Imagine transforming your backyard into a cozy, inviting space where you can relax, entertain, and create lasting memories. A below ground fire pit area is not just a feature, it's an experience that brings warmth, light, and a touch of rustic charm to your outdoor living space. Let's delve into the world of subterranean fire pits and explore how you can create a stunning, safe, and functional below ground fire pit area.

Before we dive into the details, let's address the elephant in the room. Yes, building a below ground fire pit involves some work, but the result is a unique, eye-catching feature that elevates your outdoor space. Plus, it's a project you can tackle over a weekend with the right planning and a bit of elbow grease. So, are you ready to roll up your sleeves and create a below ground fire pit area that's the talk of the town? Let's get started!

Designing Your Below Ground Fire Pit Area

Designing your below ground fire pit area is an exciting process that allows you to express your creativity and personal style. The first step is to decide on the size and shape of your fire pit. Circular fire pits are classic and versatile, while square or rectangular pits can create a modern, sleek look. Consider the size of your backyard and the number of people you want to accommodate when making this decision.

Watch - Create a Sunken Fire Pit That Feels Like a Natural Outdoor Room A sunken fire pit instantly changes the feel of a landscape. Instead of placing a fire feature on top of the yard, this design nestles it into the ground, creating a cozy gathering space that feels protected, intentional, and connected to the surrounding plants and trees. With natural stone, gravel underfoot, and simple seating, it becomes a place people naturally gravitate toward. What Makes This Design Work Lowering the seating area slightly below grade creates a sense of enclosure without blocking views. The curved stone wall defines the space, provides informal seating, and helps retain warmth from the fire. Because everything sits low, the area blends into the landscape rather than dominating it. Using natural stone and native-style plantings keeps the space relaxed and timeless instead of formal or overbuilt. How to Build the Sunken Area Start by choosing a level spot with good drainage. Excavate a shallow circular or oval area deep enough for a gravel base and the fire pit itself. Compact the soil well and add a thick layer of gravel to create a stable, well-draining surface. Build the retaining wall using stacked natural stone, keeping the height low enough to feel open while still defining the space. Dry-stacking works well when stones are properly fitted and backed with compacted soil and gravel. Place the fire pit in the center, built from stone or a fire-rated insert, and fill the interior with gravel for safety and drainage. Seating and Layout Tips Arrange Adirondack-style chairs in a loose circle around the fire, leaving enough space to move comfortably. Keeping the chairs uniform in style and finish helps the space feel cohesive without being rigid. Leave a clear entry point into the pit area, often with a few stone steps or a gravel path leading in. Landscaping for a Natural Look Surround the fire pit with layered plantings rather than straight borders. Native grasses, flowering perennials, ferns, and low shrubs soften the stone and make the space feel established. Vary textures and heights so the area looks good even when flowers aren’t in bloom. Mulch and natural groundcover help the space transition smoothly into the surrounding landscape. Why This Is Worth the Effort A sunken fire pit creates a destination rather than just a feature. It feels sheltered without being closed in, works beautifully in both daylight and evening, and blends into the land instead of sitting on top of it. Done well, it becomes a year-round gathering place that looks like it’s always belonged exactly where it is. | Facebook

Next, think about the materials you want to use. Concrete blocks, bricks, and natural stone are popular choices for their durability and aesthetic appeal. You can also use a combination of materials to create a unique, custom look. Don't forget to factor in the cost of materials and any necessary tools when creating your budget.

Choosing the Right Location

Selecting the right location for your below ground fire pit is crucial for safety and functionality. Ideally, you want to place your fire pit at least 25 feet away from any structures, including your home, fences, and trees. This distance helps prevent the spread of sparks and ensures that smoke doesn't blow into your house or your neighbors'.

Additionally, consider the wind direction in your area and position your fire pit accordingly. You don't want smoke blowing into your seating area or your neighbor's yard. Finally, ensure that your fire pit is easily accessible from your patio or deck, making it a convenient gathering spot.

Preparing the Site

Once you've chosen the perfect location, it's time to prepare the site for construction. Start by marking out the dimensions of your fire pit using stakes and strings. Then, use a shovel to dig out the area to a depth of about 12 inches. This depth will provide enough space for the fire pit's structure and allow for proper drainage.

