How to Add Privacy to an Overlooked London Garden (Without Making It Feel Closed In)

GARDEN DESIGN & PRIVACY | The Tree Amigos

The best way to make an overlooked London garden private is to layer your screening at different heights — a solid boundary line (such as cedar slatted fencing), a raised element where you're overlooked from above (a pergola or tall slatted screen), and planting to soften it. Layering blocks sightlines from both neighbouring gardens and upstairs windows without turning your garden into a dark, boxed-in space.

Why London gardens feel overlooked

In London's terraces, flats and tightly packed plots, the problem is rarely just the fence line — it's the upstairs windows. You can have a perfectly good boundary fence and still feel watched from a neighbour's first-floor window or a block behind you. That's why simply building a taller fence usually doesn't solve it (and often hits permitted-development height limits anyway). The trick is to screen the specific sightlines that bother you, at the height they come from.

The layered approach to privacy

• 1. The Boundary (Eye Level): Cedar slatted fencing is the premium London choice. Horizontal slats give a clean contemporary finish, and the small gaps let light and air filter through while breaking up the view. It offers a much higher-end aesthetic than traditional close-board panels and ages beautifully over time.
• 2. The Overhead and Side Angles (Above Eye Level): Where you are overlooked from above, a pergola with slatted roofing or a tall slatted screen creates a protective "lid" over your seating area so you're not exposed to upstairs windows.
• 3. The Soft Layer: Climbing plants and targeted planting against a slatted screen soften the structure and add a second visual barrier, making your privacy feel natural and organic rather than artificial.

Privacy without losing the light

The most common mistake is over-screening with solid panels everywhere, ending up with a dark, claustrophobic garden. Slatted screens and fencing let daylight filter through while obscuring the view from a distance. Only full-height screen the specific angles you're overlooked from; elsewhere a lower boundary keeps things open. A good design screens the eye, not the sky.

Fencing vs trellis vs a pergola — which do you need?

It depends where the exposure comes from. Eye-level from next door warrants fencing or a slatted boundary screen. Being overlooked from above by a first-floor window or block window means a pergola gives the necessary overhead cover. Trellis with climbers represents the lightest touch—excellent for softening or adding decorative height on an existing fence, but won't fully block a determined sightline alone. Most genuinely private London gardens use a combination of these elements.

A note on planning and fence height

Privacy screening usually falls under Permitted Development, but fences over 2 metres (or over 1 metre next to a highway) typically need permission, and conservation areas can be stricter. Make sure to check details on when Do You Need Planning Permission for a Patio or Decking in London? before committing to a design.
