How to Build an Outdoor Fireplace: Warm Up Your Outdoors

An indoor outdoor fireplace wood burning setup can add a cozy and inviting touch to any backyard. Whether you’re looking to entertain guests, cook outdoors, or simply enjoy a peaceful evening by the fire, an outdoor fireplace is a perfect solution.

In this guide, I will walk you through all the steps to how to build an outdoor fireplace and build a beautiful and functional outside fire place, covering everything from outdoor fireplace measurements to outdoor fireplace grill designs.

Planning Your Outdoor Fireplace

Before you begin any building project, it’s crucial to plan thoroughly. Decide the primary purpose of your outdoor wood burning fireplace with chimney.

Do you want it for warmth, ambiance, cooking, or all of the above?

A fireplace designed primarily for cooking might include specific outdoor fireplace grill designs, while a decorative fireplace may prioritize aesthetics over function.

Choosing the Right Location

Your fireplace’s location will depend on several factors, including safety, ease of use, and how it complements your landscape.

The spot should be away from trees and wooden structures. Additionally, you’ll need to take your outdoor fireplace measurements into account, ensuring it fits the space available while still leaving room for seating and any other backyard features you want.

Be sure to check local building codes and regulations, as many areas have restrictions on outdoor fire features like a natural stone outdoor fireplace. You’ll also want to know the masonry fireplace dimensions required for safety and functionality.

Design Considerations

Your outdoor fireplace design is an opportunity to reflect your personal style. There are various types of fireplaces, including those built with brick, stone, or concrete.

A natural stone outdoor fireplace adds rustic charm, while brick and concrete provide a modern or traditional look.

Wood-burning vs. Gas Fireplaces

One of the most important decisions you’ll make is whether you want a traditional indoor outdoor fireplace wood burning or a gas fireplace. Wood-burning fireplaces have a classic feel, and their crackling logs and smoky aroma create an ambiance that’s hard to replicate.

On the other hand, gas fireplaces are more convenient to operate and maintain. You could even look into indoor fireplace kits if you want a pre-fabricated option for indoor or outdoor use.

Gathering the Necessary Materials and Tools

Whether you’re going for a diy outdoor fireplace project or hiring a professional, you’ll need to gather the right materials and tools before beginning.

Essential Tools

• Shovels for digging the foundation
• Levels to ensure accuracy
• Trowels for applying mortar
• A brick or stone saw
• Hammer and chisel for cutting stone

Materials

• Concrete for the foundation
• Firebrick for the firebox
• Cement blocks or bricks for the structure
• Rebar for reinforcement
• Mortar mix for binding materials
• Stone or brick veneer for the finishing touches

Building a Solid Foundation

A solid foundation is critical for any outside fire place. Here’s a step-by-step guide to laying the foundation:

1. Mark the Area: Use stakes and string to define the fireplace’s location, keeping in mind the outdoor fireplace measurements you’ve planned.
2. Dig the Foundation: Excavate a hole about 12 inches deep. Ensure it’s level.
3. Add Gravel and Rebar: Lay down gravel for drainage and insert rebar for reinforcement.
4. Pour Concrete: Fill the foundation hole with concrete and smooth it out. Let it cure for 48 hours before moving on to the next step.

Building the Fireplace Base

Once the foundation is set, it’s time to build the base, which will support the firebox and chimney.

1. Lay the Blocks: Stack cement blocks or bricks to create the base. Use a level to make sure everything is even. The base must be strong enough to support the firebox and chimney, so check your masonry fireplace dimensions.
2. Reinforce the Base: For extra durability, use rebar and mortar to bind the bricks together.

Constructing the Firebox

The firebox is where the fire will burn, so it needs to be durable and heat-resistant.

1. Build the Firebox Frame: Use a firebrick to create the walls of the firebox. If you’re unsure how to get started, learning how to build a fireplace frame will provide you with the guidance you need. The opening should be large enough to accommodate the size of the fire you plan to build.
2. Apply Heat-resistant Mortar: Firebrick requires a special type of mortar that can withstand high temperatures.
3. Add Ventilation: Make sure the top of the firebox slopes inward to help smoke flow smoothly into the chimney.

Building the Chimney

A properly constructed chimney ensures that smoke escapes without backdrafting into your outdoor space. Whether you’re building a diy outdoor fireplace or a custom structure, follow these steps:

1. Build the Chimney Stack: Continue stacking bricks or stones above the firebox to form the chimney. Ensure the height meets local codes.
2. Insert a Flue Liner: A flue liner helps improve the fireplace’s efficiency and directs smoke upward. It’s a crucial part of any outdoor wood burning fireplace with chimney.
3. Install a Spark Arrestor: This device will prevent embers from escaping the chimney.

Finishing Touches for the Fireplace Structure

Once the main structure is complete, it’s time to finish it off with aesthetic details.

1. Apply a Stone or Brick Veneer: Use a veneer made of brick, stone, or concrete to give the fireplace a polished, cohesive look.
2. Install a Mantel: If desired, add a decorative mantel to enhance the fireplace’s appearance.
3. Seal the Structure: Protect your fireplace from weather by applying a heat-resistant sealant to the stone or brick.

Creating a Hearth

The hearth adds both functionality and style. It offers a space to rest tools or logs and serves as a natural focal point for the design.

1. Lay the Hearth: Install a stone or brick hearth directly in front of the firebox.
2. Ensure Durability: The hearth must be made of non-flammable, durable materials that match the rest of your fireplace’s design.

Safety Considerations

Safety is paramount when constructing a diy outdoor fireplace. Here are a few tips:

• Install a Spark Screen: This will prevent embers from flying out of the firebox.
• Add a Spark Arrestor in the Chimney: Protect against embers escaping into the air.
• Maintain Safe Distances: Ensure your fireplace is far from any flammable structures, such as a wooden deck or outdoor furniture.

Outdoor Fireplace Maintenance

Maintaining your fireplace ensures its longevity and safety.

• Clean the Firebox Regularly: Remove ashes after every use.
• Inspect the Chimney: Check the chimney annually for blockages or cracks.
• Seasonal Maintenance: Cover the fireplace during off-seasons to protect it from the elements.

Landscaping Around the Fireplace

Once your fireplace is complete, you can focus on making the surrounding area inviting. Add outdoor seating, potted plants, and lighting to create a cozy and relaxing space around your outdoor wall fireplace.

Cost Estimation and Budgeting

The cost of building an outdoor fireplace can vary widely, especially when incorporating features like an outdoor wall fireplace or specific outdoor fireplace grill designs. Generally, natural stone outdoor fireplaces and custom work can be on the higher end of the budget.

Factors affecting cost include:

• Materials: Stone is generally more expensive than brick.
• Labor: DIY projects can save on labor costs, but they require time and skill.
• Size: Larger fireplaces with intricate designs or built-in features will cost more.

Conclusion

Building an outdoor fireplace, whether it’s a small outdoor wall fireplace or a large, custom-designed natural stone outdoor fireplace, is an excellent way to enhance your outdoor living space.

By following this guide, from planning and choosing the right outdoor fireplace measurements to learning how to build a fireplace frame, you’ll be able to create a durable and beautiful outdoor feature. Whether it’s for cozy evenings, entertaining guests, or outdoor cooking, a fireplace adds warmth and character to any backyard.
