Clarity Before You Commit
Licensed Building Designer & Builder — Gold Coast, Brisbane & South East Queensland
Dual-licensed Building Designer and Builder
Design Science is led by David Steadman — one of very few Gold Coast building designers who also holds a QBCC Builder’s licence (#15277902). With over 30 years in the building and design industry, every plan we produce accounts for how it will actually be built, what it will cost, and what a builder will encounter on site.
Construction-informed design
Most building designers work from theory. We work from decades of hands-on construction experience across Gold Coast residential and commercial projects. The result is plans that builders trust — detailed enough to price accurately, with fewer variations and no expensive surprises during construction.
Clear advice, realistic outcomes
We work with clients who value clarity. From the first consultation, we help you understand what is achievable, what it will cost, and what approvals are required — before any major commitments are made. Our service area covers the Gold Coast, Brisbane, and South East Queensland. Learn more about David’s background.
Architects, Building Designers, and Draftsmen — what’s the difference?
Architects
Architects typically provide highly detailed design services and often work on complex or architecturally driven projects. Their services are well suited to certain project types, but may not always align with every budget or scope.
Draftsmen
Draftsmen generally offer more basic documentation services and may be suitable for simpler projects. Their role is often limited in scope and does not usually include broader design development or construction advice.
Building Designers (our core discipline)
Building designers sit between these roles, providing professional, licensed design services with a strong focus on compliance, buildability, and value. At Design Science, this is further strengthened by Licensed Builder oversight — giving clients clarity, realism, and confidence throughout the process.
Planning a renovation involves hundreds of interconnected decisions — design, approvals, consultants, builders, and budget. Our renovation consulting services help you understand what is achievable, compliant, and cost-realistic before you commit.
We work with homeowners who value clear advice, experienced guidance, and practical solutions informed by real construction experience.
Consultation Fee: We charge for professional consulting and design advice. If you proceed with a design engagement, this fee is credited toward your project.

Most people begin a renovation by looking for a builder. It feels logical — until you realise a builder cannot accurately price, plan, or advise on a project that hasn’t been properly designed.
Without clear design documentation, builders are forced to make assumptions. That’s how scopes drift, costs escalate, and outcomes fall short. It’s not a criticism of builders — it’s simply the wrong sequence.
The role of a designer is to define what is being built before construction begins. But for complex renovations, the best results come from designers who also understand construction at a builder’s level — not builders who are not qualified designers.
That combined experience is what allows design decisions to be realistic, buildable, and commercially sound before you ever approach a builder.
