How to Build an Outdoor Fireplace Out of Landscape Pavers

An outdoor fireplace can be a stunning addition to any backyard, providing warmth, ambiance, and a focal point for gatherings. Building one from landscape pavers is a DIY project that can be achieved with some time, effort, and the right materials. The process involves planning, preparing the area, laying the foundation, constructing the firebox, and finishing the fireplace. This guide will detail the steps involved in building an outdoor fireplace using landscape pavers.

Planning Your Outdoor Fireplace

Before starting construction, carefully plan the design and size of your fireplace to ensure it fits your needs and the available space. Consider the following factors:

Location: Choose a level and accessible spot that is away from flammable materials and with sufficient clearance from any structures. Take into account prevailing winds and ensure that smoke will not be directed towards surrounding structures or neighboring properties.
Size: The size of your fireplace will depend on the space available and the number of people you expect to gather around it. A smaller fireplace is suitable for intimate gatherings, while a larger one can accommodate more people.
Design: Choose a design that complements your existing landscaping and the overall style of your home. Consider the shape, height, and overall aesthetic of the fireplace.
Materials: Landscape pavers come in various materials, colors, and sizes. Choose options that are durable, fire-resistant, and complement your design aesthetic. Ensure the pavers are frost-proof if you reside in an area with freezing temperatures.
Firebox: The firebox is the central component of your fireplace and will require a heat-resistant material, such as firebricks or steel. Consider the size of the firebox based on the size of the fireplace and the intended use.

Preparing the Area and Foundation

Once you have planned your fireplace, prepare the area and construct the foundation. Follow these steps:

Clear the area: Remove any vegetation, debris, and existing landscaping from the designated location. Level the ground using a rake and level, making sure there is a slight slope away from the fireplace to prevent water accumulation.
Excavate the foundation: Dig a rectangular hole for the foundation, ensuring it's slightly larger than the base of your fireplace to allow for a layer of gravel. The depth should be at least 8-10 inches to provide a solid base.
Lay the gravel: Fill the excavation with 4-6 inches of gravel to provide drainage and a stable base. Tamp the gravel down firmly to create a solid and even layer.
Construct the foundation: Use concrete blocks or a concrete slab to create the foundation. Ensure the foundation is level and plumb using a level and plumb bob. If using concrete blocks, secure them together with mortar. If you are using a concrete slab, allow it to cure completely before proceeding.

Building the Firebox and Fireplace Structure

After the foundation has cured, you can build the firebox and the rest of the fireplace structure using landscape pavers. Here's how:

Construct the firebox: Determine the shape, size, and location of the firebox. Lay firebricks or steel panels on the foundation to form the base and sides of the firebox. Ensure a gap between the firebox and the pavers to allow for air circulation. If you are using firebricks, use fire mortar to secure them together.
Install the pavers: Begin by laying the pavers around the firebox to create the base of the fireplace. Use a mortar bed or a layer of sand to ensure the pavers are level and secure. Continue laying the pavers upwards to create the desired height and shape of the fireplace.
Create openings: Leave openings for the firebox opening and any desired vents or air intakes. If you want to install a fireplace screen or mantel, incorporate the necessary supports during construction.
Secure the pavers: Use mortar to secure the pavers together, ensuring a strong and stable structure. Allow the mortar to cure fully before proceeding to the next stage.

Finishing Touches

Once the fireplace structure is complete, add finishing touches to enhance its aesthetics and functionality. Consider the following:

Grouting: Use a heat-resistant grout to fill the gaps between the pavers, preventing dirt and moisture from entering and enhancing the overall appearance.
Sealing: Apply a sealant to protect the pavers from water damage, stains, and weathering. Choose a sealant specifically designed for outdoor pavers and follow the manufacturer's instructions carefully.
Decorative elements: Add decorative elements to personalize your fireplace. Consider adding a mantel, decorative stones, or landscaping around the base.
Heat shield: Install a heat shield around the fireplace to prevent the surrounding area from overheating.

By following these steps, you can create a beautiful and functional outdoor fireplace using landscape pavers. However, it is essential to consult with local building codes and regulations before starting any construction. Always prioritize safety when working with fire and ensure proper ventilation for a safe and enjoyable outdoor fireplace experience.
