Choose your location carefully

When choosing a location take a careful look around your garden. The location should be a safe distance from your house and any other buildings or overhanging trees. The ground should be level and be free of any underground pipes or wiring.

Clear the area and set your foundations

Once you have an area picked out you’ll need to clear the area of all obstructions and begin digging for the foundation. It’s important that you make this both deep and solid as your fireplace will be very heavy. The concrete base should be at least 8” thick.

Build a base and firebox

With your foundations set you’ll next need to set a base for the fireplace. A 4” solid block should be enough. Using your firebricks then begin to build the firebox. This can be built to whichever size you choose. Just make sure it’s kept level and square.

Build the throat

Once the firebox is completed and the motor set you’ll need to start on the ‘throat’ by building the blocks around it. This will involve a cobbling technique of overhanging the bricks so they overstep each other. Continue until you have reduced the opening to the size of your flue liner.

Build the flue

Set your first liner in a bed of mortar and slide a flue block over it. Repeat until you have the height you want.


Now comes the fun part. Begin setting your chosen stones around the fireplace, stacking it based on your own chosen style. Fill the spaces between each stone with mortar. If your using bricks rather than stone, use the grindstone to cut each piece to size.

That’s roughly it. This is a project that allows you a lot of creativity so do some research to find a style that suits you.
