As successive BCO Specification Guides and the research of organisations like CoreNet Global have proved, the spatial dynamics of offices have changed dramatically in recent years. Put simply, the modern office serves significantly more people per square foot than ever before. Originally this tightening was largely down to the growing ubiquity of flat screen and the mobile devices, but more recently the major driver of change appears to be the gradual disappearance of personal workstations in favour of more shared space.The typical space allocated to an individual in a building has shrunk dramatically in the last few years, while the provision of public and meeting space has increased. The upshot is that the amount of personal space allocated to each individual in a building has fallen by over a fifth in just a few years and the very idea of using the number of employees to determine their individual space requirements without other considerations seems less relevant.
