ABSTRACT
A building consists of an assembly of materials and components, joined together in such a way as to allow the building to fulfil its primary purpose, that of providing shelter to its occupants. This primary function may be augmented by other supplementary functions; for instance, the building may be used for certain activities, a factory will be used for the manufacture of products, a warehouse will be used for the storage of goods, a leisure centre will be used for the pursuit of leisure activities, whilst a concert hall will be used to house entertainment activities. Nevertheless, they will all need to satisfy the primary objective of providing shelter to the occupants.
