I have a house that has a large patio. My family is expanding and I want to use part of this for an additional room. The patio is a funny triangle shape and if I am going to do the work I want to maximize the return in both size and resale value. I currently have a flat roof over the patio. I am curious if anyone has any ideas if I want to square the area off.

Will it be easier to add on to the originally flat roof, add an addition roof at a higher level, or anything that might apply? I wouldn't mind any different ideas. If things work out properly I want to make this area a bathroom so any kind of glass ideas would be neat.

If I were to square the whole area off it would be 23'x20'x15'. With the long end running parallel to the existing house.

I live in south Florida so hurricane ratings apply. I appreciate all of your help.
