Shadow Check in Northern Beaches, NSW
See how much shadow neighbouring buildings cast on your Northern Beaches property at the summer and winter solstice. Low-to-medium density, but coastal hills and stepped terrain cause shadow issues on south-facing slopes. Northern Beaches has 956 heritage items — character buildings can cast unexpected shadows. Shadow analysis works best alongside a solar yield estimate — shading directly reduces panel output. If you are planning a granny flat, check SEPP eligibility and nearby development activity in Northern Beaches.

Shadow and overshadowing in Northern Beaches — common questions
Is shadow a risk on the Northern Beaches?
Shadow risk on the Northern Beaches is moderate, with terrain being a significant factor. Coastal headlands and hillside topography mean that north-facing properties on south-facing slopes receive excellent light, but properties on north-facing slopes can be unexpectedly shadowed by neighbours on higher ground.
What causes shadow issues on the Northern Beaches?
Terrain is the most significant factor -- elevated homes on hillside blocks cast long shadows on downslope properties. Dual-occupancy and secondary dwelling additions in Dee Why, Brookvale, and Narrabeen also contribute. Heritage-affected areas like Manly and Avalon limit the most disruptive density changes.
Does heritage protection reduce shadow risk on the Northern Beaches?
Partially. Heritage conservation areas in Manly, Avalon, and Palm Beach limit demolition and replacement with larger buildings, which reduces the risk of new high-impact shadow sources in those precincts. Outside conservation areas, standard R2 development controls apply.

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.
