The training and function of interior designers should not be confused with that of interior decorators. Whereas the decorator’s function usually begins once planning and building are completed, an interior designers' function should ideally begin with the concept and continue through the planning and technical details to completion of the project.
Interior designers plan attractive and functional domestic and commercial human environments in buildings, taking into account the function, space available and space required by their clients.
Interior designers’ work is influenced by many factors, such as:
Thus, designers need to have a thorough knowledge of architectural design, technical service, technical drawing and construction methods, as well as building materials, to assist in the planning and execution of the project.
Once the interior space has been planned to suit the client’s needs, the coordination of colour schemes, finishes for walls, floors and ceilings, as well as the choice of furniture and accessories, must be completed in order to create a satisfactory and functional total environment. Each room is planned separately, bearing in mind the purpose and intended function of the room, who the occupants will be, which colours are suitable, and whether the atmosphere is to be formal or informal.
Ideally, interior designers should consult with their clients personally, to obtain enough information concerning the people who will occupy the building to satisfy their requirements. A central theme is usually chosen and furniture and colour schemes are planned accordingly.
To achieve harmony, colours need to be chosen carefully. Although interior designers follow modern trends and fashions, they also need some knowledge of earlier styles in order to satisfy clients who prefer retrospective classical periods, for example, Victorian or Regency.
Practical considerations, such as the prevailing climate, location of the building, and the available budget are some of the factors that have to be borne in mind. It is, therefore, advisable that the designer, the owner and the architect all become acquainted with the building site.
Before work begins, the interior designer must produce detailed drawings and sketches of the design, specifications for the work to be done, the material and finishes needed, together with an analysis of the costs, for acceptance and approval by the owner and architect. The interior designer must also attend to any problems that may arise once the work has begun, and do a final check to ensure that all the requirements and specifications have been adhered to and completed.
The nature of the work also necessitates visits to shops and factories, as the designer needs to be well informed about new developments and products on the market. Business can be transacted in offices, at sites during construction or in clients’ homes.
