Building depth, room depth, window axis dimension and the layout of a building tell us nothing about how suitable it may be for the user or about general area efficiency. Instead, different industries have different spatial and workplace concepts – depending on workflow or style of internal communication and corporate culture.

Creative users, IT companies and call centers often work with more open layout and prefer greater building depths; consulting firms and law offices tend to choose the classic cubicle set-up and usually find that the most effective space layout is in a building depth of around 13 meters.
