While Mark kept working on the ceilings, I set to work on the fire wall that will surround my wood stove. Mark is working on the bathroom ceiling so no tiling until he's finished. Blocks I am using are timbercrete blocks leftover from building. These blocks are made from waste cypress pine sawdust, sand and cement. Great product but the guys selling it leave a lot to be desired (subject for another post). These blocks are fireproof. There will be a stainless bench near the wall and a slate floor underneath.
