The wife wants me to remove a wall in the kitchen to open up the room. I removed some plaster board to see if it was a supporting wall and all I could see was that it was hollow apart from the top of the wall where it meets the ceiling. At this point there appears to be a beam which extends from the archway into the wall.
Looking from the outside of the house my upstairs bedroom external weatherboard wall appears to be in line with the wall that I am trying to remove. Therefore is this a load bearing wall? If it is, what do I need to do to allow this wall to be removed without the house falling around my ears. Is there a way of telling if a wall is structural or not?
