Hopefully I can explain this good enough for everyone to understand. The front part of my house is two story and the back then starting in the dining room its one story. The steps is between the Livingroom (two story) and diningroom (one story) there is a doorway coming off both sides leading to the steps. I am closing the doorway to the living room off, and I want to open up the dining room side and install a nice banister, (cut out a part of the wall to do this) BUt that wall is a weight bearing wall, ( I do believe since it is the outside wall on the second story. Can this be done???
It sounds like you'll be opening up a wall that has a floor load and a roof load above it, is that correct? How large is the opening going to be? It sounds like it can be done but in any case you would need someone to spec the building materials for you.
