Here are lots of different pictures showing how an adobe house is built. Very informative. Gives you a feel for all that is involved in building a house.
There are many types of owner built homes. I dream of building myself one someday. My favorite is stone but there are straw, cordword and even paper.


This is a picture of a house insulated with rice hulls. Seems like the best insulation material was sitting right under southerners' noses.The rice hulls are unique within nature. They contain approximately 20% opaline silica in combination with a large amount of the phenyl propanoid structural polymer called lignin. This abundant agricultural waste has all of the properties one could ever expect of some of the best insulating materials. Recent ASTM testing conducted R&D Services of Cookville, Tennessee, reveals that rice hulls do not flame or smolder very easily, they are highly resistant to moisture penetration and fungal decomposition, they do not transfer heat very well, they do not smell or emit gases, and they are not corrosive with respect to aluminum, copper or steel. In their raw and unprocessed state, rice hulls constitute a Class A or Class I insulation material, and therefore, they can be used very economically to insulate the wall, floor and roof cavities of a super-insulated Rice Hull House...Some other information is here and this guy really has some good ideas about constructing economical rice hull homes here. If I lived in the south, I would certainly look into this. Transportation costs would be a consideration further north.

Cob construction uses sand, clay and straw. Mixed well this special mud is applied to the foundation in continuing layers. Each layer must dry so that it can support the next, and the wall is tapered in as you build up. When it is dry, the walls are very hard and load bearing. The roof is built directly on to the walls, as the walls themselves are the support structure.
