I am trying to decide whether to repair the upstairs in my house or just close it off. The house was built in 1935 and from the height of the ceilings upstairs the previous owners just took in the attic to make 2 bedrooms. Maybe 6.5 ft tall ceiling at the center point sloping down to about 3.5 ft. My house was damaged big time from hurricane Ike and I have been working on it slow but steady. I have read that you don't want to change too much in a house this old because of it needing to breathe and historical significance, etc. Does anyone have any suggestions?
