Few words about the interior design

The interior design ,the art to create beautiful and useful interiors, exist since the people have homes.
Althought people use the termins "interior design" and "interior decoration" alike, they have different meanings.

 The interior decorators focus on realising the area in an existing space,including the painting and the furniture.

But the interior designers look at the area as a whole ,from its function to the acoustic, including the decorations of the place.
