In modern homes, this can be unlikely to be possible due to space limitations, though traditionally, fireplaces were considered to be the right central element into a living room! But it's important to remember that the objective of your living room is usually to be inviting to people, to have 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 space that visitors may not otherwise enjoy. Mirrors make rooms look larger (and lighter) and very usefully, they are able to reflect the door, so any seating that cannot face the entrance can still have the door visible through the use of mirrors. Once more, we need to adapt this principle to modern cities and homes, even though the best placement for a mirror is the place where it can reflect a gorgeous view.
