The default answer — a long, tall fence — is usually the wrong one.
When people feel overlooked, the instinctive response is to picture a taller, longer boundary fence running the full width of the section. That instinct is usually solving the wrong problem at the wrong scale. Privacy issues almost always come from one or two specific vantage points — a neighbour's upstairs window, a deck at an angle to your outdoor living area, a new second-storey build next door — not from every possible sightline along an entire shared boundary. Treating the whole boundary when only one sightline is the actual problem means paying for coverage nobody needed and often creating more visual bulk and shade than the situation called for.
A more precise approach starts by standing exactly where the discomfort happens — the outdoor seating area, the kitchen window, the spot by the pool — and tracing exactly where the overlooking view originates from. That single piece of information usually narrows the fix to a specific height, a specific length and a specific position, which is very often smaller, cheaper and less visually heavy than a boundary-length solution would have been.
This page works through that diagnostic process first, then the cost drivers and material comparisons that follow once the actual problem is precisely understood rather than assumed.
01 · Diagnose before you screen
Map the actual problem first.
Sightline source
Stand at the seating or window in question and identify precisely where the overlooking view originates — often a specific window or deck, not a whole property. This single step usually reveals that the real problem is narrower than it first felt.
Height needed
Screening height is set by the sightline geometry, not a default fence height — sometimes less is enough, sometimes more is required. A screen built to a standard fence height can still leave the actual overlooking view untouched if the geometry wasn't checked first.
Wind interaction
Solid screens in exposed locations can create turbulence; permeable options often perform better in windy sites, and a screen that solves privacy but makes the space windier hasn't actually solved the underlying comfort problem.
Boundary relationship
Screening near a shared boundary should account for the neighbour's outlook and any relevant fencing rules, and a considered approach here tends to avoid the disputes that a purely self-interested design can provoke.
02 · Cost drivers
Height, length and material each move the price differently.

04 · Worked scenarios
Two privacy problems.
Neighbouring two-storey deck overlooking a courtyard
A single targeted screen panel at the specific sightline resolves the issue without enclosing the whole courtyard boundary, keeping most of the outlook and light intact while blocking the one angle that actually mattered.
New subdivision with close-set houses
Multiple sightlines across a smaller section point toward a combination of boundary planting and one or two built screen sections rather than a single long screen, since close-set housing rarely has just one problem angle to solve.
05 · Before you screen
Confirm the brief is specific.
- Photograph the actual overlooked view from the seating or room in question.
- Test height requirements with a temporary marker before committing to a permanent structure.
- Check any height restrictions that may apply near the boundary.
- Consider the neighbour's outlook — a considered screen reduces disputes.
Privacy screening: common questions
How do I work out the minimum height a screen actually needs to be?
Stand at the exact spot you want privacy from — a chair, a window — and use a temporary marker (a pole, a sheet, a tape measure held up by a helper) at the proposed screen location to test different heights before committing to a permanent structure.
Is a solid screen always more private than a permeable one?
Not necessarily in practice — a well-positioned louvred or slatted screen angled correctly can block a specific sightline just as effectively as a solid panel, while performing better in wind and casting less shade.
Do I need my neighbour's permission to put up a privacy screen?
If it's entirely on your own land and not attached to a shared boundary structure, generally no — but height restrictions can still apply depending on your council's rules, and discussing it with the neighbour is good practice regardless.
Can privacy screening double as wind shelter?
Often yes, and it's worth designing for both at once — a screen sized and positioned for a sightline can frequently be adjusted slightly to also improve shelter for an adjacent outdoor living space, without much extra cost.
