Framing
A few considerations I had during framing were
Whether to use steel or wood studs (probably should have used steel for the areas furred out)
Ceiling heights -I could have taken the ceiling higher in both the hallway and bath, but felt that choosing a height that was a little lower than the high points in the bedrooms was the best.
How to get a look where no baseboard would be used – I considered drywall options and went with a something I came up with where I notched studs and then ran backer in the notch to facilitate a stronger base.
