I use my sunroom in the early Spring for my plants once they germinate from seeds and have a couple leaves. I set them on a table near my sliding doors which face westerly, and the sun is from that angle through most of the afternoon at that time of year. I also have those gas filled windows, but the plants seem to be happy anyway. I do see you're in Pa, so you need to take them back in on those real cold nights, unless you have a real insulated place. It works fine for me every Spring for that purpose.

Your window treatment sounds wonderful. If my ceiling were level, I'd be using the long rods to put drapes in the corners and middle to pull closed over sheers. The linen I'm considering, I have two panels in the natural that I tried in my master bedroom. They are significantly more substantial than the crinkled voile up now. I think they'll do a better job of filtering light. The spacing between the windows isn't consistently the same, so inside mount, rather than outside, minimizes the imperfections. These photos show the problems. The first is the slider and narrow window on a slightly sloping ceiling. The long wall window frames aren't even the same height. This, at some point in time, had been an exterior open porch. I'm going to do something different to cover the slider--mounting a draw curtain or shade above the trim to even it up with the window. The ceilings slope on each end for roof drainage. The other end of the room, behind the daybed shows the windows are straight, but the trim above isn't. The old board ceiling is charming, so I didn't update it.

We have a Champion 3 season sunroom. We live in Indiana it is blistering hot or freezing cold here. And sometimes all within the same week. It was pretty expensive. We thought we would be able to use for at least 3 seasons . No if it is too cool( in the 50s ) and you use heat, it sweats. If it's hot outside. You can't afford to cool it. As it leaks air so bad. We fight wasp out there all the time. And you can't have nice furiture out there because of all the dust. ( we live rural )Ours has turned into a dream turned night mare. I would put my money into a conventional room addition. I wish we had. Now we are trying to decide if we should try to salvage the floor and rebuild the walls and roof ourselves. Or call it a wash and tear the entire thing down. Good Luck with what ever you choose.

Also why are there no windows in the kitchen? Why is the foyer almost as big as the living room and the dining room? Why is the dining room so far from the kitchen? What is the space between the kitchen and the family room going to be used for? Why two staircases going upstairs in what is not a mansion? Why are there only windows on one wall in the living room and the office?
