How to Build a Small Brick Outdoor Fireplace

An outdoor fireplace can add warmth, ambiance, and functionality to any backyard space. It’s a great place to gather with family and friends, roast marshmallows, and enjoy the beauty of nature. While building a large fireplace can be a major undertaking, creating a smaller version is a manageable project for many DIY enthusiasts. This article will guide you through the process of building a small brick outdoor fireplace, providing clear steps and tips for a successful outcome.

Step 1: Planning and Design

Before starting construction, it’s crucial to plan and design your fireplace carefully. This phase involves several key considerations:

Location: Choose a suitable location for your fireplace, taking into account factors like wind exposure, proximity to trees or structures, and the overall layout of your yard. Ensure it’s far enough from flammable materials and meets local building codes.

Size and Shape: Determine the size and shape of your fireplace based on your needs and the available space. Consider the number of people you plan to accommodate, the type of firewood you’ll use, and the aesthetic you desire.

Materials: Select durable and weather-resistant materials for both the fireplace itself and the surrounding area. Bricks are a popular choice for their durability and classic look, while concrete blocks offer affordability.

Step 2: Foundation Construction

A solid foundation is essential for the stability and longevity of your fireplace. The following steps outline the foundation construction process:

Excavation and Leveling: Dig a hole slightly larger than the base of your fireplace. Ensure the bottom is level to provide a stable foundation.

Base Material: Fill the excavated area with a 4-6 inch layer of gravel for drainage. Follow this with a layer of concrete mix, ensuring it’s level and compact.

Allow Curing: Allow the concrete to cure for at least 24 hours before proceeding to the next step.

Step 3: Building the Fireplace Walls

Once the foundation is set, you can begin constructing the fireplace walls. Follow these steps:

Laying Bricks: Use mortar to lay bricks in a chosen pattern, keeping them level and plumb. Use a level and plumb bob to ensure accuracy.

Building the Firebox: Construct the firebox using firebricks, as regular bricks can crack under high temperatures. The firebox should be slightly smaller than the overall fireplace opening, leaving room for mortar.

Adding a Lintel: Install a lintel to support the weight of the bricks above the fireplace opening. This is essential for preventing cracks and ensuring structural integrity.

Step 4: Chimney Construction

For safety and efficiency, a chimney is crucial for channeling smoke and gases upwards. It’s important to consult local building codes and regulations regarding chimney construction standards.

Chimney Height: Building codes often require a minimum chimney height for effective venting. The chimney should extend at least 10 feet above the roofline to ensure proper draft.

Chimney Material: Choose a fire-resistant material for the chimney, often metal or brick. Ensure it’s properly sealed to prevent leaks and drafts.

Chimney Cap: Install a chimney cap to prevent rain and debris from entering the chimney.

Step 5: Finishing Touches

After completing the main construction, add the finishing touches to your fireplace:

Mortar Joints: Smooth and clean the mortar joints for a finished look. Use a tool to create a consistent groove or pattern in the mortar.

Fireplace Surround: Build a decorative surround around the fireplace opening using bricks, stone, or other materials. Consider adding a hearth for a place to set items or stand safely.

Landscape Design: Integrate your fireplace into the surrounding landscape by adding plants, rocks, or other elements for a cohesive look.
