For Council and Urban Planning Submissions


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.

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

My first thought is that is a very useful tool to quickly get a base to work from. We often spend too much time trying to generate this by hand while still being pretty inaccurate.” “it’s really useful to see a 3d representation of an unknown area so quickly.
