A typical British courtyard is not much to look at: three or four metres square, a brick wall on two sides, a back door, a drain in the corner and whatever light manages to squeeze in. That smallness is usually described as a problem. For a Zen-style garden it is the whole point. Raked gravel gardens were made to be viewed from a seated position in a confined space, and the discipline of using very little — stone, gravel, a handful of plants — is exactly what a courtyard can carry off without looking cramped.
The aim is not to recreate a temple garden in Kent. It is to borrow the principles: restraint, clean lines, one strong focal point, and a surface that changes each time you rake it. Here is how to plan one properly.
Read the space before you buy anything
Spend a week watching the courtyard before you commit. Note where the sun lands and for how long. A north-facing yard with a high wall may get two hours of weak light in winter and almost none in the middle of the day; that rules out sun-lovers such as thyme and lavender, and pushes you towards ferns, moss and acers. Check where water sits after heavy rain — pebbles laid over a surface that already ponds will simply float a grey scum of silt and algae into view. Look at what the neighbours can see from their upstairs windows. And stand at the door you use most, because that sightline is the one the garden has to work for.
Make a note of materials you are keeping. Old brick, a stone sill, a cast-iron drain cover — these can be left as they are rather than hidden. A courtyard that acknowledges its own architecture looks intentional; one that fights it looks like a display stand.
Choosing and laying the pebble bed
Stone size and type
For areas you rake, 14–20mm washed gravel or pebbles are the sweet spot. Anything smaller than about 10mm is dusty, muddy underfoot and impossible to rake cleanly; anything above 40mm is heavy to move with a rake and feels like a builder's yard. Colour should be quiet and consistent.
- Cornish silver or grey gravel — soft, coastal, works well with slate and brick
- Scottish pebbles — rounded, calmer underfoot, good for paths
- Slate chippings — dark and dramatic, but they hold heat and show every leaf
- Pale limestone or Cotswold gravel — brightens a shaded yard, but can glare in full sun
- Geotextile membrane — permeable, not solid plastic sheeting, which traps water
- Edging — steel strip, granite setts or bricks laid on edge to stop stone migrating into soil
Laying it
- Mark out the beds and any path with string lines and canes.
- Lift turf or old paving and dig out roughly 75–100mm.
- For anything walked on, add and compact a sub-base of MOT Type 1, then level it.
- Roll out the membrane, overlapping joins by at least 100mm, and tuck the edges under the edging.
- Set the edging firmly. This is the detail that keeps the design crisp for years.
- Spread 40–50mm of gravel and rake it into your chosen pattern.
If you want a shallow rill or a dry stream, dig the channel before the membrane goes down, line it, and use larger stones at the edges. Keep a spare bag of gravel in the shed; you will lose a little each year to shoes, birds and the wind.
Raking is the design
The rake marks are not decoration applied at the end — they are what makes the surface read as water, or wind, or stillness. Buy a wide-toothed wooden or bamboo rake, the sort sold for gravel gardens, and work when the stone is dry. Wet pebbles clump and the lines look smeared.
Straight parallel lines suit a narrow courtyard and make it feel longer. Curves work better when there is something to curve around: sweep them towards a stone or a plant, never away from it. Concentric rings around a single boulder look deliberate and take four minutes. Keep the lines flowing in one direction across the whole garden rather than changing pattern in each corner.
Rain, cats and blackbirds will ruin it within a day or two. This is not a failure. Raking is the point — a ten-minute job with a cup of tea, and the reason the garden stays restful rather than finished.
Plants that earn their place
In a gravel garden, plants are accents, not borders. Use three or four species, plant them in odd-numbered groups, and leave generous gaps of open stone between them. Anything that self-seeds freely or spreads by runners will undermine the whole effect.
Good choices for a UK courtyard include a small acer in a pot or a sheltered corner, where its leaf colour does the work of a dozen flowers; Hakonechloa macra, which spills over gravel beautifully; ferns such as Dryopteris erythrosora and our native hart's-tongue for shaded walls; and moss encouraged on damp stone by watering it in dry spells. For a sunny, free-draining corner, thyme, sedum and saxifrage will knit into the stone. If you want bamboo, choose a clumping Fargesia rather than a running Phyllostachys, and keep it in a pot unless you enjoy a weekly battle with underground shoots.
Focal points, sound and light
One focal point is enough. A stone lantern, a single large boulder, a weathered piece of wood, or a granite basin with a bamboo spout all work. Place it off-centre, roughly a third of the way across the view from the door, so the eye has to travel a little to reach it. Anything symmetrical in a courtyard this size tends to look like a traffic island.
Water adds sound, which matters more than most people expect in an overlooked urban space. A trickle from a small basin or a simple pump is plenty. Have any outdoor power supply installed by a qualified electrician, and keep cables out of reach of children and pets.
Lighting should be low and warm: one or two small spots uplit into a tree or a lantern from its base, not a floodlit patio. If the courtyard is overlooked, use a bamboo or slatted screen on the worst side, painted a dark grey or green so the boundary recedes.
Making it work in practice
Most of this can be done over two weekends: one to lift, level, membrane and edge; one to lay stone, plant and place the focal point. Then leave it alone for a season before adding anything else.
Maintenance is light but not zero. Rake when the mood takes you. Lift fallen leaves with a soft rake or a leaf blower on its lowest setting rather than a hose. Top up the gravel each spring, and check the edging has not lifted. Keep the courtyard drain and any gully clear of stone, because blocked drainage is the one fault that will ruin a pebble garden faster than anything else.
Two practical notes. In flats, leasehold properties, listed buildings and conservation areas, check with your freeholder or local planning authority before changing surfaces or drainage — the rules vary and it is a tedious thing to undo. And if you are adding a water feature, lighting or any electrical work, use a qualified electrician rather than a plug-in extension lead through a door.
Get those things right and you end up with a courtyard that asks almost nothing of you: no mowing, no deadheading, no watering cans in August. Just stone, a few plants, and the quiet satisfaction of a fresh set of lines after rain.
