What you need to know before you start building your own fire pit

Location

To start, decide on the size, shape and location of the fire pit. The fire pit location will depend on the size of your outdoor space as well as local regulations. Some areas require fire pits to be placed at least 30 feet away from buildings. 

Consider whether it should be close to seating areas or further away from structures that could be damaged by smoke or sparks. It is also important to make sure there is adequate space around the outside of the fire pit for safety reasons, including providing enough room for people to move around it. 

Size and shape

When it comes to fire pit shapes, the most popular shapes are circle and square. 

Thinking about the size, choose an appropriate size for your firepit depending on how many people will use it at one time. The minimum diameter should be around 2 feet, but you can go over that depending on your needs and the space available. Generally speaking, 3 feet diameter is a good size to contain a fire and is suitable for cooking. The walls should be between 6 and 10 inches high in order to contain firewood, sparks and embers.

How to build a cheap backyard fire pit? Here is how:

Prepare the surface

Now it’s time to start building! Begin by creating a flat and stable area that is slightly larger than the desired size of your fire pit; this will give you some room to work with when constructing it. 

Measure and mark the outline of your fire pit. If you are going to use your firepit for grilling, measure the grill grate first and make sure that the fire pit matches it. 

Build the walls

Next, use the stones and cement to construct walls around the area that create an enclosed space for your flames. 

Line the bottom 

After that is finished, line the bottom of your DIY fire pit with gravel. This will help promote better drainage of rainwater. 

Finally, it’s time for testing! To make sure everything has been built correctly and safely light a small test flame inside. If all goes well then congratulations – you have now built yourself an affordable yet reliable new addition to your outdoor space! 

How long does it take to build a fire pit?

It’s actually quicker than you think! If you have all the tools and materials laid out and you’ve landscaped the area for your fire pit, it takes a just couple of hours to build the firepit walls. It will obviously depend on the size of the fire pit and your experience. 

So this is a simple way to build a fire pit for less than $100. 

However, there is more you can add to your fire pit, e.g. firebricks and lava racks. This video shows how to build a rectangular fire pit with stones, fire bricks and concrete adhesive instead of cement. The procedure is similar to what we’ve described.

Consider adding a grill grate to your fire pit

If you are planning on grilling over your fire pit, consider adding a BBQ grate; it’s best to plan on that before you start building your fire pit walls to make sure that they fit together. Also, plan on the level at which the grate will sit to ensure the right distance from the flames. Ideally, you should be able to use it at two or three different levels.

Think about heat retention

We’ve already mentioned heat-retaining bricks you can use for fire pit walls. But there is more you can do to prevent the heat from escaping into the air. Consider getting a heat shield that you can place above the flames, so the heat can be distributed to the sides giving warmth to everyone sitting around. There are also windscreens you can place around the fire pit area and prevent the wind from blowing the heat away.

How do I make a fire pit safe?

Here are some tips for making sure that your fire pit is as safe as possible: 

First, make sure that your fire pit is located at a sufficient distance from any buildings or trees. Keep it at least ten feet away from any buildings, decks, or other structures in order to prevent accidental fires. 

Second, it’s also important to make sure that no combustible materials such as gasoline and propane are stored or used near the fire pit. 

Third, ensure that the area around the fire pit is free of debris like leaves and twigs or plants growing nearby which could catch on fire quickly. 

Fourth, always have at hand a fire extinguisher, a fire blanket or a bucket of sand and spade in case of emergency. 

Additionally, if you plan on cooking over your firepit, make sure you have heat-resistant tools and utensils cutlery specifically made for high temperatures. 

Finally, consider investing in safety spark screens for your fire pit. Screens will help reduce flying sparks and keep children and pets away from an open flame while still allowing you to enjoy the warmth of flames. 

By following these simple steps you can rest assured knowing that your backyard firepit is safe for everyone!
