Interior decoration is the art and science concerned with the improvement of the interior of a structure to make it aesthetically pleasant for the visitors using the room, as well as for the occupants of the room. An interior decorator is a person who plans, coordinates, oversees, and carries out these improvement projects. In general, there are two types of interior designers: the consultants and the planners. Although both have significant input in the process of improving the interior of the structure, yet the planner has more skill and authority, since he has made the decisions on how to go about the project.
There are many styles of interior decoration; however, the most common among them are the classical styles, the Colonial style, French style, English country style, Gothic style, and the Post-colonial style. A notable addition to the field of interior design is the concept of mixing and matching different styles to come up with a unique and stylish interior decoration. Some of the popular styles are American colonial style, art Deco style, Art Nouveau style, Classical style, Georgian style, German and Italian minimalist style, Hawaiian, Japanese, Moroccan, Post-modern, Renaissance, Romantic style, Victorian, furniture styles, and contemporary style.
Interior design styles have an influence on the way interiors are decorated. One of the main differences between a classical style and a contemporary style is the choice of materials to be used in the decoration. For classical style, the primary material to be used is wood. For the other styles, either real or synthetic materials are used. The choice of the materials used in interior decoration depends on the theme of the design, the general atmosphere desired, and the practicality of the choice.
