A design can look simple on a floor plan while being difficult to deliver on its actual site. On the Northern Beaches, start by identifying the controls and constraints at the property level rather than relying on the suburb name.

Make a constraints folder

Use Council’s planning information and the NSW Planning Portal Spatial Viewer as starting points. Ask an appropriate adviser to interpret the current controls, mapping and any relevant planning certificate. A map is an investigation tool, not a complete approval check.

  • Planning context: applicable local and state controls, heritage considerations and relevant existing approvals.
  • Natural hazards: whether bushfire, flooding or coastal conditions require further investigation.
  • Ground and boundaries: what survey, levels, easements, retaining structures or ground information your advisers need.
  • Vegetation and neighbours: trees, access, privacy, overlooking and how construction might affect adjoining land.

Ask what changes the design

For each identified issue, ask: who investigates it, when is the answer needed, what report will be produced and which design decisions depend on it? This creates a sequence for spending on consultants rather than a pile of disconnected reports.

Include buildability in the conversation

Discuss access for deliveries, material storage, temporary protection and keeping the home usable. For exposed sites, ask the designer about maintenance and material selection suited to the actual exposure. These are questions for your project team, not a specification from this directory.

Check the official sources again when you are ready to lodge. Controls and guidance may change, and a generic checklist cannot reveal every issue on a property.
