How to Build a Corner Fireplace

A corner fireplace can be a stunning focal point in any living room, adding warmth, ambiance, and a touch of elegance. While building a fireplace is a complex project, it can be tackled with careful planning and execution. This guide provides a step-by-step approach to building your own corner fireplace, covering the essential considerations for a successful outcome.

1. Planning and Design

The first step in building a corner fireplace is to carefully plan and design the project. This includes determining the style, size, and materials for the fireplace. Consider the existing architectural style of your home and the overall aesthetics you want to achieve.

Here are some key aspects to consider during the planning phase:

Fireplace type: Choose between a traditional wood-burning fireplace, a gas fireplace, or an electric fireplace. Each option has its advantages and disadvantages in terms of efficiency, maintenance, and cost.
Size and dimensions: Determine the desired size and dimensions of the fireplace, considering the available space in the corner and the overall size of the room.
Fireplace surround: Choose the materials for the fireplace surround, such as stone, brick, tile, or wood. The chosen materials should complement the architectural style and provide a durable and aesthetically pleasing finish.
Fireplace mantel: Consider the design and materials for the mantel, which can add a decorative touch and provide a shelf for displaying items.
Firebox and hearth: Choose the materials for the firebox and hearth, ensuring they are heat-resistant and can withstand the high temperatures associated with fire.
Ventilation and chimney: If building a wood-burning fireplace, ensure adequate ventilation and a properly sized chimney for safe and efficient operation.

2. Preparing the Foundation

Once the design is finalized, the next step is to prepare the foundation for the fireplace. This involves creating a solid and level base to support the weight of the fireplace and withstand the heat generated.

Follow these steps to prepare the foundation:

Clear the area: Remove any existing flooring or obstacles in the corner where the fireplace will be built.
Construct a base: Build a solid base using concrete, brick, or a combination of both. Ensure the base is level and properly supported by the subfloor.
Install a vapor barrier: Apply a vapor barrier to prevent moisture from migrating from the ground into the fireplace structure.
Create the hearth: Build the hearth using fire-resistant materials such as brick, tile, or stone. Ensure the hearth extends at least 16 inches in front of the fireplace opening.

3. Building the Fireplace Structure

With the foundation prepared, you can begin building the fireplace structure. This involves constructing the firebox, chimney, and surround.

Here are the steps involved in building the fireplace structure:

Install the firebox: Position and install the firebox, ensuring it is securely anchored to the foundation.
Construct the chimney: Build the chimney using fire-resistant materials such as brick or concrete block. The chimney should be properly vented and extend above the roofline.
Build the surround: Construct the fireplace surround using the chosen materials, ensuring it is properly sealed and insulated to prevent heat loss.
Install the mantel: Install the fireplace mantel, ensuring it is securely attached to the surround and can withstand the weight of decorative items.

4. Finishing Touches

Once the fireplace structure is complete, you can add the finishing touches. This includes installing a fire grate, a damper, and a spark screen.

Follow these steps to add the finishing touches:

Install a fire grate: Install a fire grate to support the burning wood or gas logs.
Install a damper: Install a damper to control the airflow within the chimney and prevent drafts when the fireplace is not in use.
Install a spark screen: Install a spark screen to prevent sparks from escaping the fireplace and igniting surrounding materials.
