Our current plan is to burn the lath this winter, bury the plaster at the bottom of the hill in the backyard and dispose of the rest. We've spent a lot of time pulling nails and sifting thru the mixed demo waste on the floor and we stopped generating more waste until we figured out how to dispose of it.
Also, we haven't covered the hallway floor yet. I think we've got everything figured out now and we just have to figure out how to get the materials we need. I really miss having a vehicle that could haul a piece of 4'x8' material. Sigh.
