Whether you want to create a space for entertaining or just create a comfortable place for family and friends to gather, think about building a fire pit! If you’re not sure how, don’t worry—we’ve got this. Keep reading for a guide on how to make your own DIY fire pit.

Step 1: Choose the Location

  • Choose a location that is level and dry, away from trees, buildings and combustible materials.
  • Choose a location away from your house and neighbor’s house.

Step 2: Build the Fire Pit Frame

  • Prepare the ground by removing any grass, rocks or other debris from the area where you’ll be building your fire pit.
  • Make sure that the ground is level.
  • Lay out a frame using level stakes and string to trace a square around your intended fire pit area.
  • Use a level when measuring to make sure your frame is square; otherwise, it may not fit together properly later on.

Step 3: Lay the First Course of Blocks

To lay the first course of blocks, make sure that they are level. To do this, place a spirit level on top of one block and make sure that it is parallel to the ground. If not, use a spirit level to adjust it until it is perfectly level.

Once you have laid down your first course of blocks in this way, you can begin to add more retaining wall blocks in an alternating pattern between each layer. Again, use your measuring tape and try to make them fit together as tightly as possible so that you don’t have large gaps between them which will result in water seeping through over time!

Step 4: Add a Cap for the First Course

The cap for the first course of blocks should be installed flush with the ground, but leave an inch or so between it and the second course. The second cap will be installed at a height equal to that of the first, leaving an inch or so between it and the third. Thread your rebar through each section, starting with the bottom one and working up until you’re done. If you have any trouble, some extra mortar will come in handy (and can be used to fill gaps).

Step 5: Lay the Second Course Cap Side Up

The second course cap side up. Lay the cap side up. This will ensure that it is level, square and centered. Make sure it is plumb and straight as well.

Step 6: Lay the Third and Final Course of Blocks

Lay the third and final course of blocks, which will be laid side down. This will ensure that they’re level with each other, just as they were in the first course.

When you lay this layer of retaining wall blocks, use the same block size as you did with the first one. Lay them in an identical pattern to what you did before so that it looks neat and tidy from a distance.

You can use a level or spirit level to make sure each block is level with its neighbor and also with the ground or lawn beneath it.

Step 7: Finish the Third and Final Layer with a Cap

The third and final layer will have a cap on top of it. Lay this side up, so that the top of your retaining wall is flat.
