Unfortunately, we now had to make some concrete decisions; I therefore see no more possibilities for changes, at least not in the basic structure. As you saw in the other thread, communication is a bit difficult with us, and we had a favorable constellation where we could still get some additional changes through (e.g., a 3m lift-and-slide door instead of a 2m swing door in the living area) and a few other detail adjustments. For that, however, we had to be faster with the bathroom than I would have liked.
Of course, I’m still happy to look at other variants and maybe it will help someone later on. I just wanted to avoid you doing the work only for me to say afterwards, "I can’t implement that anyway."
