My lad has just bought a 70's house, and all the upstairs walls are those very thin walls (like a 2x2 with plasterboard on each face). He wants to remove one such wall, which runs at right angles to the ceiling joists. I suspect due to the puny nature of the wall, and the fact that there's a 1m wide break in it, it's not likely to be doing anything structurally useful in terms of the roof. However I'd welcome any advice. Loft pic attached. The wall runs parallel with, but not directly under, the big timber that you can see runs across the loft floor. I suspect this timber is also spanned accordingly to bear the weight of the upright (king post?) timber thats bearing down onto it - but may be wrong. Thanks!
