Shadow and overshadowing in Wollongong — common questions
Is shadow a risk in Wollongong?
Shadow risk in Wollongong is moderate. The escarpment causes terrain shadow for some properties in the afternoon, and medium-density development near Wollongong CBD creates built shadow risk. In established suburban areas the risk is low to moderate.
What causes shadow issues in Wollongong?
Terrain shadow from the Illawarra escarpment affects western-facing properties in the afternoon. In the city and inner suburbs, medium-density apartment and townhouse development creates shadow risk for existing single and 2-storey homes. Secondary dwelling CDCs in suburban areas are also a source.
Are escarpment-adjacent properties more shadow-affected in Wollongong?
Properties immediately east of the escarpment can receive reduced afternoon sun during winter when the sun is lower in the sky. This terrain shadow cannot be addressed through the planning system. The shadow tool above models building shadows only -- terrain shadow requires a separate analysis.

Shadow analysis uses building footprints and height data from NSW Spatial Services aerial imagery. The ADG 3-hour minimum applies to habitable rooms in new residential development assessed under the Apartment Design Guide. Results are indicative only -- actual shadow impact depends on exact roof pitch, vegetation, and neighbouring building heights. Not planning advice.
