The living room image is very well balanced with many symmetrical elements.
Symmetry is one way to create a balanced design. There are many examples of symmetry in the living room image. There is a sconce on either side of the fireplace. The sconces enclose two identical pieces of art. Each side of the sofa is complimented by a light fixture. Even though the fixtures on the side of the sofa are not exactly the same, it is still a loose form of symmetry. The lounge chair has a basket to its right, which is similar to the fixture placements on either side of the sofa.
