The second story is up! This floor is the master suite addition, guest bedroom, new guest bathroom, and a remodeled kids' bathroom.
The challenge with every home remodel is the intersection of new and old. On the first level, that trouble spot was aligning the floor of the new structure to the precise height of the old (which is, of course, not level) because we're going to have hardwood that patches in to one continuous floor surface with no transitions.
On this level, the challenge is a long hallway that starts in the old house and bisects most of the length of the new. The old section of hallway is not completely parallel to the exterior walls. We can't angle the new hall to match or you'll see crooked cuts in the bathroom tile floors, and a jog in the wall just won't do.
We decided to cant the front exterior wall out 3/4" to loose some of the angle. That much can be absorbed by the plywood and stucco. Then we framed the new hall walls parallel to the exterior walls and a hair wider than what we need them to be so the sheetrockers can float more mud at the joint of the two sections to give the impression that it's always been one long fabulously straight hallway.
