Privacy Design for Granny Flats + Dual Occupancies NSW (Without Turning Your Yard Into a Fort)

Privacy is where “looks good on paper” designs fall apart.

If your granny flat or duplex creates direct overlooking, it will get flagged—by council, by neighbours, or both.

NSW low-rise design guidance consistently highlights privacy as a core design factor. Planning NSW

Quick answer: how to design privacy properly

Use a combination of:

• window placement (primary tool)
• level changes (careful with split levels)
• screening (secondary tool)
• landscaping (high-value tool) Fencing is the last resort, not the plan.

1) Window strategy: start here

Most privacy failures are “window-to-window”.

Fix it with:

• offsetting windows so they don’t stare at each other
• highlight windows for bathrooms/stairs
• sill heights where appropriate
• limiting full-height glazing on side boundaries

2) Outdoor privacy matters as much as indoor

The best granny flats and duplexes have outdoor areas that feel usable because they’re not being watched.

Create:

• a defined outdoor room (pergola / planting / screen)
• a privacy buffer zone (garden bed + planting)
• separation between dwelling entries

3) Upper floors: avoid “backyard surveillance”

Two-storey designs commonly fail by putting big windows directly over neighbour yards.

Solutions:

• orient windows to your own space
• use smaller openings where needed
• screen balconies properly
• step upper levels back

4) Acoustic privacy: the thing nobody thinks about until it’s too late

Dual occupancies are not just visual.

Good acoustic separation often comes from:

• separating bedrooms with non-habitable spaces (stairs, bathrooms)
• thoughtful wall build-ups (your designer + builder handle specifics)
• not placing outdoor entertaining zones back-to-back

FAQs: Privacy Design NSW

Will council accept privacy screens?

Often yes, if they look integrated and don’t create other problems (bulk/streetscape). But it’s better if the plan reduces overlooking first.

Can landscaping “count” as privacy?

It helps massively in real life. It also improves streetscape and perceived value.
