Door frame and new windows, and a wall to work around

[vishusingh]

Hey folks …

 

im probably overthinking this….

 

I’ve a non load bearing wall with a door on a 1969 extension 

 

were moved away from knocking the wall down to build a timber frame and house the door and windows in a more traditional way to the standard window door window ie flag door flag

 

question is- when the door is removed from the existing space, I need to knock out about another 600mm of wall to the right and then be able to seat the door and windows together so how do I finish the area above? It’s about 9” and I’m just wondering if I somehow make a simple wooden frame with a 9” double header to hold the section cross joints above…

You could just box in above the door, insulate and membrane but you will have to clad the exterior for weather protection. 
on the other hand a 9 inch “T” lintel with brickwork to match on exterior. Depends how much you want to put into it.
