DIY Brick Barbecue: How to Build Your Own Outdoor Grill 2026

If you have a garden, you've probably thought about building a brick barbecue at some point. The first step is to prepare the foundation on which to build the structure. Let's create a solid, flat surface by digging about 20 centimeters deep and filling it with stones and gravel. Cover with soil and tamp it down very well.

Place some heavy, large concrete or stone tiles and fix them together with a bit of cement mortar. For all your home improvement needs, from tools to materials, we've got you covered.

Laying the First Course of Bricks

On this base, lay the first course of bricks in a U-shape with 2 elements on the short sides and 4 on the long side; the mortar should always be kept uniform in thickness. Prepare the cooking surface made of cast iron or sheet metal (2 mm thick) with a flap folded over the lower support. The grill rests on one of the upper supports of the brick barbecue.

How to Build a Brick Barbecue

To cook outdoors practically and safely, let's build a brick barbecue ourselves using facing bricks—more expensive, but more beautiful. After laying the first course of bricks, check with a spirit level. Continue laying the bricks and check both the flatness of the courses and the verticality of the wall.

The cooking grills rest on three bricks placed sideways in the sides, protruding both inside and outside. We need to touch up the mortar joints between the brick courses. After an adequate period of rest and drying of the cement, your DIY garden brick barbecue is ready to use.

Essential Tools and Accessories

• Spirit level and trowel for precise brickwork
• Cast iron or steel cooking grate
• Charcoal tray or gas burner insert
• Weatherproof cover for protection

Enhance Your Outdoor Space

Once your barbecue is built, consider adding outdoor patio furniture for a complete entertaining area. Outdoor lighting can extend your cooking hours into the evening, and outdoor heating will keep guests warm on cooler nights.

Don't forget garden supplies for maintaining the surrounding area, and outdoor decor to add personality to your backyard oasis.

Frequently Asked Questions

What type of bricks should I use for a DIY barbecue?

Use fire bricks or facing bricks designed to withstand high heat. Regular building bricks may crack under the intense temperatures of a charcoal fire.

How long does the mortar need to cure before using the barbecue?

Allow at least 7 days for the mortar to fully cure. For best results, keep the structure slightly damp during this period and avoid any heat exposure.

Can I build a brick barbecue without a concrete foundation?

A solid foundation is essential for safety and durability. A concrete base prevents shifting and cracking, especially in freeze-thaw climates.

What size should my DIY brick barbecue be?

A standard size is about 60 cm wide and 40 cm deep, which accommodates most grills and allows for even cooking. Adjust based on your available space and cooking needs.

Do I need a chimney or flue for a brick barbecue?

An open-front design doesn't require a chimney, but adding a small flue at the back can improve airflow and reduce smoke in your face while cooking.
