Unity is the important first principle of Interior Designing. All the elements used should complement one another and a smooth transition should exist from one to another. A good understanding of Alignment of objects, Similarity of color/texture, Proximity (spacing) of objects, Repetition (grouping) of elements based on similarity, Continuation and Overlapping of interior design elements are a few ways to achieve ‘Unity’ in an interior design arrangement.
Balance is the important second principle of Interior Designing. Balance can be divided by three popular ways namely Symmetrical, Asymmetrical and Radial. In Symmetrical, a space is divided into two equal parts centered on a central axis and both the parts are equally compensated to give out a calm feel to the living space. In Asymmetrical, any odd number of elements can be used by keeping an imaginary central axis as the focal point. Though asymmetrical balance is a little hard to achieve when compared to symmetrical, the output is more natural and energetic when compared to the former. Radial balance involves a central piece (like a round dining table) from which all other elements seem to radiate to arrange themselves in circular symmetry.
Rhythm in design is all about creating patterns of repetition and contrast to create visual interest. You can achieve this by using the same color or shape at different intervals. you can establish a rhythm by using a color in the pillows, picking it up in a painting, and echoing it again in a rug. These repetitions will help carry your eye around the room. Rhythm can be achieved in any living space by following these two methods – Repetition, and Progression. Repetition refers to the repeated use of the design elements like color, texture and pattern or any other physical attributes like home décor items in an orderly way. In Progression, elements are arranged ascending or descending based or their size, color gradient or any other distinctive characteristic.
contrast can be achieved by three elements namely color, form and space. Contrast can also be achieved by combining two or more forms; for example one can combine a circular mirror and a rectangular sofa to balance and distribute the attention between both the items. One can also achieve contrast in a living space by dividing the available space efficiently into usable positive and negative spaces.
Harmony is created when all the elements act together to create a unified message. Just as rhythm can create excitement, harmony creates a sense of restfulness. you can create harmony by using just one color, even though your forms vary greatly in shape,, size, and texture.
F) Scale and Proportion
Be it the size, dimension, shape or color of the objects, a harmony should be established between them and a proportion has to be maintained. Proportion is the ratio between the size of one part to another, and scale is how the size of one object relates to another or to the space in which it is placed. For instance, a large overstuffed sectional in a small room will be out of scale. Some proportional relationships are more pleasing than others
