Quick Answer
Building a garden wall in the UK costs £100–£180/m² for concrete block, £180–£250/m² for single-skin brick, £200–£320/m² for double-skin brick, and £300–£600/m² for dry-stone. A typical 5-metre boundary wall costs £1,500–£6,000 depending on height and material in 2026.
A garden wall can provide privacy, security, and a clean boundary to your property. Whether you're replacing a crumbling old wall, building a new boundary, or adding a decorative retaining wall to level a sloped garden, getting accurate costs before approaching a bricklayer or builder is essential.
Garden wall costs in the UK are primarily driven by the wall type and height, the length of the run, material choice, and whether footings (foundations) are needed. In 2026, labour costs for bricklayers remain high due to ongoing skills shortages in the construction trades — getting multiple quotes is more important than ever.

Garden Wall Types and Costs
| Wall Type | Cost per m² | Best For | Durability |
|---|---|---|---|
| Concrete block wall (painted/rendered) | £100 – £180/m² | Functional boundaries, render finish | 50+ years |
| Single-skin brick (102mm) | £180 – £250/m² | Low garden walls up to 1m, decorative | 50+ years |
| Double-skin brick (215mm) | £200 – £320/m² | Boundary walls over 1m, structural | 100+ years |
| Reclaimed brick wall | £220 – £350/m² | Period properties, character finish | 100+ years |
| Dry-stone wall | £300 – £600/m² | Rural properties, Cotswolds/Peak District style | Decades (needs repointing) |
| Reconstituted stone | £200 – £350/m² | Stone look with easier installation | 40–60 years |
| Sleeper retaining wall | £150 – £300/m² | Retaining sloped ground, garden levels | 15–25 years (oak longer) |
Double-skin brickwork (also called cavity or solid 215mm brickwork) is the standard for any wall above 1 metre. It's structurally sound, looks attractive, and when built properly will last a century or more. Single-skin brickwork is fine for low decorative walls and raised beds but is not suitable for tall boundary walls which need to withstand wind loading.
Dry-stone walls are most common in rural areas — particularly the Yorkshire Dales, Peak District, Lake District, and Cotswolds — where they form a traditional part of the landscape. Building a genuine dry-stone wall is a highly skilled craft and the cost reflects that. Restoration of an existing dry-stone wall is usually less expensive than building from scratch.
Cost by Typical Wall Lengths and Heights
Costs for a typical double-skin brick garden wall (including foundations and coping) at various lengths and heights:
| Wall Dimensions | Block Wall | Single-Skin Brick | Double-Skin Brick |
|---|---|---|---|
| 5m long × 1m high | £500 – £900 | £900 – £1,250 | £1,000 – £1,600 |
| 5m long × 1.8m high | £900 – £1,600 | £1,600 – £2,250 | £1,800 – £2,880 |
| 10m long × 1m high | £1,000 – £1,800 | £1,800 – £2,500 | £2,000 – £3,200 |
| 10m long × 1.8m high | £1,800 – £3,200 | £3,200 – £4,500 | £3,600 – £5,760 |
| 20m long × 1.8m high | £3,600 – £6,400 | £6,400 – £9,000 | £7,200 – £11,520 |
💡 Tip
Foundations (footings) are included in the above prices and are non-negotiable — a wall without proper concrete strip footings will move and crack within a few years. Typical footings add 15–20% to the cost but are essential for a lasting result.
What Affects the Cost of a Garden Wall
| Factor | Impact | Notes |
|---|---|---|
| Wall height | Very high | Taller walls need more materials, deeper foundations, possibly engineer input |
| Brick type | High | Facing bricks vs commons — £300–£600/1,000 range |
| Demolition of old wall | Medium | Removing existing wall adds £200–£600 |
| Access | Medium | Tight access for mixer/materials increases labour time |
| Ground conditions | Medium | Soft ground needs deeper footings — adds cost |
| Coping type | Low-medium | Bullnose coping vs concrete vs saddle — £10–£40 per metre |
| Location | Medium | London rates 20–30% higher |
| Piers / pillars | Medium | Structural piers every 3m add £150–£300 each |
Planning Permission for Garden Walls
In England, under permitted development rules, you can build a garden wall up to the following heights without planning permission:
- Up to 1 metre high adjacent to a road or highway (including the pavement side of your front garden)
- Up to 2 metres high anywhere else (rear and side boundaries not adjacent to a road)
- Within a conservation area or if the property is listed, permitted development rights are more restricted — walls over 1m in a conservation area may need consent
Any wall that forms part of a structure requiring its own building regulations (e.g., a basement retaining wall) will also need Building Regulations approval regardless of height. Read our guide on planning permission for home improvements for a broader overview of what requires consent.
Party Wall Agreements and Boundary Walls
If you're building a wall on or close to the boundary between your property and a neighbour's, the Party Wall Act 1996 may apply. You'll need to serve notice on your neighbour before starting work if:
- You're building a new wall along a boundary line (party fence wall)
- You're demolishing or rebuilding an existing shared boundary wall
- Excavation works are within 3–6 metres of a neighbouring building
For full details on when a party wall agreement is needed and what it costs, read our guide on party wall agreements in the UK. For understanding all the rules around what you can build without planning permission, see our article on permitted development rules in the UK.

Frequently Asked Questions
How long does it take to build a garden wall?+
A typical 5-metre garden wall takes 2–4 days to complete including footings (which need to set for 24–48 hours before brickwork begins). A longer wall (10–20m) takes 5–10 days. Dry-stone walls take longer due to the skill involved in selecting and placing each stone.
Do I need a structural engineer for a garden wall?+
For walls up to 1.8m built on stable ground with standard footings, a structural engineer is not usually required. For taller walls, retaining walls holding back significant soil loads, or walls on soft ground, a structural engineer should specify the foundation depth and reinforcement requirements.
Can I build a garden wall myself?+
Bricklaying to a consistent standard is a skilled trade. While a simple, low single-skin wall is within reach of a patient DIYer with some practice, anything taller or more complex — especially a boundary wall that needs to look neat and last decades — is best left to a professional bricklayer.
How much does it cost to repair a garden wall?+
Repointing a garden wall costs £20–£40/m². Rebuilding a collapsed section from scratch costs £180–£320/m². Replacing damaged coping costs £10–£40/linear metre. Always address pointing issues early — deteriorated mortar leads to water infiltration and frost damage that accelerates structural failure.
What is the best type of wall for privacy?+
A double-skin brick wall at 1.8m is the most effective privacy solution and looks attractive. If budget is a concern, concrete blocks rendered and painted can achieve the same privacy height for less cost. Timber close-board fencing (not a wall) is even cheaper but far less durable in the long term.
