where 2 roofs meet detail

Hi 

 

Little confused on this area ive highlighted with a circle on the architects drawings. Ive included the SE drawings as well. Im building the walls of the extension ( extension being the part with the apex window) and looking at it as my new roofs eaves are higher it looks like that little corner needs to be brickwork ? Although unsure of this as don't think anything below to support it. Beam 9 ? Im not at that point yet but starting to get near ! Thanks all

The loading there is minimal. However, B9 could be designed to allow for a bottom plate of which that would pick up the cavity wall construction over.
