HOW TO READ CONSTRUCTION PLANS IN AUSTRALIA: A GUIDE FOR BEGINNERS

Navigating the realm of construction or considering a renovation, establishing a new store, or building a home can seem daunting, particularly when it comes to interpreting construction plans. However, it's simpler than it appears. In this blog post, we're here to guide you through the essential aspects of reading construction blueprints in Australia. We will elucidate the varied symbols and abbreviations and demystify the plan's layout.

This guide is perfect for contractors needing to review plans before starting a project, or homeowners and business owners wanting to grasp builder's terminology. Equip yourself with the knowledge to comprehend construction plans effectively with our straightforward guide.

To make this guide more relatable, we will use real-world examples from our recent projects, namely the Gloss Nail Lounge and the Challenger Security project. A huge thanks to Rogue Architects for allowing us to utilise their plans.

Gloss Nail Lounge Floor Plan

Floor Plans

  • Provides a bird's eye view of the project.

  • Visualizes walls, doors, windows, staircases, and furniture placement.

  • Ideal for understanding the spatial arrangement within a building and planning for safety measures.

A floor plan offers an overview of the project, enabling you to visualize the layout and comprehend spatial relationships. It's particularly beneficial for planning movement patterns and furniture placement, thus optimizing space utilization. Furthermore, a clear view of the project's layout is crucial for devising safety plans, such as emergency exits and hazard prevention.

Elevation Plans

  • Shows one side or elevation of the project.

  • Essential for understanding the building's height and the appearance of specific features.

  • Crucial for verifying the building's external aesthetics and alignment with design goals.

An elevation plan facilitates the understanding of how the building will fit into its surroundings. It offers details about materials, window styles, roof slopes, and other exterior elements, providing an insight into the final look of the building.

Perspective View

  • Offers a 3D view of the project.

  • Beneficial for realistic visualization of the project.

  • Provides understanding spatial relationships and overall aesthetics.

A perspective view serves as a tool for presenting the project in a way that stakeholders can easily understand. It showcases how various elements of the building come together to create the overall aesthetic, helping ensure alignment with design goals.


Thanks to advancements in modern technology, perspective views have largely transitioned into the realm of digital renders. The complexity of these digital representations can range significantly - from meticulously detailed, almost photographic renditions (as seen in Image 3), to more simplistic, line-based interpretations (evident in Image 4).

Section View

  • Shows a cutaway view of the interior.

  • Key for understanding the construction details of specific features.

  • Helpful for grasping interior functioning and alignment with design goals.

A section view enables the understanding of the internal structure of a building, showing elements like beams, footings, insulation, roof profiles, and more. This is crucial for planning and verifying that the interior layout aligns with the design goals.

Reflected Ceiling Plans (RCP)

  • Provides a view of the ceiling layout.

  • Important for locating light fixtures, sprinklers, and other ceiling installations.

  • Essential for planning the placement of ceiling-mounted features.

A reflected ceiling plan provides a view from below, illustrating the positioning of ceiling-mounted features like light fixtures, sprinklers, air vents, and more. It is a key document for coordinating mechanical, electrical, and plumbing services.

Decoding Symbols and Abbreviations

  • Symbols and abbreviations are shorthand for common elements in construction plans.

  • Essential for quick and accurate understanding of construction plan details.

  • Encourages clear communication among stakeholders.

Symbols and abbreviations in construction plans act as a universal language, simplifying complex details and making plans less cluttered and more readable. Understanding these symbols ensures accurate interpretation of the plan, facilitating clear communication among stakeholders.

Build.com.au have put together a great cheat sheet here for most of the symbols and abbreviations you are likely to find on construction plans. Keep in mind that these can change depending on your designer.

Understanding Drawing Scale

  • Construction plans are usually drawn to scale.

  • Essential for accurate perception of space and feature sizes.

  • Aids in planning and execution of construction work.

The scale in construction plans depicts the proportion between the elements in the plan and their actual size in reality. Grasping this scale is crucial for preventing misunderstandings about spatial relationships and ensuring successful project completion. It's especially significant for tasks such as cost estimation and material ordering, which require accurate dimensions provided in the plan.

Another important thing to keep in mind when learning how to read construction plans is that they are usually drawn to scale. This means that each element on the plan is represented in proportion to its actual size. It’s important to note that the scale is only accurate when printed at the given size (e.g. A3, A2).

For example, the floor plan below is represented at a scale of 1:100 at A3 Size. This means that every 1cm on the plans is equivalent to 1m in the real build. In the images below you can see the office wall is 7.1cm in the printed plans, which equates to 7.1m in the build.

Acquiring proficiency in reading construction plans is a process that requires time and practice. However, with patience and persistence, you'll soon find yourself navigating construction plans with ease and confidence, ensuring your projects run smoothly and successfully.

This is helpful for understanding things like how much space you have to work with or how big certain features will be. Just remember that not all plans are drawn to scale, so always ask your builder or architect if you're unsure.

We hope this guide has been helpful in teaching you how to read construction plans. Just remember that it takes time and practice to get good at it. So don't get discouraged if you don't understand everything right away. With a little patience and effort, you'll be reading construction plans like a pro in no time!
