Many homeowners use these terms interchangeably, but there are meaningful differences in qualifications, scope, and value.
A building designer holds a QBCC licence and takes design responsibility. They make design decisions — layouts, spatial relationships, materials, environmental response — and sign off on the design. For a more detailed exploration of this distinction, see our guide on whether you need a building designer or draftsman for your Gold Coast renovation.
A draftsman produces technical drawings, translating design decisions into documentation. In Queensland, anyone independently providing building design must hold a QBCC licence — making them effectively a building designer.
For a broader comparison of design professionals, see our guide on building designer vs architect.
If you have complete concept plans from an architect and just need documentation. If you’re making minor changes to existing approved plans. If the design is predetermined and only needs drawing up.
For most new projects — custom homes, renovations, extensions — you need a building designer who provides design thinking, code compliance, problem solving, consultant coordination, and council management.
| Service | Typical Cost | What You Get |
|---|---|---|
| Drafting only | $1,500-$4,000 | Working drawings from provided concepts |
| Full building design | $3,000-$18,000 | Concept, development, documentation, approval |
For detailed fee information, see our guide on building designer costs.
Understanding what a licensed builder knows that a draftsman doesn’t helps explain why construction experience matters in design.
Check QBCC website. Search by name or licence number. Confirm licence class is “Building Design” and status is “Current.” For more on choosing the right professional, see our guide on how to choose a building designer.
Some builders offer design-and-build. The design is done by a designer engaged by the builder. Convenient but means you don’t own plans independently.
Your sketches are valuable as a brief, but a QBCC-licensed designer must take professional responsibility for the design and documentation.
Minimum Certificate IV in Building Design Drafting. For independent work: QBCC Building Design licence required.
For most Gold Coast projects, you need a QBCC-licensed building designer. The term “draftsman” is used colloquially, but the professional you need takes responsibility for design, documentation, and approval.
