The person I bought my house from closed in what used to be the deck to form a sun room. They used plasterboard on the walls but didn't finishe it very well. I have one section of the wall, near the doorway (which does not have the wood framing finish around it) which is between studs that has started to bulge outwards. This particular section has no nails in and is about 5ft square (the middle of it bulging) it's about a foot from the ceiling. What is my best option?

I am puchasing a home that has a living room wall that contains a window (no glass) between it and the kitchen. I am toying with the idea of taking out the wall underneath the window in order to create a doorway between the two rooms. I am almost certain that the wall is not loading bearing and that taking out the wall will not create any structural anomalies. The section in question is about two feet wide by three feet extending to the floor from the open area. How long should I expect this project to take, and what is the level of difficulty in fully finishing the project? Thanks for your input.
