What are construction drawings?

Construction drawings are detailed technical documents that guide the entire building process.

They usually include:

✔️ Floorplans

Precise layouts with dimensions, room sizes, and functional flow.

✔️ Elevations

Exterior views showcasing heights, materials, and key design elements.

✔️ Siteplan

Placement of the building in relation to boundaries, setbacks, and site levels.

✔️ Electrical & Plumbing Plans

Plans for lighting, power outlets & plumbing points

✔️ Sections & Details

Cross-sections showing structural details, ceiling heights, and finishes.

✔️ Roof Plans

Detailed roof layouts, pitches, and drainage specifications.

✔️ Internal Elevations

for wet areas such as Kitchen, Bathroom, Ensuite & Laundry.

FAQs

  • How long does it take to complete construction drawings?

    The timeframe depends on the size and complexity of the project. A standard residential home typically takes 1-3 weeks, while larger or more detailed projects may take longer.

  • Can I make changes after the drawings are completed?

    Yes, but changes after finalisation may require revisions, which can affect approvals and construction timelines. It’s best to finalise all design decisions before completing the drawings to avoid delays.

  • Do I need construction drawings for a renovation or extension?

    Yes. Even if it’s a minor renovation, detailed plans ensure the work is done correctly, meets council requirements, and avoids costly surprises during construction.

  • Can you modify an existing set of drawings?

    If you already have plans but need modifications, we can revise them to ensure they meet your new requirements, comply with regulations, and are builder-friendly.

  • Will these drawings be enough for council approval?

    In most cases, yes. However, depending on your project, you may also need engineering reports, energy efficiency assessments, or additional compliance documents. We can guide you through this process.

  • Can my builder work directly from these drawings?

    Absolutely. Our construction drawings are detailed and builder-friendly, ensuring smooth communication between you, your builder, and other trades.

  • What’s the difference between concept drawings and construction drawings?

    Concept drawings are preliminary sketches that explore the design and layout of your project.

    Construction drawings are the detailed, technical documents used for approvals and building.

  • Do you provide structural engineering drawings as well?

    No, but we can coordinate with structural engineers to ensure your drawings are fully compliant. If your project requires engineering, we’ll advise you on the next steps.

  • What format do I receive the final drawings in?

    You will receive the final construction drawings in PDF format (ready for council submission and builder use). If required, we can also provide DWG files for engineers and consultants.
