Good afternoon,
I am doing box dormer loft conversion on 1930's terraced house. I was wondering what is the maximum height I can place the RSJ at? I am making a cold roof so there won't be any insulation on the dormer joists and therefore I would like to get as much height as possible by placing the RSJ as high as I can. Would be my sketch correct in assuming that the brickwork on the top of the party wall should be removed? What is going to be taking the horizontal load imposed on the ridge beam?
Thank you very much for your help.
