An interior design consultant advises clients on topics related to the design of interior space. They design plans personalized to their clients tastes that also serve a functional purpose. Interior design consultants often work for design consulting firms, but some are self-employed and work as independent consultants. People with an eye for color, lighting, texture, and space make excellent interior design consultants. They usually work full time during business hours but often accommodate their clients schedules, meeting with them during evenings and weekends.
