Hello All,
I am working on a grant for an organic farm school that I work at near St. Louis, MO to build a cob garden tool shed 12'x 12'. Unfortunately due to time constraints I am not finding the information I need quickly. I need to find out the ratios of sand, clay, straw and water to build a cob shed of this size. I need to know amounts that should be used for a shed this size. The idea is that it would have a large overhanging roof to cover a vegetable washing station. It would have running water, and the roof would be for water catchment as well.
The initial information that I have is that the sand:clay ratio is 3:1. However I am still needing to know the amount of straw. For this size building I have listed as 30 tons of sand, 10 tons of clay, and 13 tons of gravel for the foundation. I need to know how much wood, and of what sizes, etc... so that I can price that out as well. This would include one door, and one window. I have the costs for both of those.
If anyone can help me please contact me as soon as possible!
Thanks everyone.
