See how much shadow neighbouring buildings cast on your Ku-ring-gai property at the summer and winter solstice. Large established trees and 2-storey dwellings on sloping blocks are the main shadow sources. Ku-ring-gai has 1,046 heritage items — character buildings can cast unexpected shadows. Shadow analysis works best alongside a solar yield estimate — shading directly reduces panel output.

Shadow and overshadowing in Ku-ring-gai — common questions

Is shadow a risk in Ku-ring-gai?

Shadow risk in Ku-ring-gai is moderate. The combination of large established trees, 2-storey heritage homes, and sloping terrain means many properties experience more winter shadow than appears from a map. Heritage conservation areas limit the worst density changes but do not eliminate shadow risk from existing buildings.

What causes shadow issues in Ku-ring-gai?

Large established trees in rear yards are a significant source, alongside 2-storey Federation and interwar homes on sloping lots that cast long shadows on lower-lying neighbours. Near station precincts (Gordon, Turramurra), medium-density development creates shadow risk for adjacent single-storey properties.

Does Ku-ring-gai's heritage status protect against shadow?

Heritage conservation areas restrict demolition and replacement of heritage items, which limits the risk of a new large building appearing where a single-storey cottage once stood. However, existing large dwellings and trees in conservation areas still cast shadow -- heritage does not address existing shadow sources.

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.
