When planning the location of spaces within the school buildings it is worth considering which spaces are most likely to change. Broadly speaking there are three types of space:
• Those that are unlikely to expand (e.g. the reception area and head's room);
• Those that are likely to grow to suit extra numbers (e.g. the hall or staff room) although this will depend on frequency of use;
• Those that will be replicated (e.g. classrooms).

The size and shape of individual spaces may also reduce the need for adaptations. Limiting the depth of spaces to one or two dimensions could make adaptation simpler, for example. Standard ceiling heights (as far as possible) makes changes in room size more straightforward.

The location of services and major structural elements will also have an effect on adaptability. This includes main service risers, staircases, any lifts and plant rooms. If drainage runs are kept to the perimeter of buildings, they can remain undisturbed if partitions are moved about. Heavily serviced spaces
should be positioned to allow future adaptations to rooms and functions. There are times when temporary accommodation is needed to cope with fluctuations in pupil numbers. Temporary buildings can be useful as a short-term measure, but they should not be seen as a cheap alternative to permanent buildings. Their construction tends to have inherent disadvantages such as poor environmental conditions, lack of insulation, poor acoustics and lack of security.
