Framing up and braced
Gosh, there sure are a lot of windows! Note to everyone out there, windows take a LOT of lumber to frame in, make sure you have very detailed plans on location, height and how your king and jack studs sit in the wall before you order your lumber. And please don't forget your cripple studs, they are the structural members that will catch your sheathing ends.
Mistakes aren't that financially costly at this stage if you catch it but they do eat up a ton of time if you have to cut something out and redo it.
Not that we would know about that! : )
