There are a variety of options when it comes to how the structure, or base, of an outdoor kitchen will be built. The materials selected for an outdoor kitchen must be able to withstand high temperatures as well as a variety of weather conditions. Framing options include concrete block, brick, wood or steel. The construction of an outdoor kitchen can be a complex process. For safety and durability, it is essential that construction be carried out properly. Prefabricated outdoor kitchen kits can be purchased if you wish to avoid detailed construction. While each outdoor kitchen is unique, the construction process is relatively uniform whether it's built out of wood or block or even a framework kit.
