Although I doubt that right now since the stones are 2.5 cm thicker than in the plan. I want to go there again tomorrow and measure everything.
40cm should maybe be 36.5 + 2*2 cm plaster.

Since the shell builder acts as the general contractor, hopefully that won’t happen.
You should have questioned the even numbers ;)
Next house then. The first for the enemy, the second for the friend...
