A strawbale home is one built of small square bales. they can be load bearing ie (hold up the roof) or they can be used as infill in a post and beam frame. We did the post and beam frame thing.
the exterior is usually cement stucco and the interior also has a plaster finish of some sort .....we used white cement inside.
they are very warm, and very strong, and surprisingly very fire resistent (after stucco of course) but even before stucco bales unless kicked apart dont burn very well. You farm guys will know what I mean.
