An overshadowing report is a specialised document that evaluates the extent to which a proposed development or existing structure may cast shadows on neighbouring properties, public spaces, or solar-sensitive areas like gardens, courtyards, and windows. Commonly required as part of a Development Application (DA), it demonstrates compliance with local planning regulations, including minimum solar access requirements.
The report typically includes:
Shadow diagrams: Visual representations illustrating shadows at key times (e.g., 9:00 AM, 12:00 PM, and 3:00 PM) during various seasons, particularly the winter solstice when shadows are longest.
Impact analysis: An assessment of shadow effects on nearby properties, with a focus on sunlight access to habitable rooms and outdoor areas.
Compliance review: A comparison of shadow impacts against council regulations to confirm alignment with solar access standards.
Mitigation strategies: Suggested design adjustments to minimise adverse overshadowing if necessary.
Overshadowing reports play a vital role in balancing urban development with the right to sunlight for neighbouring properties. Concerned about a new development that could impact your solar access?
