Gardens are becoming more multi-functional as people start to use them more as an additional room to their houses rather than just somewhere for a flower bed.

Fitting a DIY Firepit

The fire pit I’m creating is going to be a circular design. I find circular focal points in gardens encourage people to sit around them and connect. You can create any shape you desire but I find circles are the most relaxed and really help connect with any garden layout. Squares and rectangles can be a bit formal and if you get the proportions wrong can look uneven. I’m installing this in the Exploding Atom Garden if you want to know more on this concept garden then read the design guide here.

Step 1: Find the position of where you want to fit your fire pit. Ensuring its not underneath any overhanging trees of wooden structures. I like to place mine centrally in a lawn which gives easy access all around and draws your eye to it as a focal point. Use string to find the central point of your fire pit area. Put a cane in the lawn to mark the center.

Step 2: Measure the diameter of your fire bowl or steel bowl. This is the width. You then need to add 30cm-50cm as your final diameter. This to allow for the fire pits surrounding rocks and ensure its a safe distance away from the fire you whilst enjoying it!

Step 3: Tie a piece of string to the central cane and measure out the radius ie half the total diameter. Then tie your tent peg to this string. You can then swivel the string around the cane to mark out your circle. I use additional canes to map out the circle in the turf

Step 4: Cut out the turf from your marked out circle. I use a sharp spade and cut the turf into strips before lifting them. Aim to lift 1-1.5inches of turf off. This turf can also be recycled by stacking it grass side down so it breaks down into gorgeous garden soil!

Step 5: Use a rake to level out the exposed circle. Remove any large rocks or debris you’ve uncovered.

Step 6: If using an edging strip like metal or plastic then using your sharp spade cut around the circle. Ready for you to fit your edge strip. If you’re using bricks to edge it you’ll need to dig a small trench and then bed these into either sand or cement.

Step 7: Add your weed membrane, to stop any weeds growing back up and then add 1-1.5 inches of gravel or hardcore into the circle. Use a rake to spread it out and then compact if with your feet. This is now the fireproof base to protect the ground and also you from the fire pits potential heat!

Step 8: This is the fun bit. Start arranging your rockery stone, concrete or reclaimed building materials into a circle which the fire bowl will sit. Use bricks to create a flat level area in the middle where the base of the bowl or dustbin lid can sit. Then with a piece of wood and spirit level make sure its level.

Step 9: Place your bowl in the middle and then using decorate gravel or chippings dress around the circle any gaps that there maybe. This decorative step will start to make your fire pit look amazing. So take your time and use any recycled materials you can as long as they are heat resistant. Broken roof tiles or broken terracotta pots can look great too!

DIY Fire Pit advice

It goes without saying always make sure you are sensible with fire safety and never leave the fire pit unattended. If you’re lifting heavy objects make sure you get help from someone. Bend when you lift. Take your time. Always say please and thank you, that kind of stuff!

A fire pit can add a real wow factor to the garden. It’s also achievable using recycled materials saving them from going to landfill. Whether you choose a fancy corten steel bowl or a metal dustbin lid the same effect can be achieved on different budgets or garden sizes. If you have trees on your property then any tree prunings or fallen branches can be used in the fire bowl. Meaning its a solution that can be a really low carbon footprint design project!
