The six fundamental principles include axis, symmetry, hierarchy, rhythm, datum, and transformation. Axis is a line established by two points in space about which forms and spaces can be laid out symmetrical or balanced. Axis is a central line that supports to organization of a design.
Symmetry is simply one shape flipped precisely like another. The hierarchy is most often formed using a unique shape, size, color, or deliberate location or placement in architecture. Rhythm is created by merely using repeated forms. In architecture, repetition refers to a pattern with the same size, shape, or color used again throughout the design.
Datum is a method that ties together or secures all other elements of the design. It must have adequate size, closure, and consistency organized jointly within the given field. Transformation focuses on keeping a design but also strengthening the building through transformation.
