DIY fire pit: build your perfect outdoor gathering spot
A fire pit transforms a backyard into a cosy space, perfect for gatherings or relaxing evenings under the stars. Creating your own DIY fire pit adds charm to your outdoor space and saves money compared to buying pre-made designs. This guide walks you through everything—from planning to construction—while offering budget-friendly tips to keep the project manageable.
Planning your DIY fire pit
Check local fire codes.
Before starting, it is essential to confirm whether fire pits are allowed in your area. Some locations restrict outdoor fires or require fire pits to be placed far from buildings, fences, or trees. This step ensures your project is legal and safe.
Select the perfect location.
Choose a flat, open space far from structures, trees, or flammable materials. Consider wind direction to prevent smoke from blowing into living areas. A well-planned spot will enhance safety and comfort for you and your guests.
Materials and tools required
Building a fire pit doesn’t demand sophisticated tools or expensive materials. Here’s a list of essentials to get started:
- Bricks or retaining wall blocks: Choose heat-resistant options like fire bricks or concrete pavers.
- Gravel: Acts as a drainage layer to prevent water from pooling inside the pit.
- String, tape measure, and stake: For marking the layout of your fire pit.
- Shovel and trowel: To dig the pit and smooth out the base.
- Tamp and level: Ensure the ground is flat for stable brick placement.
- Optional fire-resistant mortar: For added strength between the layers of bricks.
Step-by-step construction process
Mark the area
Begin by deciding the size of your fire pit, typically around 4-5 feet in diameter. Insert a stake into the ground at the pit’s centre and tie a string to it. Measure the desired radius with the string, and use it to trace a perfect circle on the ground by dragging the sharp end of a trowel along the perimeter.
Dig out the pit
Once the circle is marked, use a shovel to dig out the grass and soil within the circle. Aim for a depth of 6 to 12 inches, enough to contain the fire while maintaining safety. If necessary, call utility services before digging to avoid hitting underground lines.
Level the surface
After digging, tamp down the soil to create a compact surface. Use a level to ensure the area is flat—this is crucial to keep the bricks stable. Adjust the ground as needed until the surface is smooth.
Add a gravel layer
Spread a thick layer of gravel at the bottom of the pit, at least 2 inches deep. Gravel helps with drainage, preventing water from collecting inside. Use a rake or your trowel to distribute the gravel evenly.
Build the fire pit walls
Now it’s time to stack the bricks. Start by placing the first layer of bricks or pavers along the circle’s edge. Stagger each new layer by placing bricks halfway over the ones below for stability. This pattern will lock them in place. If desired, use fire-resistant mortar to reinforce the structure. Adding a layer of fire bricks on the inner side enhances safety by withstanding higher temperatures.
Final touches
Arrange comfortable seating around the fire pit. Adirondack chairs or outdoor benches make great options. Set up a small wood storage area nearby to keep firewood within reach. With everything in place, your fire pit is ready for use.
Design ideas and budget tips
Explore creative styles
A DIY fire pit allows you to experiment with styles. Try an in-ground design for a minimalist look, or opt for modern metal fire pits using recycled containers. Incorporate decorative stones or bricks for a rustic vibe. You can also build a tabletop fire pit for small spaces.
Save on materials
Building a fire pit on a budget is possible using salvaged or second-hand materials. Old bricks, metal planters, or drum barrels can be repurposed creatively. Many DIY fire pits can be built for less than £80 by sourcing affordable materials and skipping unnecessary decorative elements.
Safety tips for using your fire pit
- Keep a fire extinguisher or bucket of water nearby during use.
- Avoid using lighter fluid or gasoline to start the fire.
- Regularly clean ash buildup to maintain good airflow.
- Always supervise children and pets around the fire pit.
FAQs
What is the best thing to put under a fire pit?
Using sand at the bottom of a fire pit is highly recommended, as it absorbs heat efficiently and protects the base from intense flames.
How do you make a bonfire at home?
Arrange stones or bricks in a circle. Use tinder to create a teepee shape and place logs nearby. Light the fuel and let it ignite the logs.
Can I just dig a hole for a fire pit?
Yes, but ensure it’s located far from trees, structures, or anything flammable.
What is a good bottom for a fire pit?
A combination of sand and gravel provides stability and promotes even heat distribution.
Can I use regular bricks for a fire pit?
Regular bricks can work, but they may crack over time. Fire bricks are a better option for heat resistance.
