Shadow and overshadowing in Sutherland Shire — common questions
Is shadow a risk in the Sutherland Shire?
Shadow risk in the Sutherland Shire is low to moderate. Larger suburban lots and predominantly 1-2 storey housing provide reasonable separation. The main shadow risk comes from secondary dwelling additions and new 2-storey knockdown-rebuild projects on properties directly to the north.
What causes shadow issues in the Sutherland Shire?
Secondary dwelling additions to rear yards of neighbouring properties are the most common cause in established suburbs. Knockdown-rebuild projects replacing single-storey homes with 2-storey dwellings also increase shadow on adjoining properties.
Are there shadow risks near national parks in the Sutherland Shire?
Properties near Royal National Park generally have low shadow risk from built development given the adjacent open space. Terrain shadow from bushland ridgelines can be a factor on south-facing slopes but is not related to neighbouring development.

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.
