If you’re planning a renovation or new home, you’ve likely heard the term “architectural drawings.”

But what does that actually include?

Architectural drawings range from early concept plans through to detailed construction documentation. The level of detail depends on the stage of your project and what approvals or pricing information are required.

Below is a clear breakdown of what is typically included.

‍

1. Concept Drawings

Concept drawings are the first stage of visualising a project.

They typically include:

• Preliminary floor plans
• Site layout
• Basic elevations
• Simple 3D massing diagrams

These drawings focus on layout, flow, and overall form rather than construction detail.

They are used to explore ideas and establish direction before technical work begins.

‍

2. Developed Design Drawings

Once a concept is approved, drawings become more refined and accurate.

These often include:

• Dimensioned floor plans
• Roof plans
• Elevations
• Building sections
• Window and door locations

At this stage, the design is aligned with site constraints, budget considerations, and regulatory requirements.

‍

3. Planning or Approval Drawings

If your project requires approval, additional drawings may be prepared.

These may include:

• Site analysis plans
• Shadow diagrams
• Streetscape elevations
• Overlay or compliance documentation

The purpose of these drawings is to demonstrate compliance with local planning controls.

‍

4. Construction Documentation

Construction drawings are the most detailed stage.

They provide builders and consultants with precise information to price and construct the project accurately.

These typically include:

• Fully dimensioned floor plans
• Detailed sections
• Construction details
• Joinery layouts
• Materials and finishes schedules
• Notes and specifications

Without this level of documentation, builders may rely on assumptions, which can lead to cost variations during construction.

‍

5. Consultant Coordination

Architectural drawings often integrate information from:

• Structural engineers
• Energy assessors
• Hydraulic designers
• Landscape designers

Coordination ensures the design works structurally, functionally, and compliantly.

‍

Why the Level of Detail Matters

The more detailed the drawings, the clearer the build process becomes.

Detailed documentation helps:

• Improve pricing accuracy
• Reduce variations
• Minimise site confusion
• Protect design intent

In contrast, minimal drawings may result in interpretation gaps during construction.

‍

Do All Projects Need Full Documentation?

Not always.

Small internal renovations may require limited documentation, while new homes or major extensions typically require a full construction package.

The required level depends on:

• Project size
• Structural complexity
• Approval requirements
• Budget clarity

‍

Final Thoughts

Architectural drawings are more than just floor plans.

They evolve from early ideas into precise documentation that guides approvals, pricing, and construction.

Understanding what is included at each stage helps you ask the right questions and ensures your project is properly prepared before building begins.
