Interior design is an art and science of improving the interior of a space to create a more aesthetically pleasing and healthy environment for those using the room. An interior designer is usually someone who designs, plans, researches, and coordinates these improvement projects. He or she will usually work with architects, plumbers, builders, and interior furnishings buyers. Designers will often work on projects independently but will collaborate and work with other professionals when the design process is complete. An interior designer will often work as a team to get multiple projects accomplished.
Interior design is usually separated into two categories; commercial interior design and residential interior design, depending on whether the project is a company office or retail space, or a private house or property.
Interior design encompasses a wide variety of styles. They include classical, classic, modern, Georgian, French, country, and even contemporary. These styles can be distinguished by the types of materials used and the color schemes used. Materials used can be wood, stone, glass, steel, mirrors, textiles, and concrete.

Contemporary interior design is characterized by a focus on practicality, as well as a recognition of natural light and a willingness to use textures and color to enhance functionality. This style is not overly concerned with traditional design styles and looks very modern. A typical contemporary designer will use various textiles, fabrics, furniture, textures, lighting, and paint to create spaces that are practical, useful, and beautiful. This style can include both traditional and non-traditional elements.
Georgian interior design styles are characterized by intricate detail, heavy furniture, and a lack of ornamentation. This style can be considered very timeless and has a history that goes all the way back to the sixteenth century. In Victorian times, there was a real emphasis on the flowing lines of the Victorian age. Designs often included curved doorways, brackets, open kitchens, and large, column-style windows.
In terms of building permits, this style of interior design requires a permit if you are going to use many modern elements, such as glass panels. If your building will have more elaborate features, such as marble floors or granite countertops, then you may need an additional permit. The permit you get will depend on the style you intend to use for your building. The building permit is the key to being able to build the interior environments you want. You will need to visit your city government offices to find out what the requirements are for your particular area.
Horizontal lines are a critical part of modern or contemporary interiors. In a horizontal space, walls are spaced closely together and floors are parallel to the walls. Although this is a basic configuration, it is easily adapted to many different styles. A vertical line is used in horizontal spaces, but in a horizontal room, you must use vertical lines.
When you are planning your interior design, make sure to keep the above details in mind, and perhaps enlist the help of a reputable creative design agency to assist with expert guidance and consultation.
