I like a fireplace located high on a wall. it can be appreciated from more vantage points around the room and from other rooms. This is a really good idea for a fireplace in a dining room where it still can be seen after people have been seated.
the fireplace is the focal point. There is a big contrast from the mostly white room and the dark, somewhat shiny fireplace. The partial wall behind it also frames the fireplace, making it the focal point.
