Interior design is the art and science of creating physically comfortable and aesthetically pleasing interior environments. It combines practical knowledge with artistic sensibility. Interior designers are professionally trained in planning spaces that enhance the function, safety and aesthetic quality of working and living environments.

In addition to making space aesthetically appealing, interior designers must design space to conform to federal, state, and local laws, including building codes. Designs for public areas also must meet accessibility standards for the disabled and the elderly.

Interior design is a service profession. Interior designers work with many different people on a variety of projects. Good communication skills, both visual and verbal, are necessary when working with clients, contractors, architects and others involved in design projects. 

Visual communication is a key component of interior design.  After consulting with the client, designers create detailed designs, using drawings, a structural model, computer simulations, or a full-scale prototype. Many designers use computer-aided design (CAD) tools to create and better visualize the final product.

Completing a degree in interior design is increasingly important for those wishing to enter this dynamic and evolving profession. Interior design is the only design field subject to government regulation. The American Society of Interior Designers lists the  licensing requirements in those states requiring licensure.
