Symmetry is something that is everywhere we look and it created balance and harmony within a design. It is one of the fundamental principles of gestaltism, a behaviour theory in which our mind naturally creates order and completeness in the things we perceive.
Within cabinet design, the most common type of symmetry is called Bi-lateral symmetry which is where an object is reflected across a plan to create another instance of itself.
Where symmetry cannot be found or created, we must use asymmetry to emphasise strong points of interest, uniqueness and character. Because our mind notices that something isn’t symmetrical, it draws the eye towards the object that omits itself from the symmetry, making it the focal point.
