How To Build A Stone Fire Pit How To Build A Stone Fire Pit
The addition of a stone fire pit to a yard can be accomplished with a few tools, materials and of course labor. A fire pit can provide a gathering point for families and friends.
Firepit Safety & Legality
Always check with the local Fire Marshall to be certain that it is legal to have a fire pit, and to comply with any guidelines for placing and building one. In general, pits should not be placed near ignition sources such as fuel tanks, near to homes and other structures, and it is a good idea to have a source of water near-by, such as an outdoor hose.

Step 1-Lay Out The Pit
Once the location is settled, drive the wooden stake into the ground where you want the center of the pit to be. Tie one end of the string to the stake. The string length should be one half of the diameter of the desired pit. If you want a 4 foot diameter pit, measure a 2 foot length of string from the post. If you are going to build the pit with a fire ring that holds a cooking grate, be certain that you design the pit so that the ring fits just inside the blocks.
Once the size is determined, cut the string to the proper length. Hold the can of landscape spray paint at the end of the string, with the nozzle facing the ground. Walk in a circle with the string taught and spray the paint to mark the outside border of the pit.
Step 2-Prepare The Base
Dig the outlined pit to the depth of 10 to 12 inches. Pour in 4 inches of gravel and level it with a piece of 2 by 4 inch board or carpenter's level. Cover with 4 inches of sand and level in the same way. This deep base will provide for adequate water drainage. Lay the first layer of landscape blocks around the perimeter of the pit. The blocks will sit below the soil surface, but extend above it. The bottom layer of blocks should touch each other. Use the level to be certain that the block tops are level, and level with each other. Fill the spaces between the blocks with sand to create a solid foundation.
Step 3-Build Walls To Desired Height
Continue to stack the landscape blocks, arranging them so the seams between blocks are staggered. Any small gaps between blocks will allow the fire to draw oxygen to burn. Three to four layers of blocks will be sufficient and not so high that the pit is difficult to clean.
A fire ring with grate may purchased from a farm and garden store or other supplier. It is easier to set the ring in the pit before setting the top layer of blocks.
