An interior designer works closely with architects to design the interior space . Decoration or decorating, is the furnishing of a space with beautiful or fashionable things while working within its functionality.
An interior decorator may recommend changing the layout of the furniture. In other words, decorators do not tend to design, whereas interior designers may design and decorate.
