Thanks. That's very helpful. I wasn't sure if I was allowed to cut the wall plate (I thought I had read somewhere that they should be a minimum of 3m long ie. continuous). But that's great. And thanks for the advice on the valley. Cheers.

Thanks! I was hoping that would be the case.

Thanks. I guess I may need a structural engineer at some stage. I was just hoping, in the first instance to understand some building principles (like, can I brick upwards from a wall plate, or is that a no-no) and to pick up some experience from the builders on this forum, as I guess some of you guys will have come across this issue before. Cheers

Hello. I wonder if anyone can help me, please? My house is a little unusual. It comprises a small bungalow and a small two storey house almost side by side with a 2 metre wide flat roof section joining them together. I have planning permission to extend the two storey part over the flat roof. But that would involve extending one of the walls upwards, and that wall is already carrying the bungalow roof. Is it possible to extend the wall upwards with the bungalow roof trusses still embedded in it? I have included a sketch to make things clearer. As you can see, the wall plate for the bungalow is on the “inner” skin but if I extend it upwards to also carry the new two storey roof, the additional wall plate will be on the other skin. I guess I may also have an issue as to whether the foundations can carry the load of two roofs? As you can probably tell, I am not a builder – any advice would be appreciated.
