Courtyard and Small Garden Design: How to Make Every Square Metre Count
A courtyard or small garden is not a compromise. In London and the South East, some of the most striking outdoor spaces we design at Soil Sisters are under 30 square metres. The constraints force sharper decisions about materials, planting and layout, and the results can be more considered than anything you get in a larger plot.
Whether you have a narrow side return, a walled courtyard off the kitchen, or a compact urban garden behind a terrace house, this guide covers the practical design principles, plant choices, costs and materials that turn a small outdoor space into something genuinely worth using.
Assessing Your Space Before You Design
The first thing we do on any courtyard project is spend time understanding the space itself. Before you buy a single paving slab or plant, you need to know three things:
Sun path. Track where direct sunlight falls at 9am, noon and 3pm across a full week. Most enclosed courtyards in London and the South East get 2 to 4 hours of direct sun per day. South-facing courtyards may see 5 to 6 hours in summer but almost nothing in December. This dictates everything from plant selection to where you position seating.
For dedicated patio design services in London, including full pricing and material guidance, see our patio design page.
Wind patterns. Walls shelter courtyards from open wind, but narrow passages between buildings can create wind tunnels. A gust forced through a 1-metre gap hits harder than open-field wind. Note where draughts come from and plan screening accordingly.
Drainage. Small walled spaces hold moisture. Check whether water pools after rain, and whether you have access to a drain or soakaway. Poor drainage limits your paving options and plant choices.
Design Principles for Small Gardens
Designing a small garden well is about restraint. Fewer materials, fewer plant species, and fewer "features" will almost always produce a better result than cramming everything in. Here is what actually works.
Use vertical space aggressively
In a courtyard, the walls are your biggest asset. Climbing plants on tensioned wire systems (stainless steel at roughly £15 per metre installed), living wall panels, wall-mounted planters and hanging baskets all add greenery without eating floor space. A single star jasmine (Trachelospermum jasminoides) trained on a south-facing wall will cover 3 to 4 square metres in two to three years and scent the entire space in June.
Limit your material palette
Two paving materials maximum. One type of timber or metal for raised beds, planters and screening. One colour family for pots. Consistency across a small space makes it feel larger and more deliberate. Porcelain paving tiles are popular for courtyards because they resist moss and frost, typically costing £30 to £60 per square metre supplied.
Scale furniture to the space
A bistro set (small round table and two chairs) takes up roughly 1 x 1 metre. A standard 6-seat dining set needs at least 3 x 2 metres with chair clearance. In a courtyard under 20 square metres, built-in bench seating along one wall with a narrow table is usually a better use of space than freestanding furniture.
Planting for Courtyard Gardens in the UK
Shade is the defining challenge — and if your courtyard is also north-facing, our north-facing garden design ideas cover exactly this scenario. Most courtyard walls are at least 2 metres high, and many are surrounded by 3-storey buildings. That means you are designing for part shade to full shade across most of the space, with perhaps a single sunny corner.
Shade-tolerant plants that thrive in courtyards
These are the reliable performers we use regularly in courtyard designs across Kent, Surrey and London:
- Fatsia japonica (Japanese aralia). Bold architectural leaves, evergreen, thrives in deep shade. Reaches 2 to 3 metres. Around £15 to £25 for a 3-litre pot.
- Hakonechloa macra (Japanese forest grass). Graceful arching habit, golden-green foliage, works beautifully in containers. £8 to £12 per plant.
- Hydrangea anomala petiolaris (climbing hydrangea). Self-clinging climber for shady walls, white lacecap flowers in June. Slow to establish but covers 6+ square metres once mature.
- Dryopteris erythrosora (autumn fern). Coppery new fronds, evergreen in mild winters, perfect for underplanting. £6 to £10.
- Sarcococca confusa (Christmas box). Small, glossy evergreen shrub with powerfully fragrant white flowers in January and February. Brilliant near a door. £8 to £15.
- Trachelospermum jasminoides (star jasmine). Needs at least 3 hours of sun. Evergreen climber, intensely fragrant white flowers in summer. £15 to £25 for a 2-litre plant.
For the sunny corner (if you have one), try Lavandula angustifolia, Salvia nemorosa, or a potted olive tree (Olea europaea). All handle the reflected heat from courtyard walls well.
Container planting tips
Containers are essential in courtyard gardens where built-in beds are not practical. Use the largest pots you can fit. A 40cm pot dries out in a day during summer, while a 60cm pot holds moisture for two to three days. Group containers in odd numbers (3 or 5) and vary heights for a more natural feel. Self-watering pots or an automated drip irrigation system (from about £40 for a basic kit) will save you time and keep plants alive through dry spells.
Water Features for Small Spaces
The sound of running water makes a courtyard feel more enclosed and private, and masks urban background noise. You do not need a pond. A self-contained wall-mounted water feature starts at around £80 and requires only a standard outdoor power socket. Bowl features sit on the ground and recirculate water through a pump. Either option adds a focal point without demanding more than 0.5 square metres of space.

