Traditionally, fireplaces were considered to be the optimal central element to the living room, but in modern homes, this is unlikely to be possible resulting from space limitations! But it's important to remember that the objective of your living room is to be inviting to people, for getting them to feel comfortable and relaxed, and stimulate good conversation. So, even without a central fireplace, making the fireplace some sort of centerpiece will also work well. Mirrors are a wonderful tool to enhance Feng Shui in a living room. They bring light into darker areas and may reflect aspects of the area that visitors may well not otherwise enjoy. Mirrors make rooms look larger (and lighter) and very usefully, they may reflect the door, so any seating that cannot face the doorway can still have the door visible through the use of mirrors. Again, we need to adapt this principle to modern cities and homes, even though the best placement for a mirror is when it can reflect a gorgeous view.
