We are swapping out the current joist on our stairway for a bigger one 2x7 instead of 2x6 as we are making the head clearance more.
however, we’ve seen something a bit worrying. It appears that this joist is not sitting on the brick wall… and the whole dining room ceiling is being supported by one nail… please tell me I’m wrong?
That 127 Cove you see is where we chiselled some back plasterboard of the coving which is from the ceiling in the living room, as we didn't realise it was the living room at this point!
There's a 2 brick thick wall running under the stairs (I think they removed a brick and a half to cater for the stairs going under the wall), and the long joist going along the stairs is supporting perpendicular joists holding the dining room ceiling. We want to swap out this joist with a slightly higher joist as we are increasing staircase clearance height to 2m (was 1.5m) but the long joist doesn't seem to sit on the actual brick wall.. and we are a bit worried if this is ok and if we can continue tbh