If you want something more bespoke, a corten steel water blade or a stone trough with a spout can be designed into the wall during the build phase. Expect to pay £300 to £800 installed for a custom courtyard water feature.
Lighting a Courtyard Garden
A well-lit courtyard is usable from March through to November in the South East. Without lighting, you lose the space after 5pm in winter. The key rules:
- Warm white (2700K) only. Cool white LEDs (4000K+) make enclosed spaces feel clinical. Warm white mimics candlelight and makes brick, stone and foliage look their best.
- Uplight trees and feature plants. A single LED spike light (£15 to £30) aimed up through a Fatsia or tree fern creates dramatic shadows on the walls.
- Festoon or string lights at 2.5m height from wall to wall create an ambient canopy of light. Expect to pay £20 to £50 for a quality outdoor set.
- Recessed step and wall-wash lights (£20 to £40 each) define paths and edges without cluttering the space.
Budget around £500 to £1,500 for a full courtyard lighting scheme installed by an electrician, depending on the number of circuits and features. For more detail, see our guide to garden lighting design.
Mirrors and Visual Tricks
An outdoor mirror on a courtyard wall genuinely doubles the perceived depth of the space. Use a properly framed exterior mirror (acrylic is safer than glass in exposed positions) and position it to reflect planting or sky rather than the back of a building. Partial concealment behind climbing plants makes the illusion more convincing. Outdoor mirrors cost from £40 to £200 depending on size and frame material.
How Much Does Courtyard Garden Design Cost?
Costs vary enormously depending on materials and complexity, but here are realistic 2025/2026 figures for the South East:
| Item | Small courtyard (10-15 sqm) | Medium courtyard (15-30 sqm) |
|---|---|---|
| Design fee | £800 - £1,500 | £1,200 - £2,500 |
| Porcelain paving (supplied and laid) | £1,000 - £2,500 | £2,000 - £5,000 |
| Raised beds / planters | £400 - £1,200 | £800 - £2,500 |
| Planting (supplied and planted) | £300 - £800 | £600 - £1,500 |
| Lighting scheme | £500 - £1,200 | £800 - £1,500 |
| Water feature | £80 - £500 | £300 - £800 |
| Total estimate | £3,000 - £7,500 | £5,500 - £14,000 |

Small Garden Design Ideas That Actually Work
The side return
A narrow passage beside a terraced or semi-detached house, typically 1 to 1.5 metres wide. Use it as a green corridor: a single line of tall, narrow planters with bamboo (Fargesia murielae for a non-invasive clumper), underlit with recessed ground lights. Add a simple water rill running the length if the budget allows.
The basement courtyard
Usually the most challenging because light levels are lowest. White or pale-painted walls increase reflected light by up to 70%. Ferns, hostas and Epimedium groundcover are your main planting toolkit. A large mirror on the back wall, partially obscured by foliage, opens the space dramatically.
The urban back garden under 30 sqm
Even a 5 x 5 metre garden can include a dining zone, a planting area and a water feature if the layout is disciplined. We typically split these spaces into two or three zones using changes in level (even a single step up creates definition) or different paving materials. See our modern small garden ideas for more on zoning compact spaces.

Frequently Asked Questions
How do I make a small courtyard garden look bigger?
Three things make the biggest difference: painting walls in a pale colour (white or light stone increases reflected light by up to 70%), placing an outdoor mirror to double perceived depth, and keeping the paving pattern simple and continuous rather than using multiple materials that break the space up visually.
What plants grow well in a shaded courtyard?
Ferns (especially Dryopteris and Polystichum), hostas, Fatsia japonica, Sarcococca (for winter scent), climbing hydrangea and Hakonechloa macra all perform well in part to full shade. For a sunny corner, try lavender, salvia or a potted olive.
How much does it cost to design a small courtyard garden?
A professional design for a small courtyard (10 to 15 sqm) typically costs £800 to £1,500 in the South East. The full build including paving, planting, lighting and a water feature ranges from £3,000 to £7,500 for a small courtyard and £5,500 to £14,000 for a medium-sized space (15 to 30 sqm).
Can I have a water feature in a small garden?
Yes. Self-contained wall-mounted or bowl water features start at about £80, need only a power socket, and take up less than half a square metre. They recirculate water through a built-in pump, so there is no plumbing to worry about.
Do I need planning permission for a courtyard garden?
Generally no, provided you are not building structures over 2.5 metres high or covering more than half the original garden area with hard surfacing (which can affect drainage regulations). If you are in a conservation area, check with your local authority before painting boundary walls or installing structures. See our guide to garden planning permission for the full picture.
