I have a sunroom off my kitchen that I'd like to make into a sitting area with direct access from my kitchen. It would involved removing an exterior wall between the kitchen and sunroom. I would also remove a sliding glass door that now acts as the entrance to the sunroom.

The sunroom is currently insulated on the floor. I'm not sure about the ceiling or walls. I attached a picture of the drawings from the initial permit (we didn't get it built, it was there when we bought the house).
