Interior Design Vs Interior decorating Vs Home Staging Vs Interior Redesign - What's the Difference?

The other day a real estate agent whose listings I stage for sale introduced me to someone as a "designer". I didn't want to take the time to correct him, but I thought to myself, "This isn't the first time I've heard people use 'designer' erroneously. It's often used to label someone who's an interior decorator. So, why does everyone lump us all in one category, when we all clearly do something different? "thiết kế nội thất nhà phố 

To put the differences succinctly:

Interior design involves, among many other things, the preparation of documents often by a licensed professional for the construction of an interior space such as plans and elevations, and details and specifications, including lighting, power and communication locations, materials and finishes, and furniture layouts.

Interior decorating involves the adornment of surfaces in the interior space, such as fabrics, wall coverings, furniture, decorative accessories, flooring, light fixtures etc., and takes into account the lifestyle, taste, needs and preferences of the user of the space. While interior designers may decorate, interior decorators don't design.

Home Staging is preparing the home for sale through updates and "decorating" so that it appeals to the broadest range of buyers for the market that the home is in.

Interior Redesign is often done by home stagers for homeowners not currently selling because it employs many of the same principles that home stagers use, such as primarily using what furniture and decorative accessories the homeowner already has, with an eye towards the future sale of the home.
