Thanks guys, Very helpful information. When I get home I'll try the just pulling it up in an elevation view.
To give more information the block wall is actually split-face cinderblock, and is not solid. The wall itself measures about 40 feet by 3~4 feet, There are actually skylights on top if you look up through the center of the wall.
I understand just inserting openings and fireplaces, thank you, I see it's just like working with any other wall.
My other question would be how to anchor the roof to this, if you look at the front of the house picture the roof on the left is actually lower then the one on the right, exposing a lot of the cinder block wall. How would I do this in CA?
When I try to build the roof it always tries to connect the two roofs on the left and right, when they actually have no relation.
Side note, I'm sure you guys already know this, but this block wall has caused all kinds of water damage, In general I would now say it's a bad idea to have a 1 wythe wall.
