Window framing and pony walls

[IdahoJaci]

I have exterior pony walls.  The rock extends out farther than the wall above.  No problem so far.  I want 4.5" deep window sills on the inside.  When I set the window to be aligned with the exterior wall I get proper trim until it gets to the pony wall.  If I set it to be flush with the inside wall, I get about 1" window sill and the outside has framing showing at the pony wall.  I do have 6" exterior walls.

 

I really don't care about all the building stuff in the middle of the wall.  This is only for aesthetics - placement, style, color, etc.  It is not for plans, or structure.

 

Where do I make corrections so the window shows with a 4" inside sill and sitting correctly on the exterior wall?  Do I change the size of the building material within the wall within the wall specifications?  Do I change something with the window?  Do I change the lower rock wall to only 1" thick so it matches the upper part of the wall?

top left pic looks good?

 

What type of windows? wood, vinyl or aluminum framed?

In PRo versio You have control over int & ext sill, header, casings, jamb etc.

 

play with them until you get what you want

 

Way it is made would be the windows installed before siding be it board batten on top or the stone veneer on bottom.

Each will have a detail on how it ends near windows and doors etc.
