At the end of this article you’ll be able to recognize and use the basic interior design principles used by every interior designer to create a great design, and who knows maybe you’ll also save some money, or start a new career ! Now let’s begin with the beginning, and undestand what interior design is …
“Interior design is the process of shaping the experience of interior space, through the manipulation of spatial volume as well as surface treatment. Not to be confused with interior decoration, interior design draws on aspects of environmental psychology, architecture, and product design in addition to traditional decoration.
An interior designer is a person who is considered a professional in the field of interior design or one who designs interiors as part of their job. Interior design is a creative practice that analyzes programmatic information, establishes a conceptual direction, refines the design direction, and produces graphic communication and construction documents. In some jurisdictions, interior designers must be licensed to practice.” - Source :Wikipedia
Now that you have an idea about interior design, we can move forward and learn something really useful, the principles of interior design. Let’s begin !

When doing interior design it is necessary to think of the house as a totality; a series of spaces linked together by halls and stairways. It is therefore appropriate that a common style and theme runs throughout. This is not to say that all interior design elements should be the same but they should work together and complement each other to strengthen the whole composition. A way to create this theme or storyline is with the well considered use of color. Color schemes in general are a great way to unify a collection of spaces. For example, you might pick three or four colors and use them in varying shades thoughout the house.

In a short sentence for those who just scan this article balance can be described as the equal distribution of visual weight in a room. There are three styles of balance: symmetrical, asymmetrical, and radial.
Symmetrical balance is usually found in traditional interiors. Symmetrical balance is characterized by the same objects repeated in the same positions on either side of a vertical axis, for example you might remember old rooms where on each side of a room is an exact mirror of the other. This symmetry also reflects the human form, so we are inately comfortable in a balanced setting.
Asymmetrical balance is more appropriate in design in these days. Balance is achieved with some dissimilar objects that have equal visual weight or eye attraction. Assymetrical balance is more casual and less contrived in feeling, but more difficult to achieve. Asymmetry suggests movement, and leads to more lively interiors.
Radial symmetry is when all the elements of a design are arrayed around a center point. A spiral staircase is also an excellent example of radial balance. Though not often employed in interiors, it can provide an interesting counterpoint if used appropriately.

Interior design’s biggest enemy is boredom. A well-designed room always has, depending on the size of it, one or more focal points. A focal point must be dominant to draw attention and interesting enough to encourage the viewer to look further. A focal point thus must have a lasting impression but must also be an integral part of the decoration linked through scale, style, color or theme. A fireplace or a flat tv is the first example that most people think of when we talk about a room focal point.
If you don’t have a natural focal point in your space, such as a fireplace for example, you can create one by highlighting a particular piece of furniture, artwork, or by simply painting a contrasting color in one area. Try to maintain balance, though, so that the focal point doesn’t hog all of the attention.

If we would speak about music we would describe rhytmas the beat of pulse of the music. In interior design, rhythm is all about visual pattern repetition. Rhythm is defined as continuity, recurrence or organized movement. To achieve these themes in a design, you need to think about repetition, progression, transition and contrast. Using these mechanisms will impart a sense of movement to your space, leading the eye from one design element to another.
Repetition is the use of the same element more than once throughout a space. You can repeat a pattern, color, texture, line, or any other element, or even more than one element.
Progression is taking an element and increasing or decreasing one or more of its qualities. The most obvious implementation of this would be a gradation by size. A cluster of candles of varying sizes on a simple tray creates interest because of the natural progression shown. You can also achieve progression via color, such as in a monochromatic color scheme where each element is a slightly different shade of the same hue.
Transition is a little harder to define. Unlike repetition or progression, transition tends to be a smoother flow, where the eye naturally glides from one area to another. The most common transition is the use of a curved line to gently lead the eye, such as an arched doorway or winding path.
Finally, contrast is fairly straightforward. Putting two elements in opposition to one another, such as black and white pillows on a sofa, is the hallmark of this design principle. Opposition can also be implied by contrasts in form, such as circles and squares used together. Contrast can be quite jarring, and is generally used to enliven a space. Be careful not to undo any hard work you’ve done using the other mechanisms by introducing too much contrast!

Another important element of interior design where it is necessary to take infinite pains is details. Everything from the trimming on the lamp shade, the color of the piping on the scatter cushion, to the light switches and cupboard handles need attention. Unlike color people find details boring. As a result it gets neglected and skimmed over or generally left out. As color expresses the whole spirit and life of a scheme; details are just as an important underpinning of interior design. Details should not be obvious but they should be right, enhancing the overall feel of a room.
Scale and Proportion - These two design principles go hand in hand, since both relate to size and shape. Proportion has to do with the ratio of one design element to another, or one element to the whole. Scale concerns itself with the size of one object compared to another.
Color - Colors have a definite impact on the atmosphere that you want to create when doing interior design. A more detalied post about how colors affect our moods you can find here.

I do agree that those are the most important design principles. Unity and harmony was probably the most important of the two because you have to have great unity and they need to go with each other to make sure the blends and mixture of colors and materials works to make it look great. To check out some creative interior designs, check out HGTV’s 2nd season of Design Star. It’s a show about 11 aspiring designers competing to win their very own show.Check out the site http://www.hgtv.com/designstar for all info and details.

Fantastic article.
>it is necessary to think of the house as a totality
I think you should put this in bold because it’s probably where most people go wrong (right of the start).
Great explanation of the different design elements/considerations also.

I’m glad you like it.
That was very interesting. That gives me a good idea of the role of an interior designer. It gave me fresh ideas and a nice beginner’s lesson.
Thank you
Thanks for the post!
In my opinion the report is FANTABULOUS and makes someone like me who is a novice to perceive the basic fundamentals of POD thoroughly.
Wishing you best of luck for future!
Do you have any info on LINES of Interior Designing???? and how to spot the LINES in a picture???
Thank You
well: it’s really an iconic article about the interior design.I, m damn sure that i’ll save my money if do the continous visit to your website; instead of doing a part time course.
It would be a better plat form for the freshers, if some more information like; basics in size and scale measurement are added to the article.
THANKS and Awaiting for favourable artcles.
