An Interior Designer implies that there is more of an emphasis on Planning, functional design and effective use of space involved in this profession, as compared to interior decorating. An interior designer can 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. Although an interior designer may create the layout of a space, they may not build the space without having their designs stamped for approval by an architect, which is why many interior designers also complete school to become architects as well. An interior designer may wish to specialize in a particular type of interior design in order to develop technical knowledge specific to that area. Types of interior design include residential design, commercial design, hospitality design, healthcare design, universal design, exhibition design, spatial branding, etc.
Other areas of specialisation include museum and exhibition design, event design (including ceremonies, parties, conventions and concerts), theatre and performance design, production design for film and television.
