Outdoor Fireplace Cinder Block Plans

Essential Aspects of Outdoor Fireplace Cinder Block Plans

Building an outdoor fireplace using cinder blocks requires careful planning and execution. Here are some essential aspects to consider when creating cinder block fireplace plans:

1. Fire Pit Design

Determine the shape and size of your fire pit. Consider the available space, seating capacity, and desired ambiance. Common shapes include square, rectangular, or circular. The size should accommodate firewood and provide ample seating around it.

2. Cinder Block Selection

Choose high-quality cinder blocks that are resistant to heat and moisture. Use standard 8-inch or 12-inch blocks for the foundation and walls. Consider using decorative blocks for the facing to enhance aesthetics.

3. Foundation

Excavate an area for the foundation slightly larger than the fireplace's perimeter. Lay a layer of gravel and compact it to ensure a solid base. Pour a concrete footing that extends beyond the edges of the cinder blocks to provide support.

4. Wall Construction

Start by laying cinder blocks on the concrete footing. Use mortar to bond the blocks together, staggering the joints for added stability. Build the walls to the desired height, typically 3-4 feet. Ensure the walls are level and plumb using a level and plumb bob.

5. Chimney

Install a chimney to allow smoke to escape. Build a flue using cinder blocks or refractory bricks, extending it above the highest point of the roof. Secure the chimney with mortar and a chimney cap.

6. Firebox

Create a firebox inside the fireplace. Line the bottom with fire bricks or fire-resistant cement. Use a metal fire grate to elevate the firewood and allow air circulation.

7. Mantel and Surround

Add a mantel or surround to enhance the fireplace's aesthetic appeal. Use stone, brick, or wood for the mantel, and consider decorative elements such as corbels or fluted columns for the surround.

8. Safety Measures

Incorporate safety features such as a spark arrester on the chimney to prevent embers from escaping. Keep a fire extinguisher nearby and maintain a clear area around the fireplace for safety.
