I have a typical 200 year old 45 degree kent peg roof. I am fitting a loft room, essentially insulating and plasterboarding the entire triangular cross section (not bothering with knee walls) and a very small ceiling. I want to keep it as a toblerone shaped room.
Half way down I have to build a stud wall to enclose an en suite bathroom.
My question is, do I fit my 4x2 frame up and under the rafters to help support or do I put my 4x2 frame alongside the rafters and fix my wall to the rafters from the side.
Is there a preferred method? I'd like it to be strong and last and I am a little worried that a roof that will flex with temperature and winds will crack my paster, particularly at the corners where roof plane meets stud wall for example.
