The concept of balance as it refers to the interior means achieving visual equilibrium through the arrangement or proportion of parts of the whole. We can achieve balance in our spaces through reaching equilibrium among varying forces of weight, texture, color and size. Balance in design is can be achieved in a variety of ways; the easiest (in my opinion) being symmetrical balance. A nightstand on either side of a bed, two end tables flanking a sofa, a dining room table are several common examples of symmetrical design within our spaces.
Asymmetrical balance means balance without symmetry. Imagine a scale with one large object on one side and a cluster of small objects on the other side; balance is still achievable without symmetry.www.stephenschubel.com
As you can see in the living room design by Stephen Shubel, the objects within the space are not symmetrical; one side does not mirror the other. But you can see elements on one side that reflect the other; the basket in the lower right of the frame balancing the rope end table in the middle left of the frame. A smaller lamp is lifted by books to move the two lampshades onto the same plane.
Asymmetrical designs lend themselves to a more interesting and interior space; the difficulty arises in the lack of organization. To successfully achieve balance with asymmetry, you have to consider careful placement of objects and accessories while maintaining balance in color, texture, lines, and shapes within your space.
