Your own outdoors pizza oven is a great idea, especially if you love pizza and frequently make it.
Before you get started building your own pizza oven though, it's good to know that it's a whole different experience from making pizza indoors - it requires a bit more time to get the pizza out and so you have to make some good time each time you want your outdoors pizza treat.

If you want to make it really easy on yourself, make sure that its not near anything that can burn easily, like grass that dries out a lot in summer.
Here's what you do to make an outdoors pizza oven:
1. Before you build your own pizza oven, you need to decide on the size of pizza oven that you want. At the place where the oven will stand, dig a pit that's as wide as however many pizzas you want to be able to accommodate at once. The pit itself should be 5 inches deep.
2. Line the sides of the pit with wood, and then over that and on the floor of the pit, put in concrete until the hole is full. Let this dry out. To make sure that you get it really dry and hard before you continue.
3. Its time to build the upper encasement, and to this, you should draw a line on the concrete where you want the encasement walls to stand and then add an extra couple of inches on each side. Now lay out your concrete bricks in whatever shape you want to build your own pizza oven in, Wait for these to dry and then add the other bricks to the outside of the concrete bricks and pack them tight using mortar.
4. You need to make a wooden support on the inside of the dome using 2x4's and plywood, so that you can make the bricks to line the inner part of the oven.
5. As you line the bricks on the inside, make sure that you leave enough room to slide pizza in and out, but not too big that you'll be losing heat through it.
6. You can do the final touches to your style. Use the template to guide you as you lay on the top part of the oven, making sure to let all the finishing touches dry. Don't rush them as a fault in these can lead to a fault all the way through the oven.
7. Stack the bricks outside of the oven, leaving a space to act as a chimney.
You need to let everything dry completely before you start baking. If you use your pizza over before its dry's, it may collapse. The best way to make it completely strong and dry is to fire the oven with small fires for some time so that all materials bed together. You will have built a pizza oven that can serve you for many years.
