Interior designers work to create many kinds of indoor environments, including residential, medical, educational, cultural, civic, and commercial. Commercial interior design includes a broad spectrum of interior commercial spaces and environments, including offices, retail stores, restaurants, and other spaces where business is conducted.

At a minimum, these commercial interior spaces must be designed to be functional to conduct business efficiently for the company occupying the building. Well-designed interior spaces are essential for business. The layout and flow of an office or retail space is critical to the experience of both clients and employees, which directly impacts the long-term success of the business.
