As an Interior Designer I thoroughly consider that to make a project successful an Interior Designer should encompass and understand the following qualities and principles:
Good communication skills: Interior designers often work one on one with clients, service providers, and contractors or as part of a team. Therefore, a designer must have the ability to work with different personality types, be good listeners and communicate clearly.
Management skills: Deadlines are a natural part of the professional interior design world. Clients may have specific deadlines for a designer to meet so project management skills are essential to maintaining order and meeting deadlines.
Planning Skills and Design Know-How: most essential qualities of a designer is the ability to plan a space according to a client's needs. In addition, an interior designer must know how to visually render his plan with drawings, computer-aided design software or scaled models so a client can see the designer's ideas. Interior designers must know how to create a desired look and feel through the use of colors, lights, furniture, flooring and fabrics, as well as how to artfully arrange these elements. They must also read blueprints and know city building codes to maximize the safety of their designs
Design Principles an Interior designer must apply:
