My Living room is 14 mt2. It has a chimney in one of the corners and a nice window on the largest side. I'm planning to have a hardwood floor with a diagonal design that points to the chimney. On the wall opposite to the chimney I am thinking to have a four tier library. I would like the room to be dark Green and I would like a wallpaper that would have some sort of 3D optical illusion. What sort of sofa and chairs would you suggest? Any ideas about the wall paper?
