Principles of interior design are the ways different design elements are arranged.
It is the proper distribution of objects so that it creates a visual balance. Lack of balance alters a composition’s harmony. There are three styles of balance: asymmetrical, symmetrical and radical. Traditional interior designs have symmetrical balance. This means there will be repetition of same color throughout the space. Asymmetrical balance is having different objects that have the same visual weight. This is more casual but is hard to achieve. Radical symmetry is when the elements are arranged around a center point. A spiral staircase is a good example of radical balance.
Space refers to the area in and around an object. The designer’s challenge is to arrange design elements in space. Three dimensional designs consist of form, length,width, height and space.We need both small and large areas to satisfy our mind. There should be a balance between filled and unfilled area. Both positive and negative spaces are important in a room as well.
Focus means the attention placed on a piece of work. It can be made by contrasting elements so that it grabs attention. Every room and space must have a focal point. For example, a fireplace is a common focal point. A large piece of furniture can also be a focal point. Painting one area of your room differently can also act as a focal point. A focal point must provide a lasting impression.
When designing a house, you should think of the house as a total entity. All the rooms and spaces must be linked; that is, there must be a common style all the way through. So, plan well before you start designing a house or space.
