The space list is a compilation of all the spaces mentioned in the brief. The list is usually set up as a decomposition that starts with the buildings main functions, which are then decomposedbroken downinto smaller sub-functions and individual rooms until subdivision is no longer possible or desirable. For example, if a client needs a conference centre, this general demand can be broken down into specific subparts, specifying different types of meeting facilities (e.g. various kinds of large, small, formal and informal meeting rooms) and ancillary functions (e.g. cloakrooms, break areas, furniture storage). The objective of such a breakdown is to create a comprehensive overview of the clients spatial needs and to ensure that no essential rooms are forgotten. It is important to note, however, that the room list does not necessarily have to specify every single room that needs to be created in the building. Toilets, for example, usually do not need to be defined in detail because the design team can be expected to know the relevant standards for such spaces. Capacities and sizesThe space list gives concrete figures for the requested quantities and sizes of spaces. This can be done in different ways. For a meeting room, for example, size can be expressed in functional terms by referring to the number of meeting seats (e.g. the room should be large enough to accommodate 10 seats), but it is also possible to define size in terms of concrete square metres (e.g. the room should be at least25 sq.m.). The latter is strictly speaking unnecessarythe design team can makethat translationbut most clients do both because the use of square metre requirements allows them to keep track of the overall size of the project. 38
