Placing one roof under another

[Flanderosa]

Hi there everyone

I have attached Photos (1-3) showing what I want to achieve.

Photos shows where I'm up to. Photo 5 shows what happens when I try and extend the eave (which the new roof will sit under).

Does anyone have any idea how I can move forward?

Hi - I modelled something from your pics to see if I could basically - so it can be done;

I show blockwork not brickwork walls - sorry; 

Need to sort out the brick coursing either side of the wall junction;

Have a go using soffit for the beam and partition for the expansion seam;

Good luck.

Jeff.
