Project design

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.
