How much do shadow diagrams cost?

Short answer

The cost of a shadow diagram depends on project size and complexity, typically ranging from $500 to $2,500.

Full answer

Pricing varies based on factors like:

• Size and type of the development

• Number of diagrams required by council

• Whether 3D modelling or multiple revisions are needed

Simple residential projects may cost around $500–$800, while complex multi-storey or mixed-use developments may exceed $2,000.
