I live in a 1920's 2-storey semi-detached in Toronto. The house is brick construction with a flat roof. I want to remove a wall in the dinigroom which will expose the staircases going up to the second floor and going down to the basement. The wall runs parallel to the floor joists. My floorplan looks exactly like 'STRUCTURAL QUESTION' - Posted by: salami3 on Fri, May 14, 10 at 16:12 in this forum, EXCEPT THAT MY WALL RUNS IMMEDIATELY UNDER 'B'. There is no similar wall or posts under this wall in the basement. The basement is completely open without any support posts. There is no wall or support posts above this wall on the second floor. Can I remove this wall?
