Constructing of a wood burning oven from a kit may seem a daunting task, but anybody with some basic masonry skill can accomplish it with relative ease.
The tools needed are available at most hardware stores, and a medium size oven can usually be built in a week or so, weather permitting!
The starting point of a structure that could weight well over 2000 lbs. is a reinforced concrete slab and a reinforced block wall. On that wall you will need to build a concrete reinforced base, at least 7 inches in height.
Above the reinforced base you will need an insulation layer; you can use around 4 inches of insulating concrete or fiber cement boards; they are both commonly available and will allow you to increase or limit your base height.
Place the oven floor on the base of the stand, ensuring the oven will be centered and all the materials width are accounted for. Using refractory cement, secure the floor tiles to the base, ensuring they are level.
Place the dome elements on top of the base, cementing them together. DO NOT USE CEMENT BETWEEN THE DOME AND THE BASE OF THE OVEN.
Cover the dome with 3 to 5 inches of insulating concrete, ensuring the dome is not cemented to the base.
Cover the dome with a thermal insulant such as rock wool or ceramic fiber blanket, and wrap using soft wire mesh.
If you are going to finish your oven with a structure around it, fill the cavities with a thermal neutral material such as perlite or vermiculite, if you are going to give your oven the igloo finish, cover the mesh with cement based plaster.
