Thanks, everything but the tin sheets was free material. Those rocks were fairly useless till we decide to make use of them. Our workers are also basically one large extended family so there's a lot of bonhomie and camaraderie while they work.

We weren't too fussed about the finish cause it's a non residential building. Most of the plaster will crack, but the stone is solid and the overall look is unique. I do have to eventually build a home there and will consider wattle and daub with a lot of fibre.
