Commercial interior decorating can create visually interesting spaces that follow a specific theme or bring a new level of interest to an otherwise unremarkable space. Good commercial decorating may go largely unnoticed, but can have a significant impact. It can add value to a business or building, or simply improve the space for those who spend time in it. Many reasons exist for a business or public agency to pay for commercial interior design. In the case of retail shops, a well-designed space may be more attractive to customers, getting more people to enter the store and persuading them to spend more time there. In other cases, a commercial interior design project may have goals such as establishing a theme that projects a particular corporate image.
