The whole carport/garage was already made of concrete block. The previous owner just filled in the 9' spots with wood framing instead of using block the first time around. It was already built on a slab with all concrete walls, and one side of it is my concrete block house. I can only assume the slab was poured to the correct thickness during the original build. I have attached some pictures of the filled in side where a old door used to be.
I basically want to do the other side with block, but leave space for a window. I also want it to look like the rest of the windows in my house. I'll take a pic of what they look like later today.
Once the side with the window is complete I'm going to re-stucco the whole wall. Hopefully you won't be able to tell there were ever "cutouts" there.
