Well, all the fine details. Connections from exits to the terrace, how the ledge on the cistern runs into the windowsill, where the awning will be drilled in. What is not clearly specified is done according to the "Schonimmerso" method. And then the tiles end 3 cm above or below the door frame - simply because every craftsman does what he thinks is right and no one sees himself "as the guardian of his brother." According to the norm, no defect, but it looks off-putting.
Hmm, the terrace is not planned yet at all, we'll do that ourselves later. There won’t be an awning. The windows will get normal windowsills, also DIY, because we still have great ones made of granite (if we can get them out of the old house intact). But there will be an execution plan, said the builder. I think such things will be clarified then. When I look at finished houses from the builder, "Schonimmerso" seems to work very well.
