By the end, you’ll have everything you need to start your own pizza oven build and enjoy the satisfaction of cooking perfect pizza in your garden.

Planning Your Pizza Oven Build Before you start stacking bricks or mixing cement, it’s worth thinking carefully about your pizza oven build. A bit of planning now saves wasted effort and ensures your oven works exactly as you need it to.

Decide what type of oven is right for you. A DIY pizza oven made from fire bricks and breeze blocks is the most economical outdoor brick built option and ideal if you enjoy DIY projects. Pizza oven kits can speed things up, especially if you’re less confident with construction, while a bespoke pizza oven gives you a professional finish and lasting durability. The choice comes down to budget, skills, and how you intend to use your oven.

Think about space in your garden. Do you want a compact oven in a corner, or is there room for a large outdoor pizza oven with a covered cooking area? Remember, you’ll need clearance around the oven for safety and airflow.

Consider size and purpose. If it’s mainly for family dinners, a smaller brick pizza oven heated with a small fire will be plenty. But if you plan to host big parties or run a hotel business, then look at building a larger outdoor pizza oven with a generous oven floor to handle multiple pizzas at once.

Focus on performance. The best pizza ovens retain heat well, reach high temperatures quickly, and stay hot long enough to cook batch after batch. That’s why refractory materials and good insulation matter – without them, even the neatest brick dome won’t cook pizza properly.

With these basics in mind, you’re ready to move on to the practical side: gathering the materials required to build your oven and preparing a solid foundation.

Materials Required to Build a Pizza Oven

Getting the right materials at the start makes all the difference to your pizza oven build. A wood-burning oven has to withstand extremely high temperatures, so this is one place where cutting corners will cause problems later. Think of it as investing in your own garden pizza oven for years of reliable use.

Here are the key materials required to build:

• Fire bricks or 2-inch refractory bricks – These are essential for the oven floor and brick dome. They’re specially designed to handle high temperatures without cracking. Ordinary house bricks aren’t suitable for the cooking surface because they can’t cope with the heat.
• House bricks or breeze blocks – Perfect for the oven base and general structure. They don’t need to be heatproof here, just sturdy.
• Cement and sand – Used to bind bricks together and level surfaces. A thin layer of sand also helps settle the oven floor smoothly.
• Slabs – Useful for creating a flat, solid base to build on. A square foundation of slabs keeps your oven stable.
• Chicken wire and insulation – Wrap the brick dome with chicken wire, then cover with insulation material to trap heat inside the oven. Without insulation, your oven won’t hold heat long enough to cook properly.
• Powder coated steel front (optional) – A neat finish that gives your oven a professional look and helps protect the opening.
• Wooden pallet – Handy for moving heavy loads of bricks or cement bags into position.

Refractory materials are non-negotiable. They make the difference between an oven that cracks after a few uses and one that will happily cook pizza for years. If you’re aiming for a good size economical outdoor brick built oven, stick with the essentials: fire bricks, breeze blocks, cement, and insulation. If you want a pizza oven with a more polished finish, you can add extras like a powder coated steel front or decorative tiles. You can get all needed materials in a specialised online shop – Vitcas.

Once you’ve gathered your materials, you’re ready to start building from the ground up – and that begins with creating a strong oven base.

Building the Oven Base

Every solid garden pizza oven starts with a stable base. Think of it as the foundation for everything else – if it’s uneven or weak, the whole pizza oven build will suffer. The oven base needs to take the full weight of the brick dome, oven floor, and chimney, so don’t rush this step.

Step 1: Choose the spot. Pick a square, level area in your garden. Make sure there’s enough space around the oven for you to move freely and, if possible, cover it later with a roof or shelter to protect it from the weather.

Step 2: Lay the foundation. Use breeze blocks or house bricks to create a strong, square structure. Cement them firmly in place so the base doesn’t shift over time. A good size, economical outdoor brick built oven usually starts with two or three layers of breeze blocks.

Step 3: Add stability. Once the breeze blocks are set, top the base with paving slabs or cement to create a flat platform. This surface will carry the oven floor, so it needs to be solid and level. Use a spirit level and adjust with a thin layer of sand or cement where necessary.

Step 4: Think about storage. Many DIY builders leave a hollow space in the middle of the base to store wood. This keeps your firewood dry, tidy, and close to hand when you’re ready to light a small fire in your wood-burning oven.

A sturdy oven base gives you peace of mind and sets the stage for the next stage of the pizza oven build: creating the oven floor where you’ll cook pizza to perfection.

Constructing the Oven Floor

With the oven base complete, it’s time to focus on the surface that does the real work – the oven floor. This is where your pizzas will bake, so it needs to be smooth, level, and built to withstand high temperatures.

Step 1: Prepare the surface. Spread a thin layer of sand across the slabbed base. This helps level out minor imperfections and provides a soft bed for the fire bricks.

Step 2: Lay the fire bricks. Position 2-inch refractory bricks tightly together to form a flat, piece round oven floor. These bricks retain heat beautifully, ensuring your wood-fired oven reaches the temperatures needed to cook pizza quickly and evenly.

Step 3: Check alignment. Use a spirit level to confirm everything is flat. Any bumps or dips will make it harder to slide pizzas in and out smoothly.

Step 4: Avoid the wrong materials. Never use standard house bricks for the oven floor. They can’t withstand high temperatures and may crack after just a few firings. Fire bricks are essential here.

A good oven floor delivers the perfect pizza and helps store heat for baking bread or roasting vegetables after the main fire has died down. With this crucial layer in place, you’re ready to build upwards and create the classic brick dome.

