Building with bales of straw has become almost mainstream in some parts of the country, especially in the Southwestern United States. Many localities have specific codes for strawbale construction, and some banks are willing to lend on this technique. Straw is a renewable resource that acts as excellent insulation and is fairly easy to build with. Erecting bale walls can go amazingly quickly. However, the rest of the creation of the building is similar to any other wood framed house. In fact strawbale houses typically only save about 15% of the wood used in a conventionally framed house. Strawbale is a good choice in realatively dry climates and combines well with cob and other natural building materials.
