This investigation considered what physical environment would suit for workplace in public space. This research clarified that evaluations of users are good, when corner type arrangement is selected as workplace in outside investigation. However, we could not find the type of arrangement which users prefer in case of internal environment. Although variation of evaluation was found with the type of arrangement in case of internal environment, it also became clear that specific arrangement does not necessarily obtain synthetically high evaluation. Consequently, it is important to take in and to control variation of physical environment in case of outer environment in public space as workplace. On the other hand, it is necessarily to respond to demands of facilities in case of internal environment. By fulfilling these conditions, the possibility of the public space as workplace would spread.
