This is the cheapest and simplest to build, using rubble and railway sleepers for a base, some bricks for the firing base and clay and sand for the oven itself. If you can build a sandcastle at the beach, then you can build one of these. The disadvantage is that it takes a long time to heat up and is not big enough to keep a fire going, once you start cooking.

This type of oven takes some bricklaying skill and is the second cheapest option. Three of us took two days of hard work to build ours. It heats up in 4 hours and is big enough to keep a fire going to cook pizza all night – a few weeks ago we cooked 42 pizzas in an hour.

One of my friends has bought an Ooni pizza oven and loves it. They look great, cook well and are aimed at making pizza for your family. Our big wood fired oven takes 5hrs to get to temperature, but then we will cook 90 pizzas at a party! The Ooni oven gets to 500oC in less than half an hour. BUT it will only do one pizza at a time!
It retails in the UK at £299 and in the US at $350.
