There are many benefits to building an outdoor fireplace, both practical and aesthetic. Here are just a few reasons why you should consider adding one to your backyard:

An outdoor fireplace can provide warmth during cool evenings or chilly seasons, allowing you to use your outdoor space for longer. This means you can enjoy the fresh air and nature without being limited by the weather.

Gather Around the Fire:

A fireplace creates a natural focal point for gatherings, making it a perfect spot for friends and family to gather and socialize. It also provides a cozy atmosphere for intimate conversations or quiet moments alone.

Increase Property Value:

Adding an outdoor fireplace can increase your property’s value, making it a worthwhile investment if you ever decide to sell your home. In fact, according to the National Association of Realtors, fire features are one of the most desirable outdoor features among homebuyers.

7 Simple Step-by-step Guidelines on How to Build an Outdoor Fireplace Cheap

Step 1: Choose the Location 

The first step in building an affordable outdoor fireplace is selecting the right location. Look for a spot in your yard that offers ample space, a flat surface, and complies with local guidelines or fire codes. Ideally, the location should provide a safe distance from any structures, trees, or flammable materials, ensuring the fireplace does not pose a safety risk.

Consider the prevailing wind direction to avoid smoke blowing toward seating areas or your home. Additionally, situate the fireplace in a spot that enhances the aesthetics of your outdoor space while maintaining accessibility for gatherings and maintenance needs. Proper planning at this stage will lay a solid foundation for a successful project.

Step 2: Determine the Size and Shape 

Once you’ve chosen the location, the next step is to decide on the size and shape of your outdoor fireplace. Consider how the fireplace will fit into your outdoor space and its intended purpose. A smaller, more compact design may be suitable for intimate spaces, while a larger fireplace can serve as a striking focal point for bigger yards or frequent gatherings. 

For a budget-friendly approach, sketch a simple design that minimizes material usage while maintaining functionality. Rectangular or square shapes are generally easier and cheaper to construct than intricate designs. Additionally, think about the height of the structure to ensure it provides adequate warmth and aesthetic appeal without obstructing views or creating smoke-related issues. Solidifying these details will streamline the construction process and help avoid unnecessary expenses.

Step 3: Gather Materials

When it comes to building an affordable outdoor fireplace, selecting the right materials can make all the difference. Traditional brick or stone may be too expensive, but there are alternative options that can achieve a similar look at a lower cost. Consider using pavers, cinder blocks, or even natural materials like adobe or river rocks for a rustic feel.

You will also need tools such as a level, shovel, trowel, and masonry saw to build your fireplace. These items can often be rented from local hardware stores rather than purchased outright.

Step 4: Build the Foundation 

A solid foundation is key to ensuring your outdoor fireplace is stable and long-lasting. Start by marking the area where the fireplace will be constructed using stakes and string. Clear the space of grass, debris, or any loose soil, then dig a shallow trench about 6 to 8 inches deep, depending on the soil type and fireplace size. Ensure the trench is level to avoid structural issues later on.

Next, fill the trench with gravel or crushed stone to create a sturdy base that enhances drainage and prevents shifting over time. Compact the layer using a tamper to ensure it is solid and even. For added stability, pour a thin layer of concrete over the gravel if your budget allows. Smooth out the concrete using a trowel and check for levelness. Allow the foundation to cure for at least 24 to 48 hours before proceeding to the next steps. Taking the time to properly build the foundation will provide a strong base for the fireplace and help avoid costly repairs in the future.

Step 5: Lay the Bricks 

With the foundation complete, it’s time to start laying the bricks or other selected materials for the structure of your outdoor fireplace. Begin by applying a layer of mortar along the foundation where the first row of bricks will be placed. Use a trowel to spread the mortar evenly, ensuring a solid bond between the foundation and the bricks. 

Carefully place the first row of bricks in a straight line, checking each brick with a level to ensure they are even and aligned. Leave a small gap between each brick for mortar and use a pointing trowel to fill the gaps neatly. Continue adding mortar and laying bricks row by row, staggering them in a bricklaying pattern for added stability and a professional look. 

If you’re incorporating firebricks to better withstand heat, line the inside of the fireplace with them after constructing the outer structure. Be sure to regularly check your progress with a level and adjust as needed to maintain an even and sturdy build. Smooth out excess mortar as you go to keep the structure clean and polished. Building your fireplace slowly and methodically at this stage will ensure a durable and attractive final result.

Step 6: Add Fireproof Materials 

To ensure your outdoor fireplace is safe and functional, it’s crucial to incorporate fireproof materials in its construction. Begin by lining the interior of the fireplace with firebricks, as these are specifically designed to withstand high temperatures without cracking or degrading. Heat-resistant mortar is used to adhere the firebricks to the inner walls, creating a durable barrier that protects the outer structure from intense heat. 

For additional safety, consider adding fireproof panels or a metal firebox insert. These elements can further enhance the fireplace’s durability and improve heat retention, ensuring more efficient performance. Make sure to carefully follow the manufacturer’s guidelines when installing these materials. 

By taking the time to properly add fireproof materials, you’re not only improving the lifespan of your fireplace but also ensuring it operates safely during use. This step is essential for creating a fireplace that can be enjoyed for years to come.

Step 7: Finishing Touches 

Once the structure of your outdoor fireplace is complete, it’s time to add some final touches. Use a stiff brush and warm water to remove any excess mortar or debris from the surface of the bricks. For added aesthetics, consider adding a decorative stone veneer or stucco finish to the exterior of the fireplace. These materials are budget-friendly and can give your fireplace a custom, high-end look.

You may also want to incorporate a chimney for proper ventilation and to prevent smoke from billowing out into your outdoor living space. This can be built using the same materials as the fireplace or with a metal chimney kit for added convenience.

Following these steps on how to build an outdoor fireplace cheap will help you build an affordable and functional outdoor fireplace that can enhance your outdoor living space. Remember to always double-check your work, use proper safety measures, and consult with a professional if needed to ensure the best results. So gather your materials, start building, and get ready to cozy up by the fire in your own backyard oasis.

Additional Tips for Maintenance

To keep your outdoor fireplace in top condition, it’s important to perform regular maintenance. This includes cleaning out any debris such as ashes or soot, after each use, checking for cracks or loose bricks periodically, and ensuring the chimney is clean and free of any obstructions.

It’s also essential to protect your fireplace from harsh weather conditions. Consider covering it with a tarp or investing in a waterproof cover during periods of heavy rain or snow. This will prevent water damage and prolong the lifespan of your fireplace.

Additionally, be sure to use proper firewood for your outdoor fireplace. Avoid using wet or green wood, as this can cause excessive smoke and create buildup on the interior walls of the fireplace. Stick with seasoned hardwoods such as oak, maple, or hickory for optimal burning and less maintenance.

By following these tips and properly maintaining your outdoor fireplace, you can enjoy cozy fires for years to come without breaking the bank. Happy building!
