I've been thinking of adding on a sunroom sometime this summer. That said, has anyone else done this recently? If so, could you share your experiences with the process? I'm just in the beginning stages now, so haven't done much more than look at some pictures. I'm not even sure if it will be a three or four season room at this time, though to save some money, it will probably end up being just three. Anyway, I already have a 15 x 15 patio off the kitchen, so the base foundation is already there. If you or someone you know has recently done this, I would certainly appreciate your thoughts. Thanks.
