This chapter presents a series of short summaries of design briefs for real-life projects covering a diversity of building types: -Office: Entra head office Oslo (NO)-Detention facility: (anonymized)-Library: Library of Birmingham (UK)-School: IKC Zeeburgereiland (NL)-Hospital:Aalborg university hospital (DK)-Sport facility: Swimming pool/sports hall Papendrecht (NL)-Laboratory: Panum Institute Copenhagen (DK)-Train station:Alkmaar station (NL)At first sight, the briefs for these projects seem to have a lot in common with one other as they all make use of the same kind of wording, stating that the new accommodation solution should be efficient, flexible, functional, sustainable and so on. This suggests that all the clients involved have similar ambitions, but although this is true to a certain extent, a closer look reveals numerous differences.The most obvious differences can be seen in the room lists and functional briefs. For example, the brief for the school asks for classrooms and playgrounds, whereas the brief for the hospital project asks for patient rooms and surgery rooms. The names of these rooms alone tell us a lot about the different types of activity they are expected to accommodate. More detailed differences emerge in the technical requirements, which tend to focus on those building components that are critical for the buildings operation. For example, the brief for the prison facility is very specific about the locks on the cell doorsa detail of strategic importance for this type of building. The brief for the train station pays a lot of attention to requirements for elevators, escalators and stairselements that are essential for the facilitation of passenger flows, and thereby the stations functioning.The topic of flexibility is addressed in a very similar way in all projects, but here, too, there are differences. The brief for the laboratory building asks for dance floors that allow lab equipment to be easily moved around. The brief for the school project asks for the capability to expand the number of classrooms from 10 to 16 during the summer vacation. As these small but critical differences demonstrate, different types of buildings entail different requirements, which is what makes briefing relevant in the first place.
