Hey, I have a project that needs to start being planned. The idea is to tear down/open a wall behind my staircase.
I'm thinking of leaving a part of the wall (about 40-50cm) at the lower part of the staircase; on the other side, I'll keep the wall to the right of the door opening (about 10cm), maybe also leave a portion of the upper part of the wall at the same height as the door opening so that it becomes a large "arch."
The question is what is required to make this possible, does the wall support the staircase? Is 40-50cm of wall at the lower part enough to keep the staircase in place? An extra post?
