Narrow courtyard with a timber boardwalk over pebble and a waterfall
Two decisions hold this courtyard together and neither is decorative. The first is the walkway: timber boards laid crosswise with river pebble between them, which in a narrow shaded courtyard has to be resolved knowing that wood goes slippery once algae forms on it. The second is the bamboo, which sits in planters rather than in the ground. Containing it from the start is what stops it coming up through the gravel and under the boardwalk within a few years.

Rhizome barrier for bamboo
A rigid high-density polyethylene sheet, buried around the planting to stop the rhizomes advancing. The two figures that matter are depth and thickness: it wants burying sixty or seventy centimetres deep with a couple of fingers standing proud of the soil, because a rhizome reaching the barrier climbs and jumps it if it can't see the top. Set it leaning outward with the overlap closed by a joining profile, not simply lapped.
Grit adhesive strips or a varnish with anti-slip additive, for the walking area of a deck. In a narrow damp courtyard it's the difference between a walkway and a slide, and there's no need to treat the whole surface: the central strip you walk on is enough. Strips are visible, so choose the closest colour to the timber; loaded varnish shows less but needs reapplying every one or two seasons.
A product that removes the green film from timber and pebble without scrubbing or a pressure washer. On a walkway use it before the algae is visible, because by the time you can see it the surface has been slippery for a while. Avoid high-pressure washing on timber: it raises the grain and leaves the board rougher, which grips better short term and holds more dirt in the medium term.
Height-adjustable plastic feet supporting the battens, instead of bedding the deck onto the ground. They solve two things at once: they leave a ventilation cavity under the boards, which is what stops them rotting from below, and they let you level over a sloping floor without breaking anything up. Choose the self-levelling head version if the slab has a drainage fall, which it nearly always does.
Fargesia or a similar clumping species, growing as a compact stool without sending out running rhizomes. It's the alternative to a barrier when you want to plant straight into the ground without the bamboo becoming a problem five years out. It grows a little slower and doesn't reach the height of a running bamboo, so for a tall screen allow more time or plant mature specimens.
The boards are set apart with pebble between them, and the gap has to be narrow. Over three or four centimetres it catches a heel and the stone works its way in: the joint exists so the pebble shows, not so a foot fits.
The walkway sits on battens, clear of the ground rather than resting directly on the stone. With no cavity underneath the timber can't dry on its lower face, and in a narrow shaded courtyard that's what rots it from below while it still looks new on top.
The bamboo is in planters and not in the ground, and that isn't an aesthetic decision. A running species in a courtyard like this comes up through the gravel and under the paving within a few years: containing it from the start costs a fraction of removing it later.
The water falls across a wide face and the trough catching it is narrow. Let it project past both ends of the face, because the curtain spreads as it falls and what escapes at the sides is exactly what wets the pebble and gradually scales it.
The ceiling downlights sit in the side overhang and not in the centre, which is open to the sky. That's what gives you overhead light in an uncovered courtyard: the installation stays protected under the soffit and the centre is left clear for the rain.
FAQ
Does a timber deck get slippery in a courtyard?
In time yes, and in a narrow courtyard more than anywhere. What's slippery isn't the wood but the film of algae that forms when the surface never quite dries, and between two high walls with a waterfall beside it that film appears fast. Three things prevent it: a grooved profile rather than a smooth one, a ventilation cavity underneath so the board dries on both faces, and cleaning before the algae is visible rather than after. If the deck is already down and slippery, anti-slip strips on the boards you walk on solve it.
Does ground-planted bamboo need containing?
If it's a running species, always. Running bamboos send out rhizomes that travel metres underground and emerge where you don't expect them: in a narrow courtyard they come up through the gravel, in the walkway's joints and even on the far side of a party wall. Containment means a rigid polyethylene barrier buried sixty or seventy centimetres deep, with its top edge standing a couple of fingers proud so the rhizome can't jump it. The simpler alternative is the one in this photo: plant into closed planters. Or choose a clumping species outright, which grows as a compact stool and doesn't run.
Can a courtyard be left open in the middle and covered at the sides?
It's one of the most useful solutions in a narrow courtyard, because you keep the sky without keeping everything the sky brings. The side overhang protects the walls, allows recessed lighting in a space that's otherwise open to the weather, and gives a strip of floor that stays dry. In exchange you have to resolve the water in the middle: it genuinely rains there, so that stretch needs a drain or a permeable floor, and the overhang's edge wants a drip groove so water doesn't run back down the wall face and stain it.
