Planning error GU - Ceiling height

Thank you for the explanations. So, the ceiling is apparently 2.60m throughout the entire house after the floor is in. The mistake was acknowledged that the exit point was not chosen well. The pipe and these lines for the solar parts come down in the middle of the ceiling, but fortunately close to the wall. We have no choice but to either fully lower it, then the spotlights have to go in there, or a "nice" box will be attached that only contains these three spotlights, which then illuminate the shower, wall, and toilet.
I'm glad they are not making any major defects and that someday we will be seen on RTL II.

Best regards!

What ends up on rtl2 and similar channels are structures that often do not even have a construction specification or execution drawing. There, everything that can possibly be done wrong is done wrong with all the rules of the art.
