Start With the Rules, Not the Railing

Before you buy a single trellis or unwind a roll of reed screening, spend ten minutes with your lease or tenancy agreement. Balconies sit in an awkward middle ground: the inside of your front door is yours, but the structure — railings, walls, ceilings, drainage — usually belongs to the freeholder or landlord, and they tend to have opinions about what gets fixed to it.

Things worth checking specifically:

• Whether you're allowed to drill into walls, ceilings or railings at all.
• Whether screens or planters may be attached to the railing, and whether they must be removable.
• Any weight limits, which matter far more than most people expect once compost gets rained on.
• Whether your building has rules about what's visible from the street, common in conservation areas and newer blocks.
• Fire safety guidance, particularly on upper floors, where combustible screening can be restricted.

If the answer is "nothing fixed, nothing permanent", don't despair — almost everything below can be done with freestanding, tension-based or weighted solutions. A short, polite email to your managing agent or landlord is far less painful than being asked to take it all down in August.

Screening Plants That Actually Cope With Balconies

Balconies are brutal little microclimates. Wind whips around corners, rain rarely reaches the wall side, and sun bakes south-facing railings. Choose plants that shrug this off rather than ones that merely look good in a garden centre.

Reliable choices for containers:

• Bamboo — Fargesia varieties are clumping rather than running, and they make a dense, tall screen quickly. Keep them in a generous pot and water diligently.
• Photinia 'Red Robin' — evergreen, tolerant of pruning, and happy enough in a large container to give you year-round cover.
• Elaeagnus — tough as old boots, silvery foliage, and it copes with wind and coastal salt.
• Ornamental grasses — miscanthus and stipa sway in the breeze rather than snapping, which softens a view without blocking light.
• Trailing ivy or jasmine — for railings, where you want green rather than opaque. Both are fast and forgiving.

Aim for a mix of heights. A row of identical pots at identical heights reads as a fence, whereas tall at the back, medium in the middle and trailing over the front edge reads as a garden. Use the largest pots you can reasonably fit — 40cm diameter and up — because small pots dry out twice a day in summer and plants sulk.

Reed Fences and Screening Rolls Without Drilling

Reed, willow and brushwood screening is the quickest route to privacy and the most common thing neighbours ask about. It's cheap, lightweight and it filters light so your balcony doesn't turn into a cave.

If you can't fix anything permanently, you still have options:

• Tension poles that grip between floor and ceiling, with the screening cable-tied to them.
• Weighted bases at each end of a freestanding frame, using paving slabs or water-filled containers. This is the most lease-friendly approach of all.
• Zip ties around the railing — technically not drilling, and often permitted, but check first.
• Existing fixings — many balconies already have hooks or brackets from a previous occupant. Reuse them where you can.

Buy screening slightly taller than you need. Overlooking neighbours are usually looking down, so an extra 20–30cm above the railing makes a disproportionate difference. And secure the top edge: loose reed screening in a gust will flap, fray and eventually end up in someone's garden below.

Tall Planters as Movable Walls

This is the trick I'd recommend to anyone who can't fix anything to anything. A row of tall, narrow planters along the edge of a balcony creates a screen, a windbreak and a bit of a room at the same time — and it's entirely freestanding.

Look for planters at least 70–80cm tall, ideally with a built-in trellis panel at the back. Fill the lower third with gravel or broken crocks for drainage and stability, then compost above. Plant something evergreen and let it grow through the trellis. Two or three of these, angled slightly, will block a sightline without cutting you off from the view you actually want to keep.

Be honest about weight. Wet compost is heavy, and a large planter can easily reach 40–50kg. Spread them along the balcony rather than clustering them on one end, and check your lease for loading limits.

Light, Air and the Feeling of a Room

Privacy that turns your balcony into a dark box isn't privacy, it's storage. Screen the specific line of sight you're worried about — usually one neighbour's upstairs window or a particular stretch of road — and leave the rest open. A corner screen is often enough.

Add a few finishing touches that make the space feel intentional rather than barricaded: a small outdoor rug, a folding bistro table, a couple of cushions kept in a weatherproof box, and warm low-level lighting on a timer. Once you have a surface to put a mug down on and something soft underfoot, the screening stops reading as a barrier and starts reading as a wall of your own little room.

Watering is the one chore that never goes away. A small watering can kept on the balcony, plus a saucer under each pot to catch runoff, will keep you on the right side of the neighbours downstairs.
