical breakdown so you can make the right call for your situation.
A draftsman (or drafter) produces technical drawings based on your instructions. You tell them what you want — knock out this wall, add a room here, extend the kitchen there — and they draw it up so it can be submitted for approval.
Draftsmen are typically best suited for straightforward projects where you already have a clear idea of what you want. Think simple room additions, carport conversions, or deck enclosures where the design decisions are fairly obvious.
It is worth noting that draftsmen in Queensland are not required to hold a QBCC licence or carry professional indemnity insurance. Many are skilled at what they do, but there is less regulatory accountability if something goes wrong with the documentation.
A building designer does everything a draftsman does — and quite a bit more. They bring design thinking to the table: spatial planning, natural light optimisation, material selection, energy performance, and how the renovation integrates with your existing home.
A good building designer will also consider things most homeowners don’t think about until it’s too late: structural load paths, cross-ventilation, acoustic separation between living zones, and how your renovation will interact with council overlays and building codes on the Gold Coast.
In Queensland, a licensed building designer holds a QBCC licence and carries professional indemnity insurance — meaning they’re accountable for the design they produce.
The QBCC licensing system has specific tiers that determine what a professional can and cannot design. A Building Designer — Open licence allows the holder to design any class of building with no monetary limit. A Building Designer — Medium Rise licence covers buildings up to three storeys, while a Low Rise licence covers single and two-storey residential work. Below these sits the Architectural Draftsperson licence, which permits the preparation of drawings but not the provision of design services in the same capacity. If you are considering a substantial renovation — particularly one involving structural changes or a second storey — you want someone whose licence covers that scope.
A draftsman can be the right choice when:
For these projects, a draftsman will usually cost less upfront, and that can make sense if the scope is genuinely simple. For an idea of typical fees across both options, see our guide on building designer costs on the Gold Coast.
For most Gold Coast renovations beyond the basics, a building designer is the smarter investment. You’ll want a designer when:
A building designer can often save you money overall by getting the design right before construction starts. Changes on paper cost next to nothing — changes on site cost thousands.
The Gold Coast presents specific challenges that make professional design input particularly valuable. Large parts of the city fall within flood overlay zones — particularly suburbs like Benowa, Merrimac, Mudgeeraba, and areas along the Nerang River. If your property sits within a flood overlay, your renovation must comply with minimum habitable floor levels and account for water flow paths. Getting this wrong does not just mean a council rejection — it can mean an uninsurable home.
Gold Coast City Plan also applies overlays beyond flooding. Bushfire hazard overlays affect properties backing onto hinterland vegetation. Landslide hazard overlays apply to steeper blocks in suburbs like Mudgeeraba, Tallai, and Bonogin. A building designer who works regularly on the Gold Coast understands how to navigate these overlays and design around them, rather than discovering constraints after you have committed to a layout that cannot be approved. They can also adjust a design to keep it within code-assessable thresholds under City Plan, saving you weeks of assessment time and thousands in planning fees.
| Building Designer | Draftsman | |
|---|---|---|
| Qualification | QBCC licensed (Building Designer — Open, Medium Rise, or Low Rise) | May hold QBCC Architectural Draftsperson licence; not always required |
| Typical Services | Design development, documentation, council coordination, consultant management | Drafting plans and documentation from client instructions |
| Design Input | Provides spatial planning, material advice, performance optimisation | Documents your decisions rather than providing design direction |
| Council Coordination | Manages planning overlays, code compliance, and approval strategy | Typically prepares drawings only; you or your builder handles council |
| Cost Range | Higher upfront but often reduces construction costs through better design | Lower upfront fees; potential for additional costs if design issues arise on site |
| Best For | Complex renovations, second storeys, challenging sites, homes where design quality matters | Simple projects with a clear scope and no site complications |
At Design Science, David Steadman holds both a Building Designer licence and an Open Builder’s licence under the QBCC. This dual qualification is rare on the Gold Coast and means your renovation is designed by someone who doesn’t just draw buildings — he builds them.
That practical building experience translates directly into better design outcomes: details that are buildable, specifications that builders can actually price accurately, and designs that anticipate construction challenges before they become costly problems.
To give a concrete example: a common Gold Coast renovation involves opening up the back of a 1980s brick home to create an indoor-outdoor living area. A designer without building experience might draw a large bi-fold door opening and specify a steel beam above it, leaving the structural details to the engineer and builder. A designer who has actually built these renovations knows the existing brick wall likely sits on a strip footing never designed for a point-loaded steel beam. That means the design needs new pad footings at each post location — and if those pads fall near existing stormwater lines or slab edges, the structural approach may need to change entirely. David’s builder knowledge means these issues are resolved at the design stage, not discovered mid-demolition when the builder is calling to say the original plan will not work. If you want to understand more about what this process looks like, read our guide on what to expect when working with a building designer.
Some builders offer “free design” or include a draftsman as part of their package. While this can seem like good value, it’s worth understanding what you’re getting. A builder’s draftsman typically works to the builder’s preferred methods and margins — not necessarily to optimise your home’s performance or long-term value.
An independent building designer works for you. Their job is to get the best possible outcome for your home and your budget, then help you find the right builder to deliver it.
Ask yourself these questions:
If you answered “yes” to any of the last three, a building designer will likely deliver better value than a draftsman — even if the upfront fee is higher. For more guidance on finding the right professional, see our article on how to choose a building designer on the Gold Coast.
A draftsman can draw up plans for a second storey, but the design complexity — structural load paths through the existing ground floor, wind loading for the Gold Coast region, and the impact on existing foundations — really calls for a building designer. A designer will coordinate with the structural engineer from the outset rather than handing off drawings and hoping the engineering works out.
For a straightforward single-storey renovation, a draftsman might charge $2,000 to $5,000. A building designer will typically charge $5,000 to $15,000 or more depending on complexity. However, the designer fee often pays for itself through fewer variations during construction and designs that builders can price competitively. We cover this in detail in our building designer cost guide.
It depends on the site. A simple granny flat on a flat lot with no overlays could be handled by a draftsman using a standard plan. But many Gold Coast properties have constraints — flood overlays, easements, setback limitations, or stormwater requirements — that benefit from a designer’s involvement. A building designer can also help you make the most of the allowable footprint and ensure the granny flat adds genuine value to your property.
No, although there is significant overlap in the services they provide. An architect holds registration with the Board of Architects of Queensland and has completed a university degree in architecture. A building designer holds a QBCC licence and may have come through a diploma pathway, a degree, or extensive industry experience. For residential renovations on the Gold Coast, a building designer typically provides the same practical design services as an architect — often at a lower fee — and is fully licensed to design and document your project.
Yes, and it happens more often than you might expect. Homeowners sometimes start with a draftsman to save on fees, then realise the project needs more design input than anticipated. The earlier you switch, the better — reworking partially completed drawings adds cost. If you are unsure which professional you need, have a conversation with a building designer first. A good one will tell you honestly if a draftsman would be sufficient.
If you’re planning a renovation on the Gold Coast and want to make sure you’re starting with the right professional, get in touch with Design Science. We’ll have an honest conversation about your project and whether a building designer is the right fit — or if a draftsman would genuinely serve you better.
