I am looking to buy a house that had a built in wood wall cabinet placed over the wall and a fireplace. I want to remove it. 1. Is doing something like this as simple as just cutting away at it? What is involved with doing this? 2. Obviously we have no way to know what will be behind the builtin after we remove the built in, though what types of issues might we have to address after removing the built in? Could it have caused any problems by having it placed there? Thanks!
