Cod: Building Material Made From Clay, Sand and Straw

Houses built in Britain since the 15th century with clay, sand and straw called “cob” still stand today.

Cob is an inexpensive building material. If you do all the construction your self you can save a ton. Of course, you can always call a cob contractor. Which could cost as much as wood build House, you could also have trouble getting a bank to give you a loan.

Earth is non-toxic and completely recyclable. Now that's going green. Call over your friends and have an old fashion barn raising party. Every one of all ages and no experience can help.
