For the next several weeks, I plan to blog about a variety of green and natural building methods. Each will include a short summary of the method, plus links for those who are interested in learning more.
Building with adobe is roughly equivalent to building with brick or cinder blocks, but adobe 'bricks' can be made yourself. Adobe is basically a mixture of clay (the glue holding everything together), sand, straw (or other fibrous material) and water. When you think of a sand castle, sand doesn't seem like a strong building material. But there is more sand than clay in adobe.
