As a minimum there should be sufficient storage for all the following to be totally put away out of sight:
- dining tables and associated paraphernalia such as recycling trollies
- demountable stage and sound / AV system
- PE equipment
- Adult chairs for a full concert performance from parents
- Community store
There is NEVER enough space allowed in school design guidelines - in designing new hall spaces all schools should demand more than recommended guidelines and also demand that architects model how the storage will actually cope with the amount of 'stuff' that schools have to have to be able to function. Current practice is not good enough!
