Purpose – This paper presents the research findings of a Post-Occupancy Evaluation of new ways of working at the Faculty of Architecture of the Delft University of Technology and the lessons that can be learned from this particular case in connection to research findings from similar cases. Design/Methodology/Approach – The article is based on an internet survey among 266 daily users, additional interviews with decision makers and other participants involved in the implementation process, analyses of documents and personal observations. Findings – The new office plan scores high on possibilities to meet other people. Work spaces are considered to be functional, but employees also reported a lack of spaces suited for confidential (telephone) conversations and insufficient visual and auditory privacy. Employees can insufficiently control the climate of their direct work environment and the way the environment looks like. Security of the workplaces is rated below average. People want more rooms equipped with doors, and doors that can be locked. Another important complaint was lack of personal and collective filing and storage possibilities. Research limitations – The paper focuses on office space; because of limited time and budget restrictions educational space was not included in this building-in-use study. There was no opportunity to conduct a zero measurement ex ante. Long term effects on use and experience are not known yet, nor the effects of improvements that are being implemented this year. Practical implications – The results can be used to support decision makers in implementing new office concepts, in general and in particular in an academic setting, ex post or ex ante. Originality/value – Much has been written about new ways of working, but research on this topic in academic settings is scarce@en
