Interior design is the art or process of designing the interior decoration of a room or building, it is often a very involved process that takes sometimes to fine tune and create a space with the vision of the client an a solid idea. I could undertake projects that include arranging the basic layout of spaces within a building as well as projects that require an understanding of technical issues such as acoustics, lighting, temperature, etc. Types of interior design include residential design, commercial design, hospitality design, healthcare design, universal design, exhibition design, spatial branding, etc. I think that this profession is consistently changing and evolving many fields, but the trick is to understand how people are influenced by their closer environments.
