Step-by-step Guide to Building an Outdoor Fireplace

Do you dream of cozy evenings spent gathered around a crackling fire in your backyard? Building an outdoor fireplace can turn that dream into reality. Not only will it provide a warm and inviting atmosphere, but it can also serve as a focal point for your outdoor living space. If you’re ready to embark on this exciting project, here is a step-by-step guide to help you get started.

Planning and Design

Before you begin building your outdoor fireplace, it’s important to plan and design the layout. Consider the size and location of your fireplace, as well as how it will fit into your overall outdoor space. Take into account any local building codes or regulations that may apply.

Materials and Tools

The first step in building your outdoor fireplace is gathering the necessary materials and tools. You will need fire-resistant bricks or stones, concrete blocks, mortar, a firebox kit, a chimney flue, a metal grate, and a fireproof cap. Additionally, you will need a shovel, a level, a trowel, a masonry brush, and a rubber mallet.

Foundation and Base

Start by laying a solid foundation for your outdoor fireplace. Dig a trench and fill it with gravel to create a stable base. Use a level to ensure that the gravel is even and compacted. Next, lay the first layer of concrete blocks or fire-resistant bricks, using mortar to secure them in place. Check for levelness as you go.

Building the Firebox

Once the base is complete, it’s time to build the firebox. This is where the fire will be contained. If you’re using a firebox kit, follow the manufacturer’s instructions for assembly. If not, stack the bricks or blocks to form the walls of the firebox, leaving space for the opening at the front. Use mortar to secure the bricks or blocks together.

Constructing the Chimney

With the firebox in place, it’s time to construct the chimney. Stack the bricks or blocks to form the back and sides of the chimney, leaving space for the flue. Use mortar to secure the bricks or blocks together. Install the chimney flue according to the manufacturer’s instructions.

Finishing Touches

Once the structure of your outdoor fireplace is complete, it’s time to add the finishing touches. Apply a layer of mortar to the exterior of the fireplace, using a masonry brush to create a textured finish. Allow the mortar to dry before applying a second coat, if desired. Install a metal grate inside the firebox to support the wood, and add a fireproof cap to the top of the chimney to protect it from the elements.

Enjoying Your Outdoor Fireplace

With your outdoor fireplace complete, it’s time to sit back, relax, and enjoy the warmth and ambiance it provides. Gather some firewood, light the fire, and let the flames dance as you create lasting memories with family and friends. Remember to practice proper fire safety and always extinguish the fire before leaving it unattended.


Building an outdoor fireplace can be a rewarding and enjoyable project. By following this step-by-step guide, you can create a beautiful and functional addition to your outdoor living space. From the initial planning and design to the final finishing touches, each step is crucial in creating a safe and inviting fireplace that you can enjoy for years to come. So, grab your tools and get ready to embark on this exciting DIY project.
