We need the execution planning because too many errors occur and there are constant discussions about walls, doors, solid or drywall construction. It is a semi-detached house (or is supposed to become one), the wall between the two houses is solid in the planning. On the upper floor, the wall was already fully built and has now been partially removed again (between the two bathrooms) because the BU on site found that the staircase is under this wall and the wall is too heavy for it and now drywall is supposed to be installed there, which in my opinion is not acceptable, especially because of the sound insulation.
