How Much Does it Cost to Build a Garden Wall?

We recently had new fence panels installed in our garden (see fence panel installation prices here) but we did seriously consider having a wall constructed instead. Check out this page to see how much a wall would’ve cost us.

We will provide a fully costed example for a double-skin garden wall. We can also point you in the right direction so you can get a written quote for your garden wall project.

On this page you’ll discover:

  • Guide prices based on our experience.
  • A detailed breakdown of the costs.
  • Advice on what type of wall is best (double vs single skin).
  • Extra costs to consider and tips on how to save money.

Reminder: This is just one of the dozens of helpful price guides we have on our website. See our full price list here.


Cost to build a brick wall

For the cost example shown on this page, we assume the following:

Double skin wall 5 metres in length and 1.2 metres in height

For the avoidance of doubt; a single skin wall is approximately 100mm wide and a double skin 225mm wide.

What Thickness is Best?

For walls up to 500mm in height, you can build a single skin wall with multiple piers for added stability.

For walls above 500mm in height, the thickness should ideally be double skinned, with piers for added strength.

Retaining walls above 900mm in height should be designed by a structural engineer. They will take into account the location of the property and potential wind conditions etc.

Any wall above 1.8metres should also be designed by an engineer for safety reasons.

Information about garden wall thicknessHow May Piers/Pillars?

This depends on the height, width and length of the wall.

For a 5 metre wall, one pier would usually be constructed at each end and another in the centre.

Piers should also be constructed on either side of a gate.

Below is a list of all the key materials used in the construction of a 5m x 1.2m double skin garden wall.

Wall/pier coping stones£45.00
DPC - damp proof course£10.00

What About Labour Costs?

A wall of this size would normally take around three days.

Day 1 – Dig and lay foundations and allow to dry.

Day 2 – Start bricklaying.

Day 3 – Finish bricklaying and finish off with concrete coping stones on top.

The above guide assumes that two workers are on the project, that’s one labourer and one skilled bricklayer.

If an existing wall or fence needs to be removed or if there’s substantial excavation work required, then add an extra day to the project.

Labour 3 x days (bricklayer)£450.00
Labour 3 x days (labourer)£225.00
VAT on labour and profits£200.00

How to Save Money

As you can see from the table above, we have made an allowance for VAT and a guide to profit margins for a small business.

Don’t forget; if you choose a smaller business such as a “one-man” type trader to do this type of work, then you won’t be paying as much for profits if any at all. This is because many bricklayers charge just enough to cover their wages and overheads.

Also, if your chosen business is operating below the VAT registration threshold then they won’t be charging you this tax, (more info about how you can legally avoid paying this tax here).

We have created a separate guide to tradesperson’s “day rates”. Click the button below to check it out:

See Tradesperson's Day Rates

Our price is for a double skin wall as we feel that is best for a wall of this size (5m x 1.2m) but if your wall is smaller, then you could make a saving by building a single skin wall.

The bricks we chose weren’t the cheapest, a quick look on Ebay and you’ll find plenty of bricks priced at £150 per 500.

Extra Costs to Consider

If you have a lot of earth that needs excavating or an old wall or fence to be removed then you’ll need to pay for waste disposal or skip hire.

See how much skip hire costs here.

Also, our price guide on this page assumes mid-range, mid-quality facing bricks. If you want to use decorative garden bricks, perhaps to match a patio then expect to pay more for the materials.

If your wall is a retaining wall, then it will need deeper and wider foundations. In many cases, the base of the wall will also be wider and there will be more piers/pillars.  This means more bricks and time is required. Also, one side of the retaining wall will be shielded from excess moisture by either waterproof tanking, a waterproof felt layer or both.

Further down the page, you’ll find some handy calculators so you can work out how many bricks, sand, cement and other materials are needed to construct your wall. It’s then just a case of finding a supplier online and getting a price. Many suppliers now offer instant pricing online.

This website has a great calculator so you can work out how much sand, cement and how many bricks are required for either a single or double skin wall:

See calculator here

Jewsons also have a brick calculator, you'll need to make an extra allowance for pillars/piers and double the figure for double skin walls.

WhatPrice suggest a price of £800 for a brick wall 5m x 2m. However we can't see how this would work as even the cheapest bricks would cost £350 and cheapest non branded sand/cement £150. So that leaves £300 for two people working three days. That would mean working below the minimum wage.