Next, create a base for your fire pit using gravel or crushed stone. This layer helps promote drainage and prevents water from accumulating in your fire pit. Spread a 2-3 inch layer of gravel evenly across the bottom of the pit, and use a rake to level it out. Now, you're ready to start building the walls of your fire pit.

Building the Fire Pit Structure

Building the walls of your below ground fire pit is a straightforward process that involves stacking bricks, concrete blocks, or stones to create a retaining wall. Start by laying the first course of blocks along the outer edge of the pit, using a level to ensure they're even and straight. Apply mortar between each block to create a strong, stable structure.

Continue stacking blocks, offsetting the vertical joints to create a sturdy, interlocking pattern. As you build upwards, periodically check the walls for plumb and level to ensure they're straight and even. Once you've reached your desired height, allow the mortar to cure according to the manufacturer's instructions before moving on to the next step.

Installing the Fire Pit Insert

Installing a fire pit insert is an optional but recommended step that adds safety and convenience to your below ground fire pit. Fire pit inserts are typically made of steel or cast iron and are designed to contain the fire within the pit, preventing sparks from flying out and reducing the risk of accidental burns.

To install the insert, measure the interior dimensions of your fire pit and choose an insert that fits snugly within the walls. Place the insert in the center of the pit, ensuring it's level and stable. If necessary, use a small amount of mortar to secure the insert in place. Once the insert is installed, you're ready to add the finishing touches to your below ground fire pit area.

Adding Safety Features and Accessories

Safety should always be a top priority when designing and using a below ground fire pit. Start by installing a grate or screen over the fire pit insert to prevent embers and sparks from escaping. You can also add a spark guard or screen that attaches to the top of the fire pit walls, providing an extra layer of protection.

Additionally, consider adding a windscreen to your fire pit to help protect against gusts of wind that can blow embers and smoke into your seating area. You can also install a rain cover to protect your fire pit from the elements when it's not in use. Finally, keep a fire extinguisher or a bucket of sand nearby to quickly extinguish any accidental fires.

Creating a Comfortable Seating Area

With the fire pit itself complete, it's time to focus on creating a comfortable, inviting seating area where you can relax and enjoy the warmth of the fire. Start by laying a patio stone or gravel path leading from your patio or deck to the fire pit. This path not only adds a touch of elegance but also helps prevent erosion and makes it easier to access the fire pit.

Next, choose comfortable, durable seating options that can withstand the elements. Teak, cedar, and other weather-resistant woods are excellent choices for outdoor furniture. You can also opt for metal or synthetic materials that require minimal maintenance. Don't forget to include plenty of cushions and pillows to make your seating area cozy and inviting.

Adding Ambient Lighting

Ambient lighting is essential for creating a warm, welcoming atmosphere in your below ground fire pit area. Start by installing solar or low-voltage landscape lights along the path leading to the fire pit. These lights not only provide guidance but also add a touch of elegance to your outdoor space.

Next, consider adding string lights, lanterns, or solar-powered stake lights around the perimeter of the seating area. These lights create a soft, inviting glow that makes your space feel cozy and inviting. You can also install a fire pit cover with built-in LED lights, providing both safety and ambiance.

Finishing Touches

Adding the final touches to your below ground fire pit area is the perfect opportunity to express your personal style and create a space that reflects your unique taste. Consider incorporating plants, flowers, or greenery around the fire pit to add a touch of nature to your outdoor space. You can also add decorative elements like garden statues, wind chimes, or outdoor art to create a cohesive, inviting atmosphere.

Don't forget to include plenty of blankets and throws in a nearby storage chest or basket, allowing you and your guests to stay warm and cozy on chilly evenings. Finally, consider adding a outdoor speaker or sound system to set the mood with your favorite music as you gather around the fire.

As you sit back and enjoy the warmth of your below ground fire pit, surrounded by the people you love, you'll appreciate the time and effort you invested in creating this magical space. Your below ground fire pit area is more than just a feature – it's a gathering place, a sanctuary, and a testament to your creativity and craftsmanship. So go ahead, light the fire, and let the memories begin.
