An office is generally a room or other area in which people work, but may also denote a position within an organization with specific duties attached to it (see officer, office-holder, official); the latter is in fact an earlier usage, office as place originally referring to the location of one's duty. When used as an adjective, the term "office" may refer to business-related tasks. In legal writing, a company or organization has offices in any place that it has an official presence, even if that presence consists of, for example, a storage silo rather than an office.
An office is an architectural and design phenomenon and a social phenomenon, whether it is a small office such as a bench in the corner of a small business of extremely small size (see small office/home office) through entire floors of buildings up to and including massive buildings dedicated entirely to one company. In modern terms an office usually refers to the location where white-collar workers are employed.
The structure and shape of the office is impacted by both management thought as well as construction materials and may or may not have walls or barriers . The word stems from the Latin officium, and its equivalents in various, mainly romance, languages. Interestingly, this was not necessarily a place, but rather an often mobile 'bureau' in the sense of a human staff or even the abstract notion of a formal position, such as a magistrature. The relatively elaborate Roman bureaucracy would not be equaled for centuries in the West after the fall of Rome, even partially reverting to illiteracy, while the East preserved a more sophisticated administrative culture, both under Byzantium and under Islam.
