There no longer being a stable classification of work activities, the spaces dedicated to them must be highly flexible and adaptable to changing needs. These should be determined by specific corporate needs - such as the need to represent the corporate image in elegant welcoming spaces, or give prestige to the executive offices - and, above all, by the advent of new functionality inherent to modern professional activities. Just think of the new concept of productivity, which evolved from a mere mechanical performance of tasks into a psychological condition to be improved: such as in the case of the Lufthansa Training Center, a fine example of how important it was, when constructing a new building, to turn to a producer such as company, whose collections offer a range of products so wide that it was able to meet the needs of the many different spaces inside the complex.