Building the Dome

The dome is the heart of any brick pizza oven. Its curved shape reflects heat down onto the oven floor, creating the even, high temperatures that give wood-fired pizza its unique character. Building a dome takes patience, but it’s the step that turns your DIY pizza project into a proper outdoor pizza oven.

Step 1: Create a mould. Many builders use a mound of damp sand or a temporary wooden structure as a guide for shaping the dome. This mould sits in the middle of the oven floor and supports the bricks as you build upwards.

Step 2: Lay the first layer. Start at the base, placing fire bricks in a circular pattern around the edge of the oven floor. Angle them slightly inwards as you go, using cement to hold them in place.

Step 3: Build upwards. Continue laying bricks in overlapping rows, gradually moving towards the middle. Small pieces of brick can be used to fill awkward gaps. The aim is to form a smooth, continuous curve that closes neatly at the roof.

Step 4: Add reinforcement. Once the main brick dome is complete, wrap it in chicken wire. This provides a frame for the insulation layer that follows.

Step 5: Insulate. Cover the dome with insulation material, then add a cement coating to lock it in place. This step is crucial: without insulation, your oven won’t hold heat for long, and you’ll struggle to cook more than one or two pizzas at a time.

Step 6: Optional finishes. Some builders like to add a powder coated steel front for durability and a professional touch. Others keep it rustic with plain bricks or render. Both approaches work – it depends on whether you want a simple DIY pizza oven or a pizza oven with a more polished look.

A well-built brick dome is what makes a garden pizza oven truly shine. It captures and radiates the heat from your wood-burning oven, turning a small fire into the consistent baking environment needed for fantastic results. Once the dome is finished, the next step is to add a chimney and bring the structure together.

Chimney and Finishing Touches

With the dome complete, your outdoor pizza oven is nearly there. The next step is fitting a chimney. A chimney is more than decorative – it controls airflow, draws smoke away, and helps your fire burn hotter and cleaner.

Step 1: Position the chimney. Place it at the front of the dome, above the oven opening. This spot ensures smoke is channelled away without pulling too much heat out of the brick pizza oven.

Step 2: Secure in place. Use cement to fix the chimney tightly. A simple flue pipe works well, though you can upgrade to a powder coated steel front with a fitted chimney for a more polished finish.

Step 3: Seal the dome. After the chimney is in place, coat the entire dome in a final thin layer of cement. This locks in insulation and protects the structure from weather.

Step 4: Consider protection. An oven in your garden will face rain, frost, and sun. Rendering the outside, tiling the roof, or placing the whole oven under a covered shelter will add years of life to your pizza oven build.

Once the chimney and finishing touches are complete, you’ve got an outdoor wood-burning oven that looks the part and functions as it should. The only thing left is to light it up and start cooking.

First Fire and Cooking

The first time you light your oven is exciting, but patience is key. Jumping straight to a roaring fire risks cracking the dome or damaging the cement. The trick is to cure your DIY pizza oven slowly.

Step 1: Start with a small fire. Build a gentle fire in the middle using dry wood. Let the heat rise gradually. Keep it going for a few hours, then let the oven cool. Repeat over several days, building the heat each time. This process dries out the cement and strengthens the refractory materials.

Step 2: Work towards high temperatures. Once cured, your wood-burning oven should reach the 400–500°C range needed to cook pizza in just a couple of minutes. This is where your fire bricks and brick dome earn their keep, trapping and radiating heat evenly across the oven floor.

Step 3: Choose the right wood. Hardwoods such as oak or ash burn longer and hotter, perfect for pizza. Avoid softwoods – they produce too much smoke and don’t deliver steady heat.

Step 4: Cook beyond pizza. While the perfect pizza is the highlight, a garden pizza oven is more versatile than many realise. Use the residual heat after cooking pizza to bake bread, roast vegetables, or even slow-cook meat. A good size, economical outdoor brick built oven will hold enough heat for hours of baking.

Once you’ve mastered firing and cooking, your outdoor pizza oven becomes more than just a project – it’s a centrepiece for garden gatherings, a practical tool for baking, and a source of fantastic food.

Tips, Tricks, and Common Mistakes

Building pizza oven projects can be hugely rewarding, but a few simple errors often trip people up. Knowing the pitfalls – and a few clever tricks – makes the difference between frustration and a garden pizza oven you’ll use for years.

Common mistakes to avoid:

• Using the wrong bricks. House bricks are fine for the oven base, but never for the oven floor or dome. Without refractory materials like fire bricks or 2-inch refractory bricks, your oven won’t handle high temperatures.
• Poor insulation. Skipping insulation around the brick dome means the oven loses heat quickly, so you’ll struggle to cook more than one pizza before the temperature drops.
• Lack of space. Cramming an oven into a tight corner makes it awkward to cook and harder to keep safe. Always leave enough room around your outdoor pizza oven.

Tips and tricks:

• Keep a thin layer of sand handy to help level surfaces, especially when laying the oven floor.
• Use small pieces of brick to fill gaps in the dome – this strengthens the structure and helps create a smooth curve.
• Build storage space into the oven base to keep your wood dry and close to hand.
• Start with a small fire each time you use the oven, then build it up gradually. This avoids thermal shock and extends the life of your oven.
• If you want a professional touch, a powder coated steel front gives a neat finish and protects the opening.

With these tricks in mind, you’ll not only build a pizza oven that looks fantastic, but also one that’s practical, durable, and easy to use.

Conclusion

A DIY pizza oven isn’t just a weekend project – it’s an investment in food, fun, and your garden. From laying the oven base with breeze blocks to shaping the brick dome with refractory materials, every step is about creating an outdoor wood-burning oven that suits your space and needs.

Whether you choose a good size economical outdoor brick built oven for family meals or a large outdoor pizza oven fit for a pub or hotel business, the principles stay the same.
