What You Need to Know


What is a Shadow Diagram?

Shadow diagrams are a planning submission requirement that provides a visual model of how the proposed development will cast its shadow. Further, the shadow analysis will demonstrate any potential impacts on shadow sensitive areas, such as public spaces, communal amenity areas, traditional and arterial main streets and residential private outdoor amenity areas and how these impacts can be mitigated.

The diagrams form part of the assessment process to ensure the amenity of surrounding properties is protected to an appropriate standard.

Shadow Diagrams are typically presented in Top down Birds Eye view of the development, however with our digital technology we can provide you with much more.

Why Shadow Diagrams?

Sunlight Response

By learning in detail how your project responds to sunlight, you can:

  • Improve operating efficiency and occupant comfort
  • Avoid (or mitigate) dangerous or adverse conditions such as glare and shadow
  • Optimize your strategies for solar power generation
Better Design Outcomes
Help architects and interior designers to create a more sustainable design and green architecture by simulating daylight and sun impact on a project.
Daily Life Impacts

Sunlight and shadows affect people and their use of open space all day long and throughout the year, although the effects vary by season. Sunlight can entice outdoor activities, support vegetation, and enhance architectural features, such as stained glass windows and carved detail on historic structures. Conversely, shadows can affect the growth cycle and sustainability of natural features and the architectural significance of built features.


Shadow studies can be done to identify when and how much a particular structure will be shading another. They are also useful to determine how much a proposed adjacent building will shade an existing.


When should you use a Shadow Diagram?

Shadow Diagrams are required for all Development Applications (DAs), Planning Permits and other Development Documentation (state and territory specific) submitted to council. Shadow studies play a crucial role in identifying the solar impact, in terms of shading, that a proposed development will have on its surrounding environment which allows for informed planning and design decisions to be made.

How are Shadow Diagrams created?


Develop 3D Models

To begin the project, using a computer aided design (CAD) software, we will create a 3D model of your project and any necessary adjacent buildings. 

Context Map

We have access to the highest quality spatial data of Australia to create context maps. This allows us to place your building within its real world context and create your shadow diagrams with incredible accuracy.


Shadow Simulation

Once all models are together we will use building information modeling (BIM) software to begin simulations to show the expected shadows cast by the Development proposal for 9am, 12 noon and 3pm at both winter and summer solstice (unless requested otherwise). 


Final Report

On completion of all simulations we are able to provide a diagrammatic analysis with basic commentary of the shadow impacts that your development will create.

What is required to create a Shadow Diagram? 

To create a shadow diagram for you all we need is the survey that has been prepared for the development application (DA) by a registered surveyor and/or the architectural plans prepared for DA submission in either DWG or PDF format. 

However, please don't hesitate to contact us if you do not have these files we would love to chat with you and work out how we can help. 

To get your Shadow Diagram started, simply fill out the form below and provide us with some details about your project.

How long does it take to create a Shadow Diagram?


The time it takes for us to complete your project is dependent on the size of the project that needs to be modelled. Small projects can be modelled in minimum 8-10 hours with a 5-10 day turn around from quote to completion.

How much does it cost?

The cost for Shadow Diagrams depends on the size and complexity of the project, depending on the amount of time that is required to fully model and assess the building.
