This is an example of mirrors that WORK on the stairway. They actually reflect something of interest instead of another white wall or a blank ceiling. Reflecting another piece of art, a view from a window or a beautiful room is always best though. Be careful with mirrors!! It's not all about their frame!
If I end up in a small house, I'm seriously considering not having a couch. I love this arrangement of chairs around the fireplace. To conserve space, I could mount my TV over the fireplace and just have 2 chairs w/a table in between, facing the fireplace and TV. Like the built-in bookshelves on the sides too.
