Garden Walls - Costs & Guides for UK Homeowners
A new garden wall typically costs between £100 and £300 per linear metre, depending on the material and height. Whether you want a brick boundary wall, a natural stone feature, or a retaining wall to hold back a slope, getting the foundations right is the single most important thing. Check the Planning Portal walls guidance for height limits and planning rules.

Types of garden wall
The material you choose affects the cost, appearance, and how long the wall lasts. Here are the main options for UK gardens.
Brick wall
The most common choice for garden boundaries, and for good reason. Hundreds of colours and textures to match your house. A single-skin wall (half-brick thick) works for walls up to about 600mm. Go taller and you will need double-skin with piers at regular intervals.
Natural stone wall
Beautiful, but you pay for it. Popular in rural areas and conservation zones. Can be built dry (no mortar) or with mortar joints. Dry stone walling is a proper craft, and finding someone good at it will cost you more again.
Block wall with render
Concrete blocks are the cheapest structural option. They look rough on their own, so most people render and paint them. Done well, the finished result looks clean and modern. The quality of the render job makes or breaks it.
Retaining wall
Built to hold back earth on a sloped site. These are structural walls and need proper engineering, especially above 1 metre high. Heavier foundations, drainage behind the wall to stop water pressure building up. Not a DIY job under any circumstances.
Things to think about before you build
Foundations are everything
A garden wall without proper foundations will crack and lean within a few years. The footing should be at least twice the width of the wall and deep enough to reach solid ground, typically 300mm to 600mm. Clay soil? Go deeper. Any bricklayer who skimps on foundations is telling you everything you need to know about their work.
Planning permission and boundary rules
Walls under 2 metres do not usually need planning permission, dropping to 1 metre if next to a highway. The Planning Portal has a dedicated guide to fences, gates, and garden walls at planningportal.co.uk. If the wall sits on a shared boundary, the Party Wall Act may apply, which means you need to notify your neighbour at least a month before starting. Listed buildings and conservation areas have stricter rules.
Coping stones matter more than you think
A coping stone sits on top of the wall to stop rain soaking into the brickwork. Skip it and water gets into the mortar joints, freezes in winter, and the wall deteriorates years earlier than it should. Budget £15 to £40 per metre. Cheap insurance.
Match the bricks to your house
If the wall is visible from the front, matching the bricks to your house makes a real difference to kerb appeal. Take a sample brick to the merchants and ask them to find a match. Reclaimed bricks look more authentic but they cost more and good ones are getting harder to find.
Get at least three quotes
Bricklaying prices vary considerably between tradespeople, and so does what is included - some quote for the wall only, others include foundations, coping stones, and clearing up. Get at least three written quotes for the same specification so you can compare like for like. It is the simplest way to make sure you are paying a fair price.

Common questions about garden walls
How much does a garden wall cost per metre?
A garden wall typically costs between £100 and £300 per linear metre, depending on height, material, and whether it needs proper foundations. A single-skin brick wall at 1 metre high costs £120 to £200 per metre. Double-skin brick runs £200 to £350 per metre. Natural stone is the most expensive at £180 to £350 per metre.
Do I need planning permission for a garden wall?
In most cases, no. Garden walls under 2 metres high do not usually need planning permission. If the wall is next to a highway or public footpath, the limit drops to 1 metre. If your property is listed or in a conservation area, you may need consent regardless of height. Always check with your local council if you are unsure.
What is the Party Wall Act?
The Party Wall etc. Act 1996 applies in England and Wales when you are building a wall on or close to a boundary with a neighbour. If the wall sits directly on the boundary line, you must serve a party wall notice on your neighbour at least one month before starting work. If the wall is entirely on your land but within 3 metres of a neighbouring structure, you may still need to give notice depending on the foundation depth.
How long does a brick garden wall last?
A well-built brick garden wall with proper foundations and coping stones can last 50 years or more. Very little maintenance needed. The most common cause of failure is poor foundations, which lead to cracking and leaning. Frost damage to the bricks themselves is rare with modern engineering bricks, though soft reclaimed bricks are more vulnerable.
Can I build a garden wall myself?
A low decorative wall under 600mm is a realistic DIY project if you have some bricklaying experience. Anything taller needs proper foundations, correct bonding patterns, and piers at regular intervals to stop it toppling. A badly built wall is a genuine safety hazard. For anything structural or above waist height, get a bricklayer in.
