How high can a single brick wall be? It’s a simple enough question, and one most of us have thought at some point. Of course, there are brick structures that go up several floors, but are they all one wall or built into sections? 

If you look online, you’ll see a mixture of answers ranging from a couple of feet tall for garden brick walls to around five feet tall for things like gates or a tool shed in the backyard.

But, in general, it’s probably best to keep a single brick wall, also called a single skin wall, to around 1 meter high, or between 3 and 4 feet. 

Limiting it to that height reduces the risk of structural instabilities. If you’re only using a single skin, the weaker your wall becomes, the higher you go.

Any mistakes in the build quality will affect its ability to keep standing. In addition, bad weather, weight-bearing, and other external factors can weaken the wall and cause it to collapse. 

Make a single skin wall that lasts by sticking to height recommendations and building your wall correctly.

    Go deep, at least a foot or a foot and a half. This should be sufficient for a single brick wall as tall as three or four feet.


  2. The Mortar – You can purchase pre-mixed mortar or mortar you mix by yourself.Mixing is cheaper and isn’t all that difficult. It’s also an excellent skill to learn, so give it a try if you’re inclined. Put a healthy layer down in the trench after you mix the mortar according to instructions.

    Then, start laying your bricks! Put them on slowly, one at a time. Almost every brick has what are called “frogs” on them. These are small indentations that tell you that side should be facing up.

    The mortar goes into the space and holds the bricks together better.


  3. Building Vertically – As you complete your line of bricks, it’s time to start thinking about building upward.Lay the mortar on top of your bricks and stack bricks on as you go. Please do your best to make sure each brick and layer have an equal amount of mortar on them.

    It will help your finished project look uniform.


  4. Go Slowly – Don’t rush. Taking your time reduces the risk of errors that ruin your brick wall.Take your time and examine each brick as you go. Make minor adjustments to get things the way you want them. One thing you may want to consider is by capping bricks.
