How much does a cob house cost?
Ianto Evans has been quoted with the best answer to this question that I have ever heard; “How long is a piece of string?” Really though, your cob house can cost as much or as little as you have to spend on it. The basic materials, clay, sand and straw are very cheap and you may even be able to get most of them on your own land. Huge amounts of excellent, often brand new, building materials are thrown into dumpsters every day. I have found porcelain sinks, entire boxes of marble tile, endless amounts of high quality lumber, and every other material you can imagine for free. Because cob is so malleable, it is very easy to use odd salvaged windows, doors, and wood, so if you take the time to scavenge you may not have to buy much at all. Some cob homes have been built for as little as $500 and many for as little as $5,000.
