I am planning to build a workshop. The dimensions are 10x5x2meters. It will constructed in block with a rendered finiish and a tiled roof. What I need to know is how deep the foundations should be and is their a formular to work the depth and thickness out. Also it will be single skin, so how do I damp course/proof it or does the render waterproof it?
Any help would be greatly appreciated.
Many thanks Lee. :?:
