Interior design is the art of making the inside of any building (commercial or residential), giving it a cohesive look and feel. An interior designer is that person who practices the craft of interior design. He or she is often very creative and make old places new. Done well, interior decorating can give new life to a dull room by making what may appears to be a few simple changes.
An old room can be re-purposed for a new function and an interior decorator will be needed to help make this happen. Changes made can range from using new color palettes, to changing fixtures and or other decorative pieces like vases, throw cushions and even pieces of furniture. A designer will often work with clients to find out what their tastes are, and find ways to bring that to life in their design.
