This is our now , Sun porch. We changed out the regular door with a set we bought used and put 2 of them here. If necessary the second door will open but only if it has to be. The third ” door” we turned into a window on the opposite wall that originally had nothing. That does not move. Lol then we took out all the ceiling boards and found just lots of just waste so took it all out and insulated ceiling. It adds about a foot of extra space on one side but makes a huge difference. Now I need to get something to cover them up when it gets really hot but it helped with oil this past winter!!!
