Depending on where you live, perhaps an earthen home can meet your requirements? They're dirt cheap to build (excuse the pun) and apparently require very little expertise. It's something I've been researching. Personally, I love the way cob homes can look; it's probably the hobbit in me.

Are there any threads on housing? So far not able to find any. I am looking to buy some good farmland but will need to put a house of some sort on it. Some ideas I'm considering:
