🏗️ 1. Can I change or modify a design?

Absolutely!
You can easily make changes to any of our designs. Simply purchase the CAD file with your chosen plan, then take it to your local draftsman or builder to modify it to suit your exact requirements.

💡 Tip: This option gives you complete flexibility to adapt the design to your land, family needs, or personal style.

📄 2. What do the prices on your website include?

Each design has two options:

  • Preview Set – Includes

    • Dimensioned floor plans (pdf format)

    • External elevations (pdf format)

  • Working Set – Includes

    • Dimensioned floor plans (pdf format)

    • External elevations (pdf format)

    • DWG/AutoCAD files (these will give you the ability to build and/or modify the design). These will be needed in order for the working drawings to be completed. 

🧱 You’ll always know exactly what you’re getting — no hidden costs.

🧩 3. What Are CAD Files and Working Drawings?

When you purchase a design from Australian House Designs Group, you’ll notice we only offer CAD files to be purchased. You will need to contact us for a quote to complete the Working Drawings for you or you can hire a local professional
Although both relate to your home design, they serve very different purposes depending on what stage you’re at in the building process.

📐 What are CAD Files?

CAD stands for Computer-Aided Design.
These are the editable, digital design files (usually in .dwg or .dxf format) that contain all the geometric data, lines, and layers used to create your home design.

CAD files are primarily used by building professionals — such as draftsmen, architects, engineers, and builders — who work with CAD software like AutoCAD or Revit.

CAD Files are ideal for:

  • 🧱 Making modifications to the design (e.g. adjusting room sizes or layouts)

  • 📏 Customising the plan for local council or developer requirements

  • 🏗️ Adding engineering details, structural drawings, or energy efficiency reports

  • 💡 Creating 3D renders or marketing materials

Essentially, CAD files are your editable “master copy.”
They give you (or your chosen draftsman/builder) full flexibility to adapt and re-use the design as needed — without starting from scratch.

💡 When you purchase CAD files from AHDG, you also receive full permission to modify the plans for your own use.

🏠 What are Working Drawings?

Working Drawings (sometimes called Construction Drawings) are the final, ready-to-build version of your chosen design.
These are complete, professional drawings that are ready for builder quoting, council submission, and construction.

Working Drawings typically include:

  • 📄 Floor plans with all dimensions

  • 🧱 Elevations (front, side, and rear views)

  • 📐 Sections and roof plans

  • ⚙️ Door and window schedules

  • 📋 Notes and details required for building approval

🌏 4. Can I buy plans if I live interstate or overseas?

Yes, absolutely!
We proudly serve clients across Australia and internationally.
Our licences cover every Australian state except Tasmania.

✅ Please check your local council’s building requirements before submission, as you may need to include region-specific changes.

🏡 5. Do you offer renovation design services?

AHDG no longer provides renovation services directly.
However, our sister company Empire Designs specialises in custom home designs, renovations, and extensions.

🖋️ Visit Empire Designs for personalised, one-on-one design services.

🏛️ 6. Do you submit the plans to council for me?

No — but don’t worry, it’s simple!
Recent updates to council processes have made submissions much easier for clients to handle themselves.

📬 We are happy to help guide you through the process.

♻️ 7. Do you handle BASIX reports in-house?

Not currently.
You’ll need to engage a local BASIX provider if your project requires one.

💧 We can help you understand what information they’ll need from your plans.

💰 8. Why are your plans so affordable compared to other designers?

We believe great design should be accessible and affordable.
Our plans are priced lower because all the design and documentation work is already completed.

That means:

  • No design delays

  • Lower design costs

  • Instant access to professional, build-ready drawings

⚡ We pass those savings directly to you — without compromising quality.

✏️ 9. Do you do custom designs or can I provide my own plan?

Absolutely. Please see our Custom Designs Page for more information. 

👷 10. Are you also builders?

No — we’re building designers, not builders.
However, we have trusted partnerships with reputable builders throughout Queensland.

If you’re building in Brisbane, we’d be happy to recommend one of our preferred local builders.

🔨 We design — they build! The perfect team for your project.
