Fireplace Ideas
This is what an accent wall would look like, and then you could always add a mantel to break up the area between the fireplace and tv. But notice the size of this fireplace, this is what I meant at your house by seeing if we could make the fireplace longer but I'm not sure. I've already emailed the builder asking him.
Another idea but since you can't have your fireplace up and the wall back, you would have to paint an accent wall and put the tv higher up than what it is to the left or right; or you could add a top mantel and put up there.
