Our house had an addition added on the back of the house before we bought it. We are currently updating the house. We have removed paneling and also removed the old windows that used to be at the back of the house before the addition was built. Now there are just 3 large holes in the wall where the windows used to be. I like having it "open" so you can see in the back room, but really don't know what I could do with these openings. Build them up 1/2 way up so the openings are not so large?
