Working through a remodel that basically turned into a rebuild due to issues we found once the walls were opened up. Originally we planned on patching the existing siding around the new windows but as you can see we basically ended up replacing all the siding on the front of the house. The sides and back have more of the original siding intact. If I could do it all over I'd do all new siding since we ended up replacing over 50% but it is what it is at this point so I'm trying to make the best of it.

  
The siding is T1-11 (yuck I know, but the original lasted on the house for 45 years with basically no issues) 8" OC. We are planning on painting the siding+trim a dark green to allow the black window and stained wood accents to pop (see the architect's rendering). We are going for a mix of modern mountain with some craftsman elements (the 3x1 window SDLs) to make the best of what we're working with.

  
It's time to figure out the window trim on the exterior. Any suggestions on what to do in terms of thickness of the sides, the top/bottom, and whether to have a sill or not? We have a lot of different sized windows (more so on the other sides of the house) so I am unsure if one size fits all for the trim pieces.

  
We were also thinking of using some longer thin trim pieces (perhaps 2x1 FJP) every couple of T1-11 seams to create a bit of a board and batten look without going all the way. If we do this we would also lay some horizontally on the front wall to cover the horizontal seams in between the T1-11 sheets. 

  
Any thoughts/suggestions are appreciated!
