The bottom 2 photos show the results of pantries being removed from kitchen corners. The carbuncle on the ceiling is housing the staircase half landing turn and 3 risers. This photo is an identical house with the pantry in place. Would like to remove the pantry. So, what's supporting the staircase half landing? And what supports the breezeblock wall that runs directly above the wall that's been removed? Please could a structural engineer shed any light? Thanks.
