So we have a late 60s 2 story home. We have 14 stairs from main level to the 2nd story. On one side of the staircase it's open for the first 5 stairs then the wall starts. On the other side it's all wall with out livingroo on the other side of the staircase wall. We are wanting to open te living room side to match. I looked in the basement and they doubled up on the floor joist on each side as shown in my Pic. Would they have framed the the main level the same,making it safe remove the part of the wall like we are waiting
