Different height wall plate.

[Ureyg]

Ideally I want the wall plate sat back so it isn’t exposed too low.
Structural engineer said I can do it either way, sit on top of shorter beam coming out of extension or sat on the post, I can’t see how it would work on picture one? Can anyone help, what’s the best way to go about it?
If I did it like picture two the beam would sit quite low and be exposed.
I’ve just rested the beams roughly where they would be, obviously they’d be notched into the brickwork

I think you need to explain what your plan is a little better. Are you going to have a hip going from the top of the steel post up to the corner of the house with 2 different pitched roofs for the side and front or something completely different
