comment Floor joists connection to eaves
@Mike Perry I was trying to avoid attaching the new joists to the rafters at all. The existing roof structure is not being touched.

@Mike Perry Not yet, but I'm not making it a habitable room, so it only needs to pass inspection. Either way, I'm in contact with building control in my council, so they will advise me where needed.

The plaster work is brand new - I did it recently. 12mm board with plasterboard screws.

comment Floor joists connection to eaves
Ah ok. I can't rely on the existing ceiling joists as they are old, thin, and already supporting the ceiling plasterwork. What I'm going to do now is expose my eaves and see exactly how much space I've got, then draw a profile plan of the joist sat on the brick in relation to the existing woodwork.

Not sure I follow. By shearing stress I mean the forces acting downwards. The wood supported by brick is fine, but the wood hanging over the edge will try to shear away from the wood on the brick - all from the downward pressure from the floor contents. If I take a triangle out of the end of the joist, I alter the thickness of the part of the joist resisting the shearing. Not sure if I'm worrying about nothing :-)

Hi, yes that it was I think needs to occur, however does that then alter the strength of the joist against shearing on the brick face?
