Drywall
Work with your framer, to set aside a large hole on each floor, for drywall to be INSERTED by elevator device.
My house was 3 stories high, that the men had to HAND CARRY drywall, 1 or 2 sheets at a time… hand carrying up 3 flights of stairs… when it could be inserted INTO the house by machine. It was just inhuman, needless drudgery…..
This just takes a bit of forsight and coordination to leave large windows, or holes on each floor.
