First I'll show you the construction site and the plan of my masonry.
My trainer has suggested that I should practice how to build a roll layer on top. This layer is not really important for the PMBC course, but I think I can learn something extra from it, don't I?
In the ground plan you can see a wall corner, one side is 1,74 meters long, the other is 0,99 meters.
My trainer told me, that the wall should be 24 cm thick with a height of 0,75 meters. In addition, there is the 12.5 cm high roll layer. I'm supposed to use NF stones (240 × 115 × 71).
Check the sketches below, please (ground plan, frontview, isometry).
