Hi all, in have a 1930 semi detached and I am looking at taking down a wall upstairs. The wall in question separate's a single toilet from the bathroom which also has a toilet bath etc. Apparently this used to be thing back in the day but to me opening it up to make a larger bathroom makes more sense now. Anyway I drilled a test hole through the wall and to my suprise found it to be orange dust. It quite easy to drill through so not sure it's actually brick?? There is no wall under this wall and it is within 1 meter of a load bearing wall. Also the layout downstairs is identical and this only has the 4 external walls for support. I have inspected in the loft and there is nothing above it except the normal joists which run straight across where the wall is. I am just suprised as it is a pretty solid wall for upstairs with nothing under it. It is however sat on one of the floor joist but built directly on top of the floorboards. Any advice on weather I need to support the ceiling/loft floor when this is out or will it be fine to come down?? I've attached a pic of the floor plan's upstairs and down to try and make it clearer. Wall to come down is in red. Thanks in advance.
