Big Al, thank you for your reply about the papercrete:::so the floor is wood. We are laying down the treated rafters now, and then we're gonna put some osb particle board on top of that, followed by bamboo panels nailed to the plywood:::is that ok for the rocket stove to sit on or do we have to raise it off the wood floor? You mentioned vents too. Im sure the book has all this info, I'll get that tomorrow. Sorry for the confusion, just the walls will be papercrete.
My heartfelt thanks, Nila
