Office interior design: Interior spaces may be recycled and redesigned many times. Simply to accommodate is the changing needs of new corporate users. In many instances redesign may be necessitated solely by business. Moreover, the escalating costs of land acquisition and construction and the increasing scarcity of urban building sites make it essential that the redesign reflects an efficient, cost-effective utilization of space, as well as one that is responsive to the human factors involved. It is necessary, therefore, for the designer to be familiar not only with the general planning criteria associated with office design, but with the architectural detailing of some of the typical interior elements contained within these spaces.
