13 BEAUTIFULLY PRACTICAL Cob Ovens & How to Build One Yourself

Sharing is caring!

With rising awareness of the expense and huge environmental impact associated with modern construction, people are making a big move toward natural, environmentally-friendly building practices. Cob construction is a great example of an ancient building technique that is making a huge comeback.

These earth and straw structures are hard to miss; they look as though they came straight out of a Tolkien novel. They are durable, practical, and beautiful, each one a handcrafted work of art.

If you’d like to try your hand at natural building but the idea of starting with a large structure is intimidating, why not jumpstart your skills with something small? An outdoor wood-fired oven makes an ideal starter project that can be done in just a few days.  

These ovens are a simple technology and are easy to construct and use. Once the oven is built and has a few weeks to dry out, you use it for baking by lighting a wood fire inside the dome, which heats up the thick clay walls.

The oven will then remain warm and at a consistent temperature for hours after the fire is removed.  Cob ovens bake amazing pizzas, bread, and other food without relying on fossil fuels, and one fire will cook an abundance of food before the oven cools down.

A cob oven can be constructed out of all natural and recycled materials. Here are some great examples of the types of cob ovens people are building – from very simple dome ovens to gorgeously detailed sculptures.  Many of these pages provide excellent instructions if you want to tackle building one yourself.

The builder of this frog cob oven says the base took much longer to build than the oven itself, which was built and shaped in less than 4 hours. Very cool!  From user Castlerock on
